In our galaxy, a supernova explodes about once or twice each century. But historical astronomical records show that the last ...

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, but defining the rate of that expansion is challenging. The rate of ...

Astronomers have captured the first radio signals from a rare supernova, revealing intense activity in a star’s final years before it exploded.

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and ...

The signals provide astronomers with a look into the life, and death, of a massive star exploding into a supernova.

Astronomers evaluate how the Vera C. Rubin Observatory can detect and localize the next Milky Way core-collapse supernova using neutrino alerts and optical surveys.

Astronomers used the James Webb Space Telescope and gravitational lensing to observe SN Eos, an ordinary supernova from the ...

A team of astronomers using the James Webb Space Telescope (JWST) has detected a remarkably distant Type II supernova that ...

An extremely early Type II supernova explosion, named after the Titan goddess of dawn in Greek mythology, occurred just 1 ...

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 ...

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 ...
