Our solar system's journey around the center of the Milky Way takes it through varying galactic environments, and one may have had a lasting impact on Earth's climate, according to a new study.

An ambitious new survey by the Hubble Space Telescope offers the first bird's-eye view of all known dwarf galaxies orbiting the Andromeda galaxy. The data suggests Andromeda had a chaotic past unlike anything scientists expected.

In world-first observations, the James Webb Space Telescope is watching two distant alien planets "spilling their guts into space" as they rapidly disintegrate — and scientists are elated at what they've found.

"I'll always remember the first time I saw those iridescent clouds and was sure at first it was some color artifact."

"There is reason to have confidence in upward trajectory of the space economy."

Astronomers have used a continent-sized radio telescope to find the largest black hole jet ever observed in the early universe.

Black holes can actively regulate the material they consume, using powerful jets of gas blasted into space, according to a new study. It suggests many such cosmic beasts effectively "cook" their own meals.

A doorbell camera recorded a rare video of the moment a meteorite fell outside a home.

The first black hole that astronomers observed "turning off" just turned back on, releasing jets of hot gas into the cosmos.

The innermost Earth-like planet in the famous TRAPPIST-1 system might be capable of supporting a thick atmosphere after all, according to new research.

On Christmas Eve, NASA's Parker Solar Probe flew closer to the sun than any human-made object ever — a stunning technological feat that scientists liken to the historic Apollo moon landing in 1969. Now, we know it survived.

A display of auroras is expected to light up the skies on Christmas Day, thanks to a powerful M8.9 solar flare enroute to Earth.

Astronomers have discovered a pair of young stars near the supermassive black hole at the heart of our galaxy. Studying them can offer a rare glimpse into how stars can endure — at least briefly — the immense gravity exerted by such cosmic behemoths.

The odd atmosphere of a fledgling exoplanet is causing astronomers to question leading theories of how planets form.

Astronomers analyzing archival images from JWST have discovered an unexpectedly vast population of the smallest asteroids ever seen in the asteroid belt between Mars and Jupiter.

Data from China's Zhurong rover has revealed what appears to be an ancient shoreline streaking through Mars' northern hemisphere.

Fast radio bursts — powerful and poorly understood cosmic eruptions — tend to occur in massive galaxies that host long-dead stars known as magnetars, a new study suggests.

A new species of tardigrades with thousands of genes that become more active when exposed to radiation could help in devising better protection for astronauts on long missions.

A fresh analysis of decades-old X-ray black hole jet data has revealed bright, lumpy features with mysterious speed changes.

India is eyeing a 2028 launch for its Chandrayaan-4 moon sample-return mission, followed by an uncrewed lunar lander and rover in collaboration with Japan.

A rare nova explosion will soon bring a "new star" to the night sky, and scientists are excited.

Astronomers have gotten the first-ever detailed views of turbulent activity on a star other than our own sun.

The source of a supposed alien broadcast that made researchers go "Wow!" may instead have been the result of a remarkably rare cosmic event, a new study suggests.

Scientists are trying to decipher what drove the recent dramatic cooling of the tropical Atlantic, but so far few clues have emerged. "We are still scratching our heads as to what's actually happening," the researchers said.
