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.
LIGO’s neutron-star smashup might not have been a typical short gamma-ray burst. If true, the detection points toward a new class of gamma-ray bursts — but the jury is still out.
This week's roundup of astro news brings us a polar-orbiting planet, a novel way to measure stellar masses, and ginormous convective bubbles on a distant star.
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…
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
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?
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
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.
The exoplanet-hunting Kepler satellite has long monitored thousands of stars, but the brightest ones have largely remained out of its reach — until now.
Thermonuclear power sets off a type of stellar explosion known as a classical nova. Now, new research explains the mechanisms that cause these blasts to light up.
Astronomers and historians pinpoint the source of a 15th-century classical nova. It’s currently regathering strength.
Researchers have constructed a detailed view of the surface of red supergiant star Antares, revealing a chaotic atmosphere powered by mechanisms that are still poorly understood.
A peculiar white dwarf could be what’s left after a failed supernova explosion.
Solar astronomers may have finally detected gravity waves in our star’s core, revealing that the Sun’s central region rotates about four times faster than the outer layers.
