Speeding White Dwarfs May Point to Past Explosions

A recent study has discovered three of the fastest stars — white dwarfs — known in the Milky Way. But these stars may be more than just speeders — they might also be evidence of how Type Ia supernovae occur.

Two Explosions with Similar Quirks

High-energy radiation released during the merger of two neutron stars last year has left astronomers puzzled. Could a burst of gamma rays from 2015 help us to piece together a coherent picture of both explosions?

A New Look at the Solar Corona

The hot, tenuous solar corona is visible during a total solar eclipse, and astronomers have long studied the structure and dynamics of the ghostly coronal streamers. Now, a special observing campaign has allowed us to see the corona in unprecedented detail.

Surprise Discovery of a 14-Year-Old Supernova

Much of today’s astronomy happens via methodical searches, but sometimes serendipitous discoveries still surprise us. Such is the case with the transient CGS2004A, a possible supernova recently detected in a galaxy nearly 50 million light-years away.

Seen at Last: A Superfast Jet Streams Away from Neutron-star Smashup

A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.

Too Many Massive Stars in Universe's Youngest Galaxies

A new method of measuring star formation in the earliest galaxies finds that they’re producing more massive stars than expected — a result that could affect our understanding of how galaxies grow their stars.

A Massive Neutron Star with a Two-Faced Companion

How massive can a neutron star get? In a recent study, scientists may have identified the most massive neutron star yet — by leveraging observations of its highly irradiated companion.
