One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

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

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S ...

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 ...

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 ...

SN Ares might be the most exciting one. The star exploded when the universe was about one-third of its current age.

Dark energy, a force responsible for the expansion of the universe, is mostly unknown. But this month, researchers released a new survey meant to unpack its mysteries. Dark energy, a force responsible ...

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 ...

The visible universe is a big place. Like, really, really big — some 93 billion lightyears across (via Futurism). To put that in perspective, that's like running 25 billion back-to-back marathons, and ...

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 ...

Supernova destroying planet, illustration. A rocky planet lies in the wake of its star, which has just gone supernova. The explosion shatters the planet. A complete census of massive stars in our part ...
