How to Spot a Disrupted Galactic Satellite
It’s hard to spot satellites of our galaxy that have been torn apart during their orbits! But, using a clever technique, a team of scientists has recently found one.

Despite equipment failure in 2013, the Kepler spacecraft is still discovering planet candidates! A recent study reports on the K2 mission’s first year of observations.
This beautiful series of snapshots from a simulation shows what happens when two stars in a binary system become enclosed in the same stellar envelope.
Tidal disruption events occur when a star passes a little too close to a supermassive black hole, getting torn apart in the process. Does this happen more frequently in an unusual type of galaxy?
Where should we hunt for potentially habitable planets? A recent study has generated a catalog of the habitable zones around nearby stars.
What generated the radiation that reionized our universe? The recent discovery of multiple distant galaxies offers evidence for how this process occurred.
What if Type Ia supernovae aren’t as consistent as we thought? A recent study investigates the dependence of these “standard candles” on the metallicity of their environment.
A pair of red-giant twins may be a key to weighing stars using starquakes in their interiors.
A recent study shows that WD 1145+017, a white dwarf surrounded by disintegrating planetary bodies, has evolved dramatically since its discovery last year.
Big news: LIGO has detected its first gravitational-wave signal! What does this mean for black-hole astrophysics?
If LIGO finds gravitational waves, could JWST be used in the future to follow up on detections of some compact-object mergers?
Images of two powerful solar prominence eruptions have helped astronomers model how these eruptions travel away from the Sun.
