Scientists have observed that some of Neptune's Trojan asteroids are deep red, possibly revealing what asteroids may have been like in the early days of the solar system.

NASA's James Webb Space Telescope measured the temperature of the Earth-like planet TRAPPIST-1b and found that it is too hot for humans and likely has no atmosphere.

A river of hazy red light stretched across the night sky over Denmark after the most powerful solar storm to hit Earth for six years slammed into our planet. The rare phenomenon is not an aurora.

A bizarre object called "the Cow" is the flattest explosion ever detected, and the first example of a rare phenomenon called a fast blue optical transient (FBOT).

The 'Hawking radiation' emitted by black holes may be able to carry information after all, a new solution to Stephen Hawking's famous paradox suggests.

An object once thought to be a radio galaxy is actually an active black hole that changed angles to point directly at Earth, new research suggests.

Astronomers used gravitational lensing and supercomputers to identify the colossal black hole, which is among the largest ever found.

Scientists are taking a closer look at the afterglow left by the brightest gamma-ray burst ever recorded, and what they see doesn't fit with any theoretical models.

Scientists detected water trapped inside glass spherules on the moon after analyzing soil samples brought back by China's Chang'e-5 mission.

STEVE was spotted across the U.S. and in parts of the U.K. after the most powerful solar storm to hit Earth for six years smashed into our planet.

Scientists watched as two stars slowed in their orbits around black holes, concluding it was the result of "drag" generated by dark matter.

A severe geomagnetic storm from a huge hole in the sun's corona caused a massive disturbance in Earth's magnetic field. The surprise event sparked auroras as far south as Alabama and northern California.

Potentially hazardous asteroids, or potentially hazardous objects, are large space rocks that orbit closely to Earth and could cause widespread damage to our planet.

Watch live online as the dwarf planet Ceres swoops in front of the 'grand design' spiral galaxy Messier 100 this weekend.

Using the James Webb Space Telescope, scientists observed a massive dust storm in the atmosphere of VHS 1256 b, a 'super-Jupiter' exoplanet located 40 light-years from Earth.

What's the biggest black hole in the universe, and is there a limit to how big black holes can get?

An enormous coronal hole wider than 20 Earths has opened in the sun's atmosphere, and NOAA experts predict a moderate geomagnetic storm Friday (March 24) as a result.

A massive solar tornado recently towered over the sun's north pole for three days. The plasma twister was created by a rapidly rotating magnetic field.

Within a month of the Big Bang, a second cosmic explosion may have given the universe its invisible dark matter, new research suggests.
