When Gaia meets Hubble: accurate proper motions for faint stars
A powerful new tool combines data from Gaia and the Hubble Space Telescope and accurately measures how stars move on the plane of the sky. Find out how it’s done in today’s Astrobite!

What might be lurking just beyond our solar system? Get a sneak preview of Dr. Jackie Faherty’s views ahead of her talk, “Our Dynamic Solar Neighborhood”, at #AAS236!
This astrobite looking at a star that is moving so fast, it can escape our galaxy. But is everything as it seems?
There she blows! A detective case tracking the motion of material ejected from a star to figure out when the star exploded.
Palladino et al. find 13 new hypervelocity star candidates in the galaxy and find they probably do not originate from the center of the galaxy.
HST measurements of stellar proper motions in M31 reveal that the Andromeda galaxy is in radial (head-on collision) orbit towards the Milky Way. The huge strike will happen 4 billion years from now according to the simulations. It will likely affect also the environment of the Sun and the location of the solar system.
