A Northwestern University-led team of astronomers used NASA’s James Webb Space Telescope to discover a former star that ...

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos. Researchers have now been able to study some of a supernova's progression by ...

NASA’s James Webb Space Telescope captured the first published detection of a supernova progenitor in galaxy NGC 1637, revealing a red supergiant star before explosion.

For the very first time, astronomers have captured a radio signal emitted by a very specific type of stellar explosion. This unprecedented observation offers us a glimpse into the final moments of ...

Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

Astronomers say one of the universe’s largest stars has dramatically changed since 2014, possibly entering a rare final phase that could end in a spectacular supernova explosion.

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National ...

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

Astronomers report a supergiant star in the Andromeda Galaxy, M31-2014-DS1, collapsed directly into a black hole without a supernova, confirming predictions of failed stellar explosions.

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
