Donie's Ireland daily news BLOG update

A spring statement showing five ways it will affect your pocket

  • After Irish Water debacle Government is planning absolutely no nasty surprises.
  
Minister for Finance Michael Noonan speaks delivered the Government’s spring economic statement. He predicts tax reductions and extra Government spending in the Budget.
The spring statement set the goalpost for the budget, but did not give us the detail. We don’t have the budgetary tables of who wins and who loses and by how much and the typical budget day examples such as “Mary”, the single public servant earning €40,000, or “Michael and Siobhán”, the couple earning €85,000. But clear hints have been dropped by Minister for Finance Michael Noonan and Minister for Public Expenditure Brendan Howlin about how the spoils of economic growth will be divided.
Some €1 billion was distributed in tax cuts and spending hikes in the 2015 package presented last October. For next October the indications are that there will be at least €1.5 billion to spare.
Here are five things that this all means for your pocket:
1 Lower tax and charges on pay packets: The Government cut the USC and income tax modestly in the last budget, with tweaks made to claw back some of the gains from those earning more than €70,000 a year. We can expect more of the same in the next budget, as Noonan confirmed when he launched a strong defence of the Government’s tax strategy. Tax cuts of over €600 million are expected next October, compared to €400 million last October.
If the Government is re-elected, Noonan made clear that we can expect more of the same in the years ahead.
Next October we can expect a further increase in the standard rate tax band – single earners now enter the higher 40% income tax rate at €33,800 and this income limit will likely rise, benefiting anyone earning over that level. As happened last year, USC changes are likely to benefit lower and middle income earners in particular.
Last year’s budget boosted after-tax income by 1 -1.5% for most earners with the biggest gains going to a group of lowest earners excluded from USC and to those on incomes of €35,000 to €75,000 for a single earner.
So if, as expected, the Government goes for a “same but a bit more” approach next October, the gains for many will be about 1.5 – 2.5% in terms of a boost to take home pay.
Tax cuts will benefit people’s pockets, but the return of cash is gradual. Tax hikes during the crisis totaled about €10 billion. There were tax cuts of about €400 million last October and a further €2 billion might be affordable over the next three years. So in rough terms taxpayers might get a quarter of the emergency hikes back by 2018.
2 Rising public sector pay: There is no doubt that rising public sector pay in some form is now on the agenda, with Howlin getting Cabinet clearance to commence talks with the unions. How much this will take of the €600 million – €750 million available for day-to-day spending increases next year is not clear. The public pay bill is about €14 billion so the gross cost of each 1% rise is €140 million, though the net cost is lower as the exchequer gets about 30% of any rise back in higher income tax. Howlin was cautious, but he did say in relation to public pay that “the unwinding of the measures will take time”.
The Government will consider increases – the issue is how quickly and on what basis. One option would be to focus initially on the pension levy, which was introduced in 2009 and takes about 7.5% from an average public sector salary. Overall, however, like tax cuts, it is a long way back after pay cuts of 14-15% for most public servants.
3 Increases in Government payments and subsidies: Howlin mentioned the social protection budget as one area set to get more cash. This means more in payments in some areas. In the last budget, the monthly child benefit payment was increased by €5 and another rise can be expected in October. Last year the living-alone allowance paid to 180,000 older people was also increased and more of this kind of targeted payment rises can be anticipated too.
Howlin also referenced a special group examining childcare issues and more help for younger families looks likely. This could involve either subsidies for childcare costs or some kind of tax relief. A second free preschool year is also being examined, as is subsidised after-school activities.
4 No nasty surprises on the way: After the water charges row, the Government is going to do absolutely nothing to raise any additional taxes or charges, no matter how small. There was nothing in the statement that might cause even a hint of controversy. Noonan did say, however, that the property tax and water charges must remain in place.
5 Banking bonus: It is clear that the main banks are gearing up to cut their standard variable mortgage rates and that the Government will take whatever credit it can. Noonan said he will call in the main lenders and would not be likely to do so unless he felt that reductions were imminent.
Those in mortgage arrears are also promised more options in a new package to be unveiled over the next few weeks.

