Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

Venus (mag. -3.9, in Gemini – the Twins), soon to reach superior solar conjunction, becomes visible 20 degrees above the ...

The James Webb Space Telescope is weighing in on a longstanding debate over why we don’t see more of the most massive red supergiant stars go supernova. NASA/ESA/CSA/Northrop Grumman In recent years, ...

Betelgeuse is one of the closest stars to Earth, at a distance of only 650 light-years away. This makes Betelgeuse a fan-favorite with professional and amateur astronomers alike. Betelgeuse is a red ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

WASHINGTON — A supernova, the explosive death of a star, is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron star or black hole. But ...

According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here's how they plan to crack the case.
