It's the last clearly observed supernova in the Milky Way, Gassel said.

NASA’s Chandra Observatory reveals a 25-year time-lapse of Kepler’s Supernova Remnant. Glowing debris expands at different ...

Kepler's supernova remnant is extremely exciting for astronomers – a rare example of a supernova for which we have a clear kick-off timeline, dating back more than 400 years. It's also just 20,000 ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...

Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.

Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever. Using the European Southern ...

In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

In 1987, earthbound observers saw a star explode in the nearby dwarf galaxy called the Large Magellanic Cloud. Astronomers eagerly studied this supernova–the closest seen in the past 300 years–and ...

For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but they've never seen visual evidence of this happening. That just changed.