Men from the construction industry ‘account for half of male suicides in Ireland’

  • Report for CIF and Pieta House suggests a high number of deaths among those in production-type jobs
  
Mind our Workers: a new campaign by the Construction Industry Federation and Pieta House aims to raise awareness of suicide and mental health issues in the sector.
Men working in construction and production jobs accounted for nearly half of all male deaths by suicide in the period 2008 to 2012, a new report suggests.
An estimated 1,039 men from a construction or production background died by suicide during that period out of a total of 2,137 male suicides, according to figures published by the Construction Industry Federation (CIF).
Mind our Workers, a campaign to raise awareness of suicide and mental health in the sector, was launched on Tuesday by the CIF and suicide prevention charity Pieta House.
A report commissioned by the organisations notes there has generally been little data available on the professional background of people who have died by suicide in Ireland.
But in recent years, the National Office for Suicide Prevention commissioned the National Suicide Research Foundation to undertake a study and to establish a suicide support and information system (SSIS).
In the second phase of that study, some 307 cases of suicide in Cork between September 2008 and June 2012 were examined (275 suicides and 32 open verdicts at inquest).
Of the 307 deaths, 246 (80%) were males. Some 120 of those had been working in the construction/production sector, a total of 49%.
This was more than triple the number of deaths accounted for by next highest sector, which was agriculture.
By extrapolating from the trends identified in the research and applying them to the national data, the researchers said “it could be soundly estimated” that at least 1,000 suicides came from a construction/production professional background between 2008 and 2012.” This rose to 1,039 when directly extrapolated from the second phase of the study.
Men account for 108,300 or 93% of the total 116,700 working in the construction sector, the Mind Our Workers report notes.
Ten people a week in Ireland die by suicide and eight of those are men.
Some 6,520 suicides took place between 2000 and 2012 – 81% or 5,263 were male.
Between 2008 and 2012, there were 2,137 male suicides.
Pieta House chief executive Brian Higgins said the organisation was delighted to initiate the campaign in partnership with the CIF.
“It is extremely encouraging that a national body as influential as the CIF sees the impact of suicide on the construction industry and its employees and is partnering with an organisation such as ourselves to help tackle the issue. Partnerships such as this are a way of building resilience within our society.”
CIF director general Tom Parlon said the suicide figures for the sector were “shocking”.
“The industry can’t ignore this problem – there is a necessity to take steps to try to help those in need. Given the amount of time people spend in the workplace, that is where the Mind Our Workers campaign will focus. By promoting a more open approach amongst construction workers and their colleagues we hope it might reduce the number of people who feel they have no way out.”
CIF president Michael Stone said the organisation wanted to see a working environment where it was acceptable for men to ask their friends and colleagues, “Are you ok?”
The ‘Mind Our Workers’ campaign will run throughout the year. Campaign leaflets will be distributed throughout the industry and briefings and workshops will also be organised for CIF members.
Pieta House representatives will also attend regional branch meetings to discuss suicide and mental health.
A series of ‘toolbox talks’ about mental health and suicide will also be organised at workplaces and construction sites.
Separately, more than 100,000 people are expected to participate in the seventh annual Darkness into Light event for Pieta House in the early hours of Saturday May 9th.

No extension to insurance loading date from Leo Varadkar

  • Lifetime Community Rating will begin on May 1
    
The Minister for Health, Leo Varadkar, has confirmed that there will be no extension to the starting date of Lifetime Community Rating, which is due to come into effect at the end of this week.
From May 1, members of the public aged 35 and older who do not have private health insurance, but then choose to take it out, will be charged extra.
Known as Lifetime Community Rating, these consumers will see their premiums permanently loaded by 2% per year from the age of 35. For example, if a 54-year-old decides to take out private health insurance for the first time after April 30, they will have a loading of 40% added to their premium every single year that they remain insured.
The maximum loading is 70% and this will apply to people aged 69 and older who take out insurance for the first time after April 30.
According to Minister Varadkar, this system ‘will help to ensure that older and sicker citizens can still afford health insurance because the healthy and young who do not make as many claims still pay into the system’.
“It will also help to stabilise the market by encouraging people to retain health insurance once they have it. This is an essential measure to protect our system of community rating whereby everyone pays the same premium for the same policy regardless of their age or their health status,” he said.
He added that private health insurers are recording a higher volume of calls and internet enquiries this week and phone lines are remaining open late each night to deal with this.

Women who breastfeed ‘can lower the risk of dying from breast cancer’?

