Astronomers watched as the supergiant WOH G64 reshaped itself into a different type of star.
Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.
The ancient stellar death took place when the universe was a mere 730 million years old.
The aging pair of stars swing by one another once every 190 years, producing four spirals of dust.
A new discovery offers fresh insights into the life cycle of massive stars and their imminent death.
A 600-year-old stellar event described in cryptic language finally gets a scientific ID.
Dubbed Teleios, the unusually symmetrical space object is puzzling astronomers with its near-perfect shape and mysterious origin.
The nearby T Coronae Borealis system could still explode any day now, but calculations suggest the next best chance for fireworks is later this year.
The rare nova explosion—once it happens—will be so bright that you'll be able to spot it without a telescope.
The circumgalactic medium, a vast gaseous halo surrounding galaxies, could be crucial to the evolution of star-forming galaxies like our own.
The star offers hints at how huge stars shed gas and dim towards the ends of their lives.
The supernova that caused the nebula was recorded by Japanese and Chinese astronomers in the 12th century. Now, we know exactly what the aftermath looks like.
A stellar binary could explain the red supergiant's pattern of intermittent dimming, but not everyone is convinced.
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.
