Puzzles from an Ensemble of Young Planets
New observations of a young hot Jupiter — likely surrounded by a set of three gas-giant siblings — is raising questions about the formation of giant planets.

New simulations provide a stunning view of a collapsing star, revealing behavior that’s only evident in three-dimensional modeling.
Two Explosions with Similar Quirks
Could a burst of gamma rays from 2015 help us to understand the strange emission from the merging neutron stars observed last year?
Some Like it Hot
Astrobites explores how gas giants form via core accretion. Can this formation process reveal secrets about the planet long after the accretion is over?
What Should We Assume?
Astronomers need to rely on assumptions sometimes. Astrobites reports on how we make sure these assumptions don’t get us into trouble.
How to Turn Off a Galaxy’s Star Formation
New ALMA observations provide a closer look at how a galaxy may be shutting down its star formation.
Oscillations in the Eye of the Bull
Red giant Aldebaran is one of the most recognizable stars in the night sky. What can historical and modern radial velocity data tell us about this star and the planet that orbits it?
Investigating Our Expanding Universe
The universe is expanding — but we’re still not sure how quickly! A new study investigates whether we can resolve the conflict between measurements of its expansion rate.
The Tortoise and the Star
Astrobites reports on why we need to better understand the bubbling, broiling surfaces of stars in order to interpret tortoise-speed velocity shifts in starlight.