   
Women breastfeed their children during a pro-breastfeeding protest in central London in December
Breastfeeding significantly reduces the risk of being killed by breast cancer, a new study has suggested.
Women with the disease who breastfed their babies have a significantly lower risk of the cancer killing them or recurring, according to the paper.
Scientists found a history of breastfeeding lowered the risk of dying by 28 per cent and reduced the chance of the cancer coming back by 30 per cent.
The study, by US health care provider Kaiser Permanente, used data from 1,636 women with breast cancer who completed a questionnaire about breastfeeding.
Breastfeeding had a clear protective effect, especially in relation to particular types of tumour including the most common hormone-sensitive strain.
The protection was strongest for women who had a history of breastfeeding for six months or longer.
Lead researcher Dr Marilyn Kwan said: “This is the first study we’re aware of that examined the role of breastfeeding history in cancer recurrence, and by tumour subtype.
“Women who breastfeed are more likely to get the luminal A subtype of breast cancer, which is less aggressive, and breastfeeding may set up a molecular environment that makes the tumour more responsive to anti-oestrogen therapy.”
Luminal A breast cancer includes oestrogen-positive tumours which are driven by the female hormone and are the most commonly diagnosed form of the disease.
These tumours are less likely to spread to other parts of the body than other types and are treatable with hormonal drugs such as tamoxifen and aromatase inhibitors.
Why women who breastfeed their babies develop less aggressive tumours is not entirely clear.
Co-author Dr Bette Caan, also from Kaiser Permanente, said: “Breastfeeding may increase the maturation of ductal cells in the breast, making them less susceptible to carcinogens or facilitate the excretion of carcinogens, and lead to slower growing tumours.”
The research appears in the Journal of the National Cancer Institute.

Irish meteor hunters some tips to find one,

  • Here are 5 steps to finding a recent meteorite
   

Irish meteor hunters pay attention, here are 5 steps to finding the recent meteorite

Those on the island of Ireland who may have spotted a giant flare-like streak in the sky were intrigued to discover that it was in fact a rare meteorite, pieces of which could be worth thousands of euro to its finders.
Perhaps even more eyebrow-raising for meteorite hunters is that the very rare event – approximately twice a year – is so unusual that each piece of the meteorite could be worth 10 times the price of gold at its current rate, which could put it as high as €10,000 per piece.
According to David Moore of Astronomy Ireland, the best guessas to where it landed is most likely in the north of the island and he is now calling on every camera that may have recorded the incident sometime around 10.10pm on Sunday, 26 April to bring forth their footage to better locate the smoking piece of space debris.
Despite Ireland’s small size compared with the rest of the planet, it’s understandably difficult to find a small piece of rock, with the last recorded finding not even occurring this millennium, having been discovered in Leighlinbridge, Co Carlow back in 1999.
Given its rarity, it might be a little daunting to meteorite hunters as to how to actually find the smoking gun/rock, which is why, in their infinite space wisdom, Space.com has previously detailed the essential five steps to making a big find.
  1. Finding a potential spot
Meteor hunting isn’t just a treasure hunt, but a scientific expedition that needs exact detail in order to find where the meteorite may have landed.
While we know that it landed somewhere in the north of the island, with the help of trajectory calculations, the prospector needs to identify the meteorite’s ‘dark flight’, which is the part of its fall when it slows to a speed of between 3-4km per second when its bright tail vanishes from sight.
If this can be located, it can narrow down the potential landing site significantly given that it would likely fall soon after its dark flight.
  1. Make sure you have permission before jumping in a field
Given that there’s a lot of farmland across this island, most patches of grass in the countryside are likely to belong to a farmer or group of farmers.
The one thing to be certain of is that if a meteorite falls onto the grounds of someone’s estate, they don’t have the legal right to ownership of a large chunk of space debris, so once permission is sought, legal possession falls to the finder.
It’s probably best not to make them aware of its potential value, however…
  3  Get a good metal detector … and know how to use it
It might seem obvious to run to the nearest store that might sell metal detectors and pick one up to begin a hunt, but it’s much more complicated than that.
Given the complexity of minerals that make up meteorites, it’s simply not possible to just move a metal detector around a field, as would be seen in movies, as a specific type of metal detector is needed to find one.
According to metal detector enthusiasts, it is vital that, when searching for meteorites, the detector’s iron discriminator is switched off to better locate iron-laden meteorites, while gold-prospecting metal detectors are also good at locating the space debris.
  1. Get your rock verified by a mineralogist
Given that it’s likely that many people in Ireland are not experts in minerals, it’s probably safe to say that should someone discover what they believe to be a piece of the recent meteorite crash, it’s best to take it to someone who could actually determine whether it is from terra firma or outer space.
For preliminary tests, however, it might be a good idea to bring a magnet to see whether the rock is magnetic given that the typical meteorite contains between 10-30pc iron.
However, magnetism does not mean it’s a meteorite, rather that it’s increased the likelihood of it being from space.
Likewise, if the sample is ground slightly, does it reveal a metallic silver substance inside? This is one of the tell-tale signs as to whether a rock is just a rock, or an ancient meteorite.
  5  Science over personal gain?
So you’ve discovered a meteorite, congratulations! But while your thoughts might be on where you’re going to install your new swimming pool, make sure to alert organisations, such as Astronomy Ireland, of your find so as they can analyse the sample with the hope of maybe finding something that could prove beneficial to our understanding of the wider universe.
Astronomy Ireland is currently looking for as many reports as possible from eyewitnesses and potential discoverers of the meteorite fragments so take this into account if you are lucky enough to stumble across them.

