Do star clusters form all at once or over several generations? A team of astronomers finds an answer among the spinning stars of an amateur favorite, the Wild Duck Cluster.
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.
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.
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.
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
Revised data changed expectations for a star pair that was supposed to merge in 2022.
The first "fast radio burst" detected by the Canadian CHIME radio telescope is a tantalizing hint of what’s to come.
Faint echoes of light illuminate what really happened during the Great Eruption of the super-star Eta Carinae.
Astronomers have discovered a hiccup in stellar luminosities that may point to a new understanding of stellar structure.
A team of scientists says we now have an answer to one of the biggest mysteries of GW170817: after the neutron stars collided, what object was formed?
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.
