Milky Way image reveals detail of a billion stars

More than one billion stars in the Milky Way are visible together in detail for the first time in an image captured by an international team of astronomers. Scientists created the color picture by combining infrared light images from telescopes in the Northern and Southern Hemispheres. Large structures of the Milky Way Galaxy, such as gas and dust clouds where stars have formed and died, can be seen in the image. Nick Cross from the University of Edinburgh, Scotland, presented the new work March 29 at the National Astronomy Meeting in Manchester, United Kingdom.

The picture represents part of a 10-year project involving scientists from the United Kingdom, Europe, and Chile who gathered data from the two telescopes. The information has been processed and archived by teams at the universities of Edinburgh and Cambridge, which have made it available to astronomers around the world for further studies.

Archived information from the project — known as the VISTA Data Flow System — is expected to enable scientists to carry out groundbreaking research in future years without the need to generate further data.

The image shows the plane of the Milky Way Galaxy, which is often described as looking like two fried eggs back to back, with a flat disk in the middle. Earth is close to the edge of this disk, and the image shows a cross-section through the disk as seen from Earth’s perspective.

It combines data from the UKIDSS/GPS sky survey taken by the United Kingdom Infrared Telescope in Hawaii with the VVV survey from the VISTA telescope in Chile.

Astronomers used infrared radiation instead of visible light to enable them to see through much of the dust in the Milky Way and record details of the center of the galaxy.

“This incredible image gives us a new perspective of our galaxy, and illustrates the far-reaching discoveries we can make from large sky surveys,” said Cross. “Having data processed, archived, and published by dedicated teams leaves other scientists free to concentrate on using the data, and is a very cost-effective way to do astronomy.”

Too bad that the autors claim all the glory and that only a handfull of them do include their co-workers on their project merits.No one but no-one should ever claim a report or a discovery as being their own for it is all the merit of the collaborator's that is all too often being mis-appropriated by the lone signature and is that because I am an astronomer and I know a lot morew than youdo_puzzle.

Hopefully, there won't be any "more-equal, less-equal" arguments. As long as some are willing to mill the wheat so that the Simon Cowell's can make their technicolor Parisienne baguettes........ And then to "equate" the situation to economic wisdom, is effectively saying that as long as there are those to make the books, there will be those to read them, and make sense of them, for the rest of us. Why aren't the processors and archivists and publishers able to "use" the data themselves? Isn't that how the WISE and Kepler, et al., data are treated? Overall, I think Cross' view is a bit like playing "Where's Waldo" with the accomplishment of the surveys, and somewhat diminishes the contributions of the "other" scientists involved in the surveys. I do believe that the astronomers involved in the tedium of sky surveys already realize that they, personally, will never be able to view all the data gathered. Their kicks are had by the discoveries of other astronomers from the harvest. A bit like the tribe surviving the winter based on your personal farming prowess; feels pretty good. So, instead of pointing out the economic benefits of the corroboration to which he is intrinsically second-party, Mr. Cross should be thanking the predecessor astronomers for their wisdom of foresight to embark on such sky surveys, despite their tedium and immensity. It is a blessing of the greatest serendipity that processing power has come into existence in the nick of time to accommodate this influx of discovery data in the recent two decades. Maybe he should, also, thank Bill Gates and the Jobs Estate.