Serious respiratory infection illness made Charlie Haughey look for his place in Irish history

   

Charles Haughey: The US ambassador complimented the “measured statesmanlike tones” of Haughey during his ard-fheis speech in February1989, which she said were “in strong contrast to the stridently partisan speech of Fine Gael leader Alan Dukes at his party conference”.
A bout of serious illness led to a dramatic change in Charles Haughey’s leadership style as Taoiseach, making him realise it was his “last chance to make his place in Irish history”, US ambassador Margaret Heckler told secretary of state James Baker in a confidential cable in March 1989.
She said the illness made Haughey “determined to rise above his hitherto dominant image as the ultimate political boss”.
In ‘firm control’
A few days later another cable sent in advance of Haughey’s St Patrick’s Day visit to the US described him as being in “firm control” of Irish politics.
“The only cloud on Haughey’s horizon is his health. He has not recovered fully from a severe respiratory infection last fall and will consult a specialist during his Washington trip.”
Haughey had spent time in the intensive care unit of the Mater hospital in October 1988 and the Cork Examinerreported that his heart had stopped but this was vehemently denied by a government spokesman.
The cables were obtained under the US freedom ofinformation Act on foot of a request to the state department for any records from 1989 relating to Charles Haughey. Some records were refused for US national security/foreign policy reasons.
Many of the cables from 1989 deal with the fallout from Haughey’s disastrous decision to call a surprise general election in June which resulted in Fianna Fáil losing seats.
To retain power he formed a coalition with the Progressive Democrats, the first time Fianna Fáil ever participated in a coalition government.
Great survivor
Heckler wrote on July 15th, the day the coalition was formed: “In the end, it would seem, after all, that Haughey, the great survivor of Irish politics, has once againfashioned a victory from defeat . . . In entering a coalition he has put national interests above sectarian party concerns.”
In the cables, Heckler complimented the “measured statesmanlike tones” of Haughey during his ardfheis speech in February1989, which she said were “in strong contrast to the stridently partisan speech of Fine Gael leader Alan Dukes at his party conference”.

HSE managers warned of risks to patients from funding cuts and under staffing

CONFIDENTIAL ‘RISK REGISTER’ SHOWS SCALE OF CHALLENGES FACING HEALTH SERVICE

 
Under pressure from the troika over health costs, the HSE budget has been cut by more than 20 per cent, or €3 billion, since the financial crisis began in 2008.
Health Service Executive managers have warned of high risks to patient safetyas a result of under staffing and spending cuts across key areas of the health service, internal records show.
The executive’s confidential “corporate risk register” provides an insight into the most urgent challenges facing the organisation as it tries to cope with fewer employees and increased demand for services.
The register, seen by The Irish Times, shows the greatest risks facing the executive over the past year. They include:
Harm to patients arising from inadequate delivery of vital health services linked to understaffing;
Funding running out for the nursing home support scheme, causing knock-on problems across the health services;
Unsafe services for children due to a failure to comply with childcare regulations and standards; and
Risk of vaccine-preventable disease, such as measles, occurring due to failure to achieve targets for vaccine uptake.
The troika
Under pressure from the troika over health costs, the HSE budget has been cut by more than 20 per cent, or €3 billion, since the financial crisis began in 2008.
It has also lost more than 11,000 employees over the same period. This year the HSE faces another steep budget cut, although its service plan pledges to deliver the “maximum level of safe services possible”.
However, a detailed breakdown of risks facing individual services across the HSE shows elevated concern over the safety of cancer care for thousands of patients.
Highest risk
One of the highest risk ratings is linked to not having sufficient staff that are “essential to ensure adherence to quality control and quality assurance strategies” across cancer services.
There is also concern that designated cancer centres may fail to meet basic standards or targets for speedy delivery of care due to “fiscal challenges, the recruitment moratorium and other priorities”.
The HSE was not in a position to comment on the register last night, but the documents show it has drafted action plans for all risks identified.
For example, in areas such as patient safety, the register states there is a stronger focus on clinical care through the appointment of clinical directors, healthcare audits andtraining.
The risk register – a common tool across large firms – measures the greatest threats facing an organisation and ranks them in terms of impact and likelihood of occurring.
Fianna Fáil health spokesman Billy Kelleher has described warnings of high risks to patients as a result of understaffing and spending cuts as “frightening but not surprising”.
He said the revelations confirm what his party has been saying “about the high risk to public safety arising from Minister James Reilly’s handling of the health service”.
“[IT] is a damning indictment of Government policy and will cause huge amounts of anxiety amongst patients and their families,” he said.
The TD for Cork north-central called on the Health Minister to “urgently” clarify how these concerns are going to be addressed.
“This will impact on every family in Ireland,” he said. “Minster Reilly needs to urgently change his priorities and focus on frontline services to patients, which he has failed abysmally to do.”

