We have more Betelbuddy news, and the little companion star to Betelgeuse is turning out to be an oddball.
Astronomers didn't think these kinds of stars still existed—until now.
Astronomers have confirmed the existence of a companion star in a tight orbit around Betelgeuse, resolving a long-standing mystery about the star’s varying brightness.
Astronomers found an exceptionally rare star system that formed through an elusive cosmic phenomenon.
A nearby star system, teetering on the edge of a spectacular explosion, promises a rare cosmic show that’ll be visible to the naked eye.
Data from a recent stellar explosion showed a mathematical discrepancy, possibly providing rare evidence of a black hole forming right before our very eyes.
Located one billion light-years away, the star—thought dead—appears to be going through a revival, with scientists spotting energetic flares.
Astronomers developed the world's first AI system that can automatically detect, identify, and classify supernovae. It could save scientists precious time.
A luminous oval approximately 163,000 light-years distant poses a formidable challenge for the state-of-the-art space observatory.
The burnt-out star has one side composed of hydrogen and the other composed of helium. Astronomers have never seen anything like it.
Dust reservoirs spewed by two stellar deaths show how stars might be born.
Astronomers argue that a recent study forecasting a relatively imminent stellar explosion misses the mark.
13.5-billion-year-old clouds are poor in iron, suggesting they precede the dissemination of heavier elements.
The white dwarf is the dead core of a star that burned out a billion years ago.
The flying observatory expanded what we know about astrophysics and planetary science, but NASA could no longer justify the project.
A rare stellar death may have formed a rock that eventually landed in Egypt.
The rare objects may be the result of unusual stellar mergers.
Some supergiant stars experience significant internal changes before going supernovae, according to new and unprecedented astronomical observations.
A white dwarf star is flinging material from its companion as it spins a record-breaking speed.
Our star has an expiration date. But how can we be sure it's not any time soon?
