Astronomers have watched the growth of a jet fueled by a shredded star.
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.
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.
Astronomers have discovered three more red, dusty objects near the Milky Way’s central black hole that could be merged stars.
Two new studies — one by a group of high school students — are investigating the strange environment around Tabby's Star.
New observations have helped astronomers identify the source of a 2,000-year-old supernova explosion. But this blast, and the neutron star that created it, seem to have a curious history that defies explanation.
Astronomers have discovered a pulsar that comes with its own magnifying glass — courtesy of its brown dwarf companion that’s being torn to shreds.
This week in astronomy news: Researchers discover the first completely cloud-free exoplanet and a star-forming cloud reveals its structure through vibrations.
The gravitational-wave detection last year of a neutron star merger has revealed details on neutron star structure, ruling out exotic quark matter in the objects’ cores.
Astronomers have found the gamma-ray-emitting remains of three exploded stars, and the remnants might reveal the origin of cosmic rays.
You may have seen recent news about NGC 1052–DF2, a galaxy that was discovered to have little or no dark matter. Now, a new study explores what NGC 1052–DF2 does have: an enigmatic population of unusually large and luminous globular clusters.
The discovery of a runaway star in the Small Magellanic Cloud suggests that runaway stars are a common phenomenon in the universe.
Astronomers have discovered 72 fast and furious explosions, possibly supernovae blasts cloaked in cocoons of ejected gas.
Astronomers have discovered a newborn neutron star in a rare pairing with an old red giant companion.
New ALMA observations reveal a fiber-like structures within a longer, well-studied filament. These fibers contain the seeds of future stars.
Got any plans in 46 million years? If not, you should keep an eye out for PSR J1946+2052 around that time — this upcoming merger of two neutron stars promises to be an exciting show!
It turns out that neutron stars — not black holes — power at least some ultraluminous X-ray sources.
Supermassive black holes en route to merger have strange dynamics in their gas disks. Astronomers have spotted the most distant spectroscopically confirmed supernova. And NSF decides the fate of the Arecibo Observatory.
In 2016 an amateur astronomer was testing his camera — and captured the first flash of a supernova.
Astronomers presenting at the winter American Astronomical Society meeting caution that the features often pointed to as evidence of growing natal planets could form on their own.
A repeating fast radio burst first detected in 2012 likely formed within a potent magnetic field — opening up the ambiguity of what caused the mysterious burst.
A new study found more massive stars than expected in an intensely star-forming region. The results beg the question whether the process of star formation really is universal.
A new theory of the solar system’s formation suggests that it formed within the shell of a wind-blown bubble surrounding a dead star.
New data on Boyajian's Star show that dust — not an alien megastructure — is probably the cause of this star's mysterious behavior.
