Few spectacles in space are as phenomenal as supernovae, but a "superkilonova" may give them a run for their money. This type of cosmic outburst is thought to arise when a supernova cascades into a ...

Caltech astronomer Mansi Kasliwal and her colleagues were not expecting to chase a mystery that blurred the line between a supernova and a kilonova. Yet that is where the evidence has led after an ...

Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

New research describes how a kilonova explosion triggered by colliding neutron stars could eradicate life on Earth for thousands of years. Thankfully, the odds are incredibly low. When you purchase ...

(Nanowerk News) When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron.
