Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume ...

In the vastness of space lies an incredible truth: we are made of stardust. This video tells the awe-inspiring story of how ...

We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

Cuttlefish use visual tricks to avoid being eaten. New research shows how they deploy similar camouflage to bamboozle their prey.

At 6,500 light-years away in the constellation Taurus, the Crab Nebula has illuminated the night sky since its supernova explosion in 1054. This celestial phenomenon was observed by astronomers ...

The Crab Nebula is the remnant of a supernova that appeared in 1054. "Historical records, including Chinese accounts, describe an unusually bright star appearing in the sky," said the KU researcher.

The Crab Nebula features a neutron star at its center that has formed into a 12-mile-wide pulsar pinwheeling electromagnetic radiation across the cosmos.

NASA's top five images from space include AG Carinae, the Crab Nebula with X-rays, the Andromeda galaxy in infrared, and Cassiopeia, a supernova remnant showing elemental gases.

"The Crab Nebula lives up to a tradition in astronomy: The nearest, brightest, and best-studied objects tend to be bizarre." In July 1054, astronomers in China documented a "guest star" in the sky ...

Images from the James Webb Space Telescope and the Chandra X-ray Observatory have been combined to reveal how the Crab Nebula's neutron star is changing.

The time lapses show the famous Crab Nebula, a strikingly beautiful nebula located 6,500 light-years away, and Cassiopeia A, the leftover remnant of an exploded star located 11,000 light-years away.

Almost 1,000 years ago, on July 4, 1054 AD, Chinese astronomers documented a new, very bright star that suddenly appeared in their sky. The star was so bright it was visible even during the ...
