A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

"The most likely explanation for the dimming is a brown dwarf – an object heavier than a planet but lighter than a star – surrounded by a vast and dense ring system." ...

The first solar eclipse of the year is almost here, but very few people will see it. Tuesday’s annular solar eclipse, known as a “ring of fire,” will only be visible in Antarctica.

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like ...

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s that theorized that when a star underwent direct collapse, it would leave ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

"This provides observational evidence of black hole formation in real time, suggests that many black holes may form without ...

In 2014, a NASA telescope observed as the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed ...

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

A neutrino with almost unimaginable energy slammed into Earth in early 2023, carrying roughly 220 petaelectronvolts, far beyond anything human machines can produce. The event, tagged KM3-230213A, has ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole ...
