The European Space Agency's Gaia telescope revealed half a million newfound stars, and detailed the orbits of over 150,000 asteroids.
New data from the Gaia space telescope are being called a cosmic "goldmine," including never-seen-before stars, 380 gravity-lensed quasars, and the orbits of over 150,000 asteroids.
Planets grow in rotating disks of dust and gas around forming stars, some of which can subsequently collide in giant impacts after the gas component is removed from the disk1–3. Monitoring programmes with the warm Spitzer mission have recorded substantial and rapid changes in mid-infrared output for several stars, interpreted as variations in the surface area of warm, dusty material ejected by planetary-scale collisions and heated by the central star: for example, NGC 2354–ID8 (refs. 4,5), HD 166191 (ref. 6) and V488 Persei7. Here we report combined observations of the ...
