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.

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

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.

The largest component of the universe is something we know almost nothing about. The best and most accurate observations that cosmologists have gathered over decades show that all the matter around us ...

Supernovae, the explosive deaths of stars, are some of the universe's biggest bursts of energy and light. When they erupt, one supernova can shine even brighter than an entire galaxy. It's a fitting ...

An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...

Researchers from the University of Colorado Boulder have found that the rings in Earth's ancient trees may hold evidence detailing the death of massive stars, known as supernovae, throughout space.

Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth's history. An analysis of the frequency of supernova explosions in the Milky Way, led by ...

Few things have more influence in the cosmos than the most violent celestial death we know of: the supernova. These stellar finales are so extreme that not only do they shape the space directly around ...

The final stage of cataclysmic explosions of dying massive stars, called supernovae, could pack an up to six times bigger punch on the surrounding interstellar gas with the help of cosmic rays, ...
