Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

The most distant supernova ever detected has turned one of the weirdest theories ever proposed into the leading explanation for how our universe works, scientists say. The exploding star was spotted ...

An international team of researchers has discovered a way to use observations at ultraviolet (UV) wavelengths to uncover characteristics about superluminous supernovae previously impossible to ...

"Remarkable" findings from Yonsei University cast doubt on 'dark energy' theory and claim there is "no evidence" of an ...

Astronomers observe Type II supernova SN 2024bch behaving differently, with energy from Bowen fluorescence rather than ejecta interaction, challenging models of stellar death and high-energy neutrino ...

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 ...

Light from a supernova explosion in the nearby starburst galaxy M82 is reverberating off a huge dust cloud in interstellar space. The supernova, called SN 2014J, occurred at the upper right of M82, ...

When a massive star runs out of nuclear fuel at the end of its life, it collapses — the star’s dense core falls in on itself, squeezing protons and electrons together to make the neutrons that form an ...

Hubble images reveal an expanding shell of light from a supernova explosion sweeping through interstellar space three years after the stellar blast was discovered. The "echoing" light looks like a ...

An international team of researchers has discovered a way to use UV light from superluminous supernovae to uncover its explosion mechanism, and used it to identify Gaia16apd as a shock-interacting ...
