Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...

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 ...

Stargazers, rejoice: There's a new supernova in the night sky. Though not visible with the naked eye, the supernova is bright enough to see through a small telescope, according to Sky and Telescope ...

In an unprecedented event, there are THREE active supernovae simultaneously seen exploding in a galaxy right now! While two supernovae seen at the same time in the same galaxy has happened before, to ...

SN 2023ixf is a new Type II supernova discovered in May 2023 by amateur astronomer Kōichi Itagaki of Yamagata, Japan shortly after its progenitor, or origin star, exploded. Located about 20 million ...

Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

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 ...

An international team of astronomers has conducted optical and near-infrared observations of a supernova designated SN ...

Every so often, a mysterious so-called "guest star" appears in the sky, often far outstripping its cousins in brightness. Astronomers and stargazers have known about such events since at least 185 AD ...

A Type II supernova has been documented for the first time. This space achievement is a big deal since it can help astronauts and other experts to understand dying stars better. This NASA image shows ...

New observations of a recently exploded star are confirming supercomputer model predictions made at Caltech that the deaths of stellar giants are lopsided affairs in which debris and the stars’ cores ...

NASA announced that a nearby star has exploded, and telescopes worldwide will be turning in its direction to witness the celestial display. And if you want to check it out for yourself, you’re in luck ...
