![]() ![]() I don’t think that’s anything that is, quite frankly, among most people, in dispute anymore,” press secretary Robert Gibbs told reporters this week.īut Republicans on Capitol Hill say the revelations deserve a congressional investigation. ![]() “Several thousand scientists have come to the conclusion that climate change is happening. The White House has dismissed the British e-mails as irrelevant. He said he was unfamiliar with the British controversy and couldn’t say whether NASA was susceptible to the same challenges to its data. “It’s just a process you have to go through where you have to collect data that’s responsive.” “We’re collecting the information and will respond with all the responsive relevant information to all of his requests,” Mr. Horner’s request, though he couldn’t say why they have taken so long. Mark Hess, public affairs director for the Goddard Space Flight Center which runs the GISS laboratory, said they are working on Mr. Horner suspects the same sort of data-shaving has happened at NASA’s Goddard Institute for Space Studies (GISS), another leading global warming research center. The center has also had to acknowledge in response to a freedom of information request under British law that it tossed out much of the raw data that it used to draw up the temperature models that have underpinned much of the science behind global warming. The center’s chief has stepped down pending an investigation into the e-mails. His fight mirrors one in Europe that has sprung up over the the University of East Anglia’s Climatic Research Unit in the UK after thousands of e-mails from the center were obtained and appear to show researchers shaving their data to make it conform to their expectation, and show efforts to try to drive global warming skeptics out of the conversation. He said he’s given the agency until the end of the year to comply or else he’ll sue to compel the information’s release. Horner, a noted global warming skeptic and author of The Politically Incorrect Guide to Global Warming and Environmentalism, wants a look at the data and the discussions that went into those changes. ![]() The field of view is about 3.2 x 3.1 arcminutes. The total exposure times were 1360 s, 200 s and 364 s, respectively. The colour image was created from exposures through a blue filter (F435W, coloured blue), a red filter (F625W, coloured green) and a filter that passes near-infrared light (F814W coloured red). This image was taken using the Wide Field Channel of Hubble’s Advanced Camera for Surveys. Messier 12 lies about 23 000 light-years away in the constellation of Ophiuchus (The Serpent Bearer). It seems that the serenity of this view of Messier 12 is misleading and the object has had a violent and disturbed past. They speculate that nearly one million low-mass stars have been ripped away from Messier 12 as the globular has passed through the densest regions of the Milky Way during its orbit around the galactic centre. In a recent study, astronomers used the European Southern Observatory’s Very Large Telescope at Cerro Paranal, Chile, to measure the brightness and colours of more than 16 000 of the globular’s 200 000 stars. It is thought that such X-ray binaries form from very close encounters between stars in crowded regions, such as globular clusters, and even though Messier 12 is fairly diffuse by globular cluster standards, such X-ray sources have been spotted there.Īstronomers have also discovered that Messier 12 is home to far fewer low-mass stars than was previously expected ( eso0604). But the cramped living quarters in these clusters also makes them home to exotic binary star systems where two stars are locked in tight orbits around each other and matter from one is gobbled up by its companion, releasing X-rays. ![]() The high concentration of stars within globular clusters, like Messier 12, shown here in an image from the NASA/ESA Hubble Space Telescope, makes them beautiful photographic targets. ![]()
