The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

Astronomer Giovanni Cassini observed Jupiter's 'Permanent Spot' in 1665, but new research suggests it's a different vortex from today's Great Red Spot.

The James Webb telescope has spotted a peculiar group of baby stars firing enormous jets into space at nearly the exact same angle. The discovery could hold new insights into how stars are born.

New research offers the most precise measurements yet of pulsating Cepheid stars, which could reveal new clues about the immense size and scale of our universe.

The "Blaze Star" T Coronae Borealis is expected to erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.

The time of the annual summer solstice will be the earliest it's been for centuries and will continue to creep forward every leap year until 2100. But why?

Astronomers may be watching a supermassive black hole "waking up" from a long slumber for the first time ever. The researchers think the black hole may have gotten its hands on a glut of new material to devour, causing an uptick in brightness.

NASA's Perseverance rover spotted a bizarrely light-toned boulder on Mars, the likes of which have never been seen before.

Two superluminous quasars, or active black holes at the centers of large galaxies, were found just 900 million years after the Big Bang — the earliest detection of a pair of merging quasars ever seen.

A new analysis of inexplicably young stars orbiting extremely close to the Milky Way's black hole heart reveals that they orbit around the gigantic structure in a surprisingly organized way, similar to swarming insects like bees.
