More hypervelocity stars are jetting out of the galaxy
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.

The authors of today’s paper find out just what kind of star formation history lies in the Milky Way’s next meal: The Small Magellanic Cloud. After all, they say you are what you eat.
What kind of star is orbiting around a millisecond pulsar and where did it come from?
In this article, the authors measure the stellar mass-metallicity relation for star forming galaxies ranging to z~2.3. They find that mass-metallicity relationship for these galaxies evolves with time and also that it flattens at late times.
Type Ia Supernovae are extensively used in astronomy research, but the progenitors of these massive explosions are still not well understood. This paper discusses new evidence that there are two distinct populations of type Ia supernovae, and that they originate from different stellar populations.
Using massive gravitational lenses can help us study the evolution of galaxies over unprecedented time scales.
