Artist's impression of a supernova. By ESO/M. Kornmesser/Wikimedia Commons, CC BY My hypothesis is that remnants of a supernova – an exploding star – had an impact on the Earth’s past climate, causing ...

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

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

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

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 ...

Astronomers detected radio waves from a rare exploding star, revealing what happens in the final years before a massive star ...

Measuring distances across the universe is much more challenging than measuring distances on Earth. Is a brighter star closer to Earth than another, or is it just emitting more light? To make ...

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 ...

What is your supernova hypothesis? My hypothesis is that remnants of a supernova—an exploding star —had an impact on Earth's past climate, causing global cooling, between 3 million and 2.6 million ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years ...
