Neutral particles accelerated to incredible speeds could be used to investigate powerful solar storms, according to a new study.

NASA's Chandra X-ray Observatory spied a massive "H" structure half the size of our entire galaxy made of blazing hot gas spewing from a distant supermassive black hole.

The two protesters burst from their cocoons of gas and dust in Lupus 3, a vast stellar nursery located about 500 light-years from Earth.

The Hubble Space Telescope captured a stunning image of a distant star cluster that could help us better understand how such clusters evolve and even reveal the elusive black holes at their hearts.

Observing a powerful feeding black hole in X-ray light has allowed astronomers to peer into the inner workings of what is the brightest quasar seen in the last 9 billion years of cosmic history.

Skywatchers can see the lunar face half illuminated by the sun at the weekend when the moon enters the first quarter phase of its 29.5-day cycle on Saturday, May 27.

Astronomers are snooping on the Milky Way's galactic neighbors to gain insights about the ancient galaxies being viewed by the James Webb Space Telescope.

NASA's Lucy spacecraft has altered its course ahead of visiting its first asteroid target in Nov. 2023 on its way to become the first probe to visit the Trojan asteroids that orbit Jupiter.

A newly discovered supernova can be watched as it develops in real-time online and for free. The livestream will begin at 6:30 p.m. EDT (2230 GMT) on Friday, May 26.

The second set of NASA's TROPICS cubesats launched on Thursday night (May 25), completing the agency's hurricane-studying miniconstellation.

Virgin Galactic has released a video introducing the public to the pilots who fly the company's VSS Unity space plane, which is gearing up for its final test flight.

Skywatchers can watch the moon get close to the solar system's hottest planet Venus on Tuesday (May 23) thanks to a free telescope livestream.

NASA's CAPSTONE cubesat has captured its first image of the moon, snapping the lunar north pole as it tested navigation technology similar to GPS used around Earth.

NASA's Juno mission made its 51st flyby of the gas giant planet Jupiter and its moons, catching stunning images of Io, the most volcanic world in the solar system.

Stunning images tell the story of the launch and landing of the Falcon 9 rocket that carried the Ax-2 crew to space on Sunday (May 21).

The Ax-2 crew, including three first-time astronauts and the first Saudi woman to reach space, shared their reactions after reaching space on their way to the International Space Station.

The Ax-2 mission is set to lift off on Sunday (May 21) atop a SpaceX Falcon 9 rocket, sending the first private mission commanded by a woman, and the first female Saudi astronaut, to space.

Scientists have created a rotating disk of plasma in the lab that mimics the accretion disks that surround black holes, gradually feeding them and facilitating their growth.

A flavor of black hole known as a blazar often exhibits behavior that defies explanation. A new study of 106 supermassive black holes may shed some light.

A young NASA mission spotted strange movements of X-rays in the supernova remnant known as Cassiopeia A, which may include an extremely dense and small star.

Earth probably won't get hit by an asteroid at least 0.6 miles (1 kilometers) wide in the next 1,000 years, a new study finds.

NASA's InSight mission spotted a marsquake that probed the thick Mars crust and confirmed why the north and south of the Red Planet are so different.

Astronomers have made the first detection of a supernova in radio waves, finding that an exploding white dwarf star was feeding from a companion star like a cosmic vampire before it blew.

The new BlackGEM array will hunt for black hole mergers and neutron star collisions, cataclysmic events that generate ripples in space-time known as gravitational waves.
