"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs."

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied."

The James Webb Space Telescope has spotted one of the earliest and most distant supernovas, marking the death of a stellar monster 20 times the mass of the sun.

Pluto may have got romantic to capture its largest moon, colliding and engaging in a passionate but icy 10 hour kiss with Charon billions of years ago.

A rare group of aligned, star-birthing dwarf galaxies resemble a cosmic string of pearls.

A "missing link" black hole in Omega Centauri is still missing. What appeared to be an intermediate-mass black hole was a cluster of stellar-mass black holes.

What knocked this black hole over onto its side? It's a cosmic "whodunnit" that NASA scientists using the Hubble and Chandra space telescopes are trying to solve.

The James Webb Space Telescope has caught a napping monster black hole in the early universe. The cosmic giant is slumbering after a massive meal like a reveler on Christmas Day.

Scientists at CERN's ALICE detector are replicating conditions found during the Big Bang, attempting to get to the bottom of how matter came to dominate over antimatter.

An asteroid hitting a neutron star could release enough energy to power humanity for 100 million years, more than enough to explain fast radio bursts.

"We would have loved to find that Venus was once a planet much closer to our own, so it’s kind of sad in a way to find out that it wasn't."

"Even years after the Arecibo Observatory's collapse, its data continues to unlock critical information that can advance our understanding of the galaxy."

Was alien life in "hot water" on Mars billions of years ago? New evidence from the Martian meteorite "Black Beauty" suggests so.

A 3D map of our cosmic neighborhood has revealed hot and cold regions as well as an "escape tunnel" from our local bubble.

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision that created the smallest black hole ever seen.

A 6-mile-think shell of methane ice on Saturn's moon Titan could assist in the hunt for life signs arising from this moon's vast subsurface ocean.

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.

"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.

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 earliest strongly rotating galaxy ever seen that's well-organized rather than chaotic, challenging theories of cosmic evolution.

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.

NASA has turned off one of Voyager 2's science instruments as power conservation becomes crucial for the interstellar exploring spacecraft located 12.8 billion miles from home.

Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins.

The James Webb Space Telescope has taken things to the extreme, studying the outer edge of our own galaxy, the Milky Way and producing a stunning new image.
