Gaia satellite data revealed the galaxy, which has avoided detection until now, thanks to its extremely low density and hiding place behind the shroud of the Milky Way’s disk.

Only a small number of hypervelocity stars have ever been discovered. Now ESA’s Gaia mission has revealed 20 more.

Analysis of data from the Gaia satellite shows a powerful burst of star formation – a stellar baby boom – in our Milky Way galaxy 2 to 3 billion years ago. This single burst might have created half the stars in the galaxy’s flat disk.

The Andromeda galaxy is the nearest large spiral to our Milky Way. Astronomers have suspected for some time it will eventually collide with our Milky Way. Now – thanks to the Gaia satellite – they know more.

We think of globular clusters as being scattered far from the galaxy’s central regions, in the great spherical halo of our Milky Way. But astronomers are finding them much closer to the galactic center.

Last week, citizen scientists with Zooniverse’s Exoplanet Exoplorers announced K2-288Bb – a type of exoplanet considered rare so far. The finding might shed new light on how planets form.

Astronomers are “99 percent confident” that this exoplanet is real and not a false detection. The planet for Barnard’s star – 2nd closest star system to our sun – appears to be a cold super-Earth.

Astronomers found a snail-shaped substructure of stars in our larger Milky Way galaxy. It indicates the Milky Way is still enduring the effects of a near-collision that set millions of stars moving like ripples on a pond.

Is something unpredicted going on in the depths of space?

A new study uses data from ESA’s Gaia satellite to give the first systematic estimate of how often passing stars nudge comets from the Oort Cloud and send them plunging toward the inner solar system.
