The latest data outlet from the European Space Agency ’s Gaia lookout just dropped , and it ’s a monumental one : the spacecraft has identify half a million stars in a nearby cluster , most 400 gravitational lense , and the orbits of some 156,000 - odd asteroid .
This bombardment of science is part of the observatory ’s third data release , the first part of which came out inJune 2022 . Gaia has been in blank since December 2013 , and is positioned in a neighborhood called L2 , the same area that theWebb Space Telescopecalls home .
“ With the young data we can study the bunch ’s bodily structure , how the constituent stars are distributed , how they ’re moving , and more , creating a complete large - graduated table map of Omega Centauri , ” said Alexey Mints , a phallus of the Gaia Collaboration and the Leibniz - Institute for Astrophysics Potsdam , in an ESA dismission . “ It ’s using Gaia to its full potential – we ’ve deployed this amazing cosmic tool at maximal power . ”

The half a million newly spot maven were just a handful of the Frederick North - of-1.8 - million on which data was collected in the recent set of observations . The stars are in Omega Centauri , the largest globular bunch seeable from Earth , a roughly 150 - light - class - wide group of lead that is 17,000 light - years from Earth .
The new pick out stars are fainter than many of those previously detected ; Gaia has now seen 10 sentence more stars in the clump ’s core , and stars 15 times fainter , according to ESA .
The Gaia release is so monumental that five research written document comprise its data : one paperdescribes the half - million new spy stars , aseconddetails the variability of the asterisk ; athirdunpacks the chiliad of asteroids and their orbits ; afourthscrutinizes two mapped interstellar set composed of gun and dust ; and afifthtakes a foresighted looking at the hundreds of potential gravitative lens system spotted by the observatory .

Gaia also observed over 380 gravitative lenses , or objects in space that bend and focus light from the more distant macrocosm . Gravitational lenses allow astronomers to peer deeper into outer space , tosee ancient galaxiesand evenclues about the nature of dark matter .
“ Thanks to Gaia , we ’ve found that some of the aim we see are n’t plainly stars , even though they expect like them , ” tell Christine Ducourant , an astrophysicist at the Laboratoire d’Astrophysique de Bordeaux and a extremity of the collaboration , in the ESA release . “ They ’re actually really distant lensed quasars – extremely bright , energetic galactic cores power by sinister holes . ”
Fifty of the 381 quasar candidates are extremely likely to be the real deal , Ducourant added , an exciting prospect for astrophysicist hop tobetter read ancient participating galactic nuclei .
find clusters like Omega Centauri can yield different kinds of utilitarian information , including details of how sensation age and how coltsfoot evolve . Gaia ’s fourth data release will admit observations of eight more area of space thickly populated by mavin . That departure will likely not come until 2026,according to ESA . The final data point release planned for the mission is its 5th , which will not come before the end of 2030 .