Experienced Seán O’Rourke set to take over Pat Kenny’s slot

  
The veteran RTÉ news and current affairs broadcaster Seán O’Rourke is to be announced as successor to Pat Kenny’s morning radio show.
O’Rourke, who currently presents the RTÉ News at One programme and The Week in Politics on RTÉ television, will replace Kenny who announced his shock departure from the national broadcaster, where he has worked for over four decades, last week.
The move is set to create an intensive radio rivalry between two of the industry’s greatest luminaries in current affairs and whose shows will air at the same time.
A source revealed the decision was made at a meeting in a Monaghan hotel yesterday morning, and involved several key Montrose executives including director general Noel Curran and head of news and current affairs Kevin Bakhurst.
The announcement is due to be made on RTÉ Radio 1 on the Marian Finucane Show today where he will be interviewed by Aine Lawlor.
O’Rourke is renowned for his presence on the national broadcaster’s flagship radio news programme and has a reputation as a formidable interviewer, particularly of politicians.
His appointment will see him leave that slot for the first time in nearly two decades having started there in 1995.
The 54-year-old, from Portlaoise, began his career at the Connacht Tribune, following up with stints at the Sunday Press and Irish Press as a sports journalist, feature writer and political correspondent.
He has been with RTÉ news and current affairs since 1989 as an editor and presenter. He has also reported extensively from abroad.
It is unclear if, at all, the move will affect his other role as presenter of The Week in Politics which airs every Sunday night on RTÉ television.
Kenny made the surprise announcement last week in what was widely considered an industry coup for Newstalk Radio, his new employer who said he would be on air from September 2nd next.
He said he was “relishing the challenge ahead and looking forward to a new chapter”, particularly in the world of independent broadcasting.
Last night, betting on Kenny’s replacement appeared to have been suspended on Paddy PowerKenny worked with the State broadcaster for the last 41 years before joining the Denis O’Brien controlled Newstalk where he will anchor the station’s prime time slot.

Thousands of AIB customers subject to loan credit errors

    

Thousands of AIB customers may have been turned down for loans because the bank sent incorrect customer data to the Irish Credit Bureau, according to reports.

The Irish Independent today reports that as many as 12,000 customers may have been incorrectly identified as having poor track records for repaying loans.
It’s believed the errors occurred over a period of six years.
Last year thousands of AIB customers learned that incorrect records were kept on their loan histories, as overdue loans were marked down as being a 4 weeks late, when in fact they may have been only overdue a week.

Harvard School study says breakfast every day can keep the doctor away

   
The well known benefits of eating a good breakfast are endless, from its metabolism-boosting powers to staving off mid-morning hunger pangs.

But recent research added a new factor to the mix, when it was found that men who regularly skipped breakfast had a 27% higher risk of heart attack or death from coronary heart disease than those who routinely ate a morning meal. 

