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.

A "guest star," briefly seen in 1181, was created by colliding dead stars, according to new simulations that may finally solve an 800-year-old cosmic mystery.

The physicist César Lattes, who is honored today (July 11) in a Google Doodle, is famous across Latin America for his discovery of the pion — a subatomic particle produced by shockwaves from exploding stars.
