supernova

Astronomers have taken a superdetailed, zoomed-in photo of the Large Magellanic Cloud's "behemoth star." The stunning image, which is the first of its kind from outside the Milky Way, shows that the giant star is right on the edge of going supernova.

New research reports the most powerful cosmic rays ever detected. Because the rays lose energy as they travel through space, their detection at high energies means they are likely coming from sources relatively close to Earth.

An artist's rendering of a black hole

Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.

A new animated map sheds light on the superhot "zombie star" at the heart of a nebula leftover from a distant supernova witnessed by astronomers in 1181. The remains of the stellar explosion are unusually wonky and are still exploding at a constant speed.

The James Webb Space Telescope has zoomed in on an ancient supernova, revealing fresh evidence that a crisis in cosmology called the Hubble tension isn't going anywhere soon.

A Hawaii telescope just captured a sun-like star's glowing gas layers as it expands. The resulting butterfly-shaped nebula is a sight to behold.

The T Coronae Borealis nova will soon burst into life above our heads for the first time in 78 years.

Citizen scientists have discovered what may be a brown dwarf racing through the cosmos at around 1.2 million miles per hour. Now astronomers want to know what launched it.

While headlines around the world claimed that ancient galaxies discovered by the James Webb Space Telescope were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.
