Saturn has finally joined the solar system's other giant planets in possessing a Trojan asteroid, but it may have stolen it. The bouncing asteroid seems to have originated in the Kuiper belt.

The first "black hole triple" system, consisting of a black hole hungrily feeding on a companion star orbited by a more distant star, hints at a gentle formation process without supernova explosions.

The James Webb Space Telescope has discovered lonely quasars in the early universe, with "empty larders" that defy theories surrounding their growth to monster sizes.

A map of gravity wells or "basins of attraction" in the local universe may resemble a Taylor Swift outfit, but they define the largest structure in the universe, the last line of your cosmic address.

Space.com talks to artist and author Martin Vargic, who is turning exoplanets into stunning and intricate art.

"Killer electrons" stashed in radiation belts around Earth could be dislodged by lightning to create a game of "cosmic pinball" that influences space weather around our planet.

The Hunter's Moon rose on Thursday (Oct. 17), becoming the biggest and brightest full moon of the year and wowing skywatchers around the globe with a spooky pre-Halloween show.

'Photosynthetic habitable zones' could exist beneath radiation-filtering ice on Mars, offering scientists another region in which to hunt for alien life.

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

U.S. company Vast has unveiled Haven-2, its proposed commercial successor to the soon-to-be-retired International Space Station.

The "first page" of an incredible cosmic atlas being built by the Euclid Space Telescope has been released. The millions of stars and galaxies represent just 1% of the 3D map the mission will create.

NASA's Chandra X-ray space telescope has spotted the cosmic serial killer that, like Michael Myers, is back for a sequel, killing a star and attacking a second star with its remains.

Astronomers using the James Webb Space Telescope had to race against time to image a young exoplanet before it disappeared for a decade.

'If we can understand how these materials came to be on Earth, it might give us clues to how life originated here, and how it might emerge elsewhere.'

Using the James Webb Space Telescope, astronomers have found a "first of its kind" world, an exoplanet that is twice the size of Earth and has an atmosphere packed with steam.

A powerful geomagnetic storm illuminated auroras that lit the skies over Earth on Thursday (Oct. 9) after X 2 solar flare that erupted from the sunspot AR 3848 on Tuesday (Oct. 8) evening.

NASA's Hubble Space Telescope and New Horizons Pluto probe have teamed up to image the ice giant Uranus, which will help inform future direct imaging of exoplanets.

There's too much antimatter in cosmic rays, showers of charged particles that pelt Earth. Could this be explained by annihilating dark matter? If so, does it point to the existence of WIMPs?

Using the Gaia space telescope, astronomers have observed 55 massive stars ejected from their home star cluster in the Large Magellanic Cloud at speeds equivalent to 80 times the speed of sound.

Astronomers have discovered the most distant and, thus, earliest strongly rotating galaxy ever seen that is well-organized rather than chaotic and messy, challenging our theories of cosmic evolution.

"Venus is certainly a good example of one extremity of the greenhouse effect run amok."

The James Webb Space Telescope has taken an intricate look at how pancakes of gas and dust feed infant stars and help them grow before influencing the birth of planets.

The James Webb Space Telescope has spotted the earliest supermassive black hole-driven quasar wind ever seen, pushing away matter at 6,000 times the speed of sound and killing its host galaxy.

Using NASA's exoplanet-hunting spacecraft, TESS, astronomers and citizen scientists have discovered a record-breaking system of three tightly bound stars that could fit between the sun and Mercury.

The James Webb Space Telescope has observed a distant cosmic explosion that erupted in the early universe called "supernova Hope" that could help resolve lingering "Hubble trouble."
