Astronomers have found signs that the small icy world Chiron, orbiting between Saturn and Uranus, may be forming a new ring system in near-real time.

New telescope images show that the interstellar comet 3I/ATLAS is shooting a giant jet of gas and dust toward the sun. This is normal behavior for comets, an expert told Live Science.

Researchers discovered a hidden 185,000 light-year "bridge" of gas between two distant galaxies, which are also trailed by a 1.6 million light-year galactic tail — the largest of its kind ever seen.

The newly discovered "twilight" asteroid, 2025 SC79, was obscured by the sun's glare until an astronomer pointed the Dark Energy Camera at it, highlighting the potential dangers of unseen asteroids.

Using the James Webb Space Telescope, scientists have charted billions of years of galactic evolution, finding that galaxies near the dawn of time were much more chaotic than they are today.

An astrophotographer snapped a stunning shot of Comet Lemmon's flowing tail getting shredded by a strong gust of solar wind, just three days before it reaches its closest point to Earth.

A photographer snapped a striking shot of Comet Lemmon streaking over Scotland as the night sky unexpectedly filled up with a technicolor mix of vibrant auroras.

Comet Lemmon (C/2025 A6) makes its closest approach to Earth on Oct. 21, about 24 hours after the fainter Comet SWAN (C/2025 R2) does the same. Here's how, where and when to see them both.

For the first time ever, astronomers revealed the birthplace of an energetic jet blasted by a newborn star using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
