The positions and reconstructed orbits of 20 high-velocity stars, represented on top of an artistic view of the Milky Way Galaxy.
The seven stars shown in red are sprinting away from the Galaxy and could be traveling fast enough to eventually escape its gravity.
Surprisingly, the study revealed also thirteen stars, shown in orange, that are racing towards the Milky Way: these could be stars
from another galaxy, zooming right through our own. Image credit: NASA / ESA / Hubble / Marchetti et al.

The Milky Way contains over a hundred billion stars. Most are located in a disc with a dense, bulging center; the rest are spread out in a much larger spherical halo.

Stars circle around the Milky Way at hundreds of miles per second, and their motions contain a wealth of information about the past history of the Galaxy.

The fastest class of stars in our Galaxy are called hypervelocity stars, which are thought to start their life near the Galactic center to be later flung towards the edge of the Milky Way via interactions with the black hole.

Only a small number of hypervelocity stars have ever been discovered, and Gaia’s second data release provides a unique opportunity to look for more of them.

e.g. they could be made out of chocolate.
