the European Space Agency (ESA) said.<\/p>\n<p>&#8220;It&#8217;s the Swiss Army knife of astrophysics\u2014there is not a single astronomer who does not use its data, directly or indirectly,&#8221; said Francois Mignard, a member of the Gaia team.<\/p>\n<p>Some of the map&#8217;s new insights are close to home, such as a catalog of more than 156,000 asteroids in our Solar System &#8220;whose orbits the instrument has calculated with incomparable precision,&#8221; Mignard said.<\/p>\n<p>But Gaia also sees beyond the Milky Way, spotting 2.9 million other galaxies as well as 1.9 million quasars\u2014the stunningly bright hearts of galaxies powered by supermassive black holes.<\/p>\n<p>The Gaia spacecraft is nestled in a strategically positioned orbit 1.5 million kilometers (937,000 miles) from Earth, where it has been watching the skies since it was launched by the ESA in 2013.<\/p>\n<p><b>&#8216;Beautiful melting pot of stars&#8217;<\/b><\/p>\n<p>&#8220;Gaia scans the sky and picks up everything it sees,&#8221; said astronomer Misha Haywood of the Paris Observatory.<\/p>\n<p>But it can still only detect around one percent of the stars in the Milky Way, which is about 100,000 light years across.<\/p>\n<p>The probe is equipped with two telescopes as well as a billion-pixel camera, which captures images sharp enough to gauge the diameter of a human hair at a distance of 1,000 kilometers (620 miles).<\/p>\n<p>It also has a range of other instruments that allow it to not just map the stars, but measure their movements, chemical compositions and ages.<\/p>\n<p>&#8220;It provides a global observation of the positions of anything that moves in the sky, for the first time,&#8221; Haywood said, adding that before Gaia &#8220;we had a really restricted view of the galaxy&#8221;.<\/p>\n<p>It also reveals the huge array of differences between stars.<\/p>\n<p>&#8220;Our galaxy is a beautiful melting pot of stars,&#8221; said Gaia member Alejandra Recio-Blanco. <\/p>\n<p>&#8220;This diversity is extremely important, because it tells us the story of our galaxy&#8217;s formation,&#8221; he said. <\/p>\n<p>&#8220;It also clearly shows that our Sun, and we, all belong to an ever-changing system, formed thanks to the assembly of stars and gas of different origins.&#8221;<\/p>\n<p><b>Surprise starquakes<\/b><\/p>\n<p>The observation of &#8220;starquakes&#8221;, massive vibrations that change the shape of the distant stars, was &#8220;one of the most surprising discoveries coming out of the new data&#8221;, the ESA said.<\/p>\n<p>Gaia was not built to observe starquakes but still detected the strange phenomenon on thousands of stars, including some that should not have any\u2014at least according to our current understanding of the universe.<\/p>\n<p>&#8220;Gaia is opening a gold mine for &#8216;asteroseismology&#8217; of massive stars,&#8221; said Gaia member Conny Aerts.<\/p>\n<p>Around 50 scientific papers were published alongside the new data, with many more expected in the coming years. Gaia&#8217;s observations have fuelled thousands of studies since its first dataset was released in 2016.<\/p>\n<p>The second dataset in 2018 allowed astronomers to show that the Milky Way merged with another galaxy in a violent collision around 10 billion years ago.<\/p>\n<p>The torrent of raw data is combed through by a team of 450 European scientists and software engineers using six supercomputers as well as &#8220;human-driven algorithms&#8221; as part of the Data Processing and Analysis Consortium, Mignard said.<\/p>\n<p>&#8220;Without this processing group, there is no mission,&#8221; he added, because every day Gaia produces 700 million star positions and 150 million photometric measurements.<\/p>\n<p>It took the team five years to deliver the latest data, which was observed from 2014 to 2017. <\/p>\n<p>&#8220;We can&#8217;t wait for the astronomy community to dive into our new data to find out even more about our galaxy and its surroundings than we could&#8217;ve imagined,&#8221; ESA&#8217;s Gaia project scientist Timo Prusti said.<\/p>\n<p>The final data set will be released in 2030, after Gaia finishes its mission surveying the skies in 2025.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Gaia sees strange stars in most detailed Milky Way survey to date\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Gaia in-depth: <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cosmos.esa.int\/web\/gaia\/data-release-3\">www.cosmos.esa.int\/web\/gaia\/data-release-3<\/a><br \/>\nGaia images: <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Search?SearchText=gaia&amp;result_type=images\">www.esa.int\/ESA_Multimedia\/Sea \u2026 a&amp;result_type=images<\/a><\/p>\n<\/div>\n<p class=\"article-main__note mt-4\">\n                                                \u00a9 2022 AFP<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Milky Way&#8217;s secrets revealed by massive space probe map (2022, June 13)<br \/>\n                                                 retrieved 13 June 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-06-milky-secrets-revealed-massive-space.html<\/p>\n<p>                                            This document is subject to copyright.
