Reinterpreting Planet-Driven Gaps
The stunning gaps and rings of protoplanetary disks may be driven by embedded planets — but a new study suggests caution when interpreting these models.
Testing Collapsars as the Key to Heavy Elements
How do we get the heavy elements in our universe? New evidence suggests collapsing stars may not be the answer.
Catching Radio Signals from Colliding Objects
Models say the merger of two compact objects could come with a sudden flash of radio emission. Can we spot it?
Exomoon, or No Exomoon?
Is Kepler-1625b-i an actual moon in another solar system? Or just an artifact of data reduction?

Building a Pair of Blue Stragglers
A new study looks at one way unusually bright and blue stars might form in clusters … with a little help from a friend.
Do Active Galactic Nuclei Help or Hurt Life?
A new study suggests radiation from the centers of active galaxies could play an important role in the formation and survival of life on some planets.
Plasma Processes in Mars’s Shadow
NASA’s MAVEN mission has given us an in-depth look at the atmosphere of our neighboring planet. What’s happening to the atmospheric plasma during Martian nighttime?
