WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

In December 2024, the ATLAS astronomical survey detected a distant flash of light. It was a supernova, the explosive death of a massive star, located far, far away, roughly a billion light-years away.

CHAMPAIGN, Ill. — The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign. Rather ...

A cosmic mystery surrounding the universe's most dazzling explosions, superluminous supernovas, appears to have been solved by scientists studying a colossal stellar event a billion light-years from ...

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially ...

As astronomers have learned more about the tumultuous and unforgiving nature of the universe, we've been comforted to know that there are no stars in our cosmic backyard threatening to go supernova.

All giant stars—those that are at least eight times larger than our sun—are destined to undergo a “core collapse.” As the star exhausts its hydrogen and helium fuel it begins to fuse heavier elements ...

I was exploding with excitement to ask my friend Guy Worthey about supernovas. He’s an astronomer at Washington State University. He told me a supernova is a very energetic explosion in space. There ...

Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...
