Stellar Science

Most of the lights we see in the night sky with our naked eye are stars, and stars have always been at the heart of astronomy. We use telescopes to peer through dusty gas to see young stars forming, and we watch in awe as old stars explode in supernovae. Stars die to become white dwarfs, neutron stars, pulsars, and black holes, but the ways these metamorphoses work still perplex astronomers.

Keep up to date on the latest discoveries in our study of the stars. From new classes of variables to the brilliant smashup of two neutron stars, we bring you news on how stars are born, live, and die in the universe.

Which of Kepler’s Stars Flare?

The habitability of distant exoplanets is dependent upon many factors — one of which is the activity of their host stars. To learn about which stars are most likely to flare, a recent study examines tens of thousands of stellar flares observed by Kepler. Need for a Broader Sample Most of our understanding of what…

The Star That Wouldn’t Die

Observations of a stellar explosion that refused to fade away have astronomers scratching their heads. What created the blast — and could it explain massive black holes?

When a Star and a Binary Meet

What happens in the extreme environments of globular clusters when a star and a binary system meet? A team of scientists has new ideas about how these objects can deform, change their paths, spiral around each other, and merge.
