A Beginner’s Guide to Predicting Supernovae

Astrobites reports on an updated neutrino detector that may be able to alert us to impending supernovae hours in advance.

Artist's impression of a young planetary system

A new study loosens the constraints on planet formation, suggesting that most protoplanetary disks stick around for at least 5 million years.

multiwavelength image of the galactic center region

How did the stars at the center of our galaxy attain their curious arrangement? A new theory suggests that a shredded star paved the way for new stars to form in a narrow disk.

A Supernova Hits a Cosmic Speed Bump

In 2021, astronomers saw a star explode, then watched as its remains strangely changed colors. A recent study suggests an explanation for this behavior: the remnants hit a speed bump.