The study, by Harvard School of Public Health (HSPH) in the USA, is the first of its kind to indicate a direct link between the two, and found that breakfast-skippers were generally hungrier later in the day and ate more food at night, perhaps leading to metabolic changes and heart disease.
It followed 26,902 men aged 45-82 over a 16-year period and even after accounting for diet, physical activity, smoking and other lifestyle factors, the association between skipping breakfast and heart disease persisted.
Lead author Dr Leah Cahill, a research fellow at HSPH, suggests: “Skipping breakfast may lead to one or more risk factors, including obesity, high blood pressure, high cholesterol and diabetes, which may in turn lead to a heart attack over time.”
Cahill says the research team expects the results to apply to women as well, and they currently have a similar study with females under way.
Daniel McCartney, a lecturer in dietetics at DIT says: “Breakfast kick-starts the metabolism and wakes up the body.
“A high-fibre cereal will also slow absorption of sugar from the gut. Insoluble fibre — found in cereals such as Weetabix and All Bran and in bananas — can fill you until lunch time.
Dietitian Victoria Taylor suggests wholegrain toast or cereals like porridge with low-fat milk are a good way to start the day.
“Try a sliced banana or dried fruit on top and you’ll be on your way to five-a-day before you’ve even left the house,” she adds.
“A healthy and filling breakfast can make that mid-morning biscuit less tempting, as well as giving you another opportunity to widen the variety of foods in your diet.”
Healthy options include the following: nPorridge made with semi-skimmed milk topped with a selection of dried fruits. Oats are a good source of insoluble fibre.
* Muesli, fresh fruit and low-fat yoghurt. Added fruit counts towards your five-a-day, and low-fat yoghurt provides calcium and protein.
* Wholegrain breakfast cereal with semi-skimmed milk. Many cereals are fortified with vitamins and minerals.
* Boiled egg with wholemeal toast and low-fat spread. Eggs are a good source of protein, minerals and vitamins A, D and B2. Wholemeal bread contains B vitamins, vitamin E, fibre and a range of minerals.

Perseid meteor shower will help astronomers get a better view of space

  
As sky-watchers marvel at the beauty of the annual Perseid meteor shower — set to peak late Sunday and early Monday — astronomers will be thanking their shooting stars for another reason. Airborne pollution from vaporized meteors is proving crucial for the nextgeneration of super-sharp snapshots of exotic moons and distant galaxies.
Pollution of any kind is usually bad NEWS for telescopes, which thrive on clear skies. But shooting stars — flaming bits of debris from comets — leave behind traces of an element astronomers are harnessing to sharpen the focus of their telescopes.
That element is sodium. Traces of it waft in a band encircling the Earth about 55 miles above ground. American astronomer Vesto Slipher of Arizona discovered this sodium layer in 1929, but only recently have astronomers found a use for it — by zapping it with lasers.
“We can excite the sodium [with a laser] and make an artificial star,” said Chad Trujillo of the Gemini Observatory, a multinational consortium that operates telescopes in Hawaii and Chile.
Sensors watching these artificial “guide stars” see them twinkle — the effect of atmospheric turbulence. This wavy air usually renders distant targets fuzzy. But by watching the guide star, sophisticated computers on the ground can calculate the turbulence and send that data to the telescope. Sophisticated mirrors in the telescope then deform hundreds of times per second to compensate for the wavy air.
It’s like adding a pair of glasses with rapidly changing prescriptions to the telescope.
This technique — adaptive optics — has been called the biggest advance in ground-based astronomy since Galileo’s first telescope some 400 years ago. “You get better resolution from the ground than you can from space,” Trujillo said.
Astronomers began to tinker with crude adaptive optics in the 1950s. But the technology did not mature until the military became interested in artificial guide stars in the 1980s, said Claire Max, director of the center for adaptive optics at the University of California Observatories. “At that point, it was all highly classified,” said Max, who was working at the Lawrence Livermore National Laboratory at the time. The military wanted to image Soviet satellites, but Max had other ideas: “I said, ‘Astronomical objects move a lot slower that satellites, so I think it will be a great idea for astronomy.’ ”
Max and her colleagues pushed the Defense Department to declassify the technology, which it did in the early 1990s. “There was a famous meeting of the American Astronomical Society when the veil was lifted and everybody heard what the Air Force was doing,” Max said.
The first laser guide-star system came online at the Lick Observatory in 1995. Max used the system to bring Saturn’s moon Titan into focus. A hazy blob sharpened into view, allowing study of the storms raging in the moon’s methane atmosphere.
Earlier this year, the most sophisticated laser guide-star system to date came online at the Gemini South telescope in Chile. The $25 million system sharpens the telescope’s 25-foot mirror onto a wider swath of sky than ever before.
“We’re looking deep into the cores of colliding galaxies now and watching black holes. It’s really fun,” Max said. “You couldn’t see any of the detail if you looked without these systems.”
It took five years to build the Gemini guide-star system, but the experience will aid the next generation of giant telescopes. Laser guide stars will be crucial for maximizing their views.
