A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
A new technique gives astronomers a closer look at what makes some stellar carnage so incredibly luminous.
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.
Researchers have mapped the magnetic field in Supernova 1987A, shedding light on how stellar blasts act as particle accelerators.
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.
