ESA’s Gaia Satellite Spots High-Velocity Stars Flying between Galaxies

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.

Astronomers using data from ESA’s star mapping Gaia mission to look for hypervelocity stars being kicked out of our Milky Way Galaxy were surprised to find stars instead sprinting inwards — perhaps from another galaxy. 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...

Neutron stars are the smallest, densest stars in the Universe. True to their name, neutron stars are composed almost entirely of neutrons. Duer et al suggest that some properties of neutron stars may be influenced not only by their multitude of densely packed neutrons, but also by a substantially smaller fraction of protons -- positively charged particles that make up just 5% of a neutron star. This is an illustration of a neutron star. Image credit: Casey Reed, Penn State University.
