Researchers have combined 15 years' worth of radio data to peer through the cone of a high-energy jet and unravel the magnetic mysteries of a "blazar" billions of light-years from Earth. The new findings also shed light on the origin of elusive "ghost particles."

The ghostly light, which was triggered by a rocket reentry, sailed across the night sky as skywatchers across the U.S. looked up to see "shooting stars" streak across the heavens. However, experts are confused over which spacecraft is responsible.

The recent discovery of a potential gas giant circling the nearby star Alpha Centauri A has led to speculation that it may be orbited in turn by a habitable moon that could support life, just like in the "Avatar" movies.

A surprising new paper suggests that the universe's expected lifespan is just 33 billion years, and that the cosmos will start dying in less than a third of that time. However, this is only one possible theory.

Astronomers believe they have spotted an elusive intermediate-mass black hole shredding a distant star, and they have re-created the stellar murder in a stunning new animation.

Eris-1, the first rocket fully built by an Australian company, crashed back to Earth 14 seconds after taking off from a spaceport in Queensland. It was the country's first orbital launch attempt since 1971.

Detailed photos from the newly operational Vera C. Rubin Observatory have revealed that the recently discovered interstellar object 3I/ATLAS is roughly 7 miles wide, making it the largest of its kind ever seen.

A controversial new paper questions whether the interstellar object 3I/ATLAS is a potentially dangerous alien probe, similar to claims made about 'Oumuamua. But experts have called it "nonsense".

New photos, including a striking technicolor timelapse, show off the newly discovered interstellar object 3I/ATLAS as it shoots toward us through the solar system.

The largest known Martian meteorite, NWA 16788, has been sold at auction for $5.3 million. The hefty chunk of the Red Planet, which weighs 54 pounds, could help unravel new secrets about Mars — if it's allowed to be studied.

Astrophotographers have snapped stunning shots of a giant shapeshifting solar prominence, dubbed "The Beast," which appeared over the sun's northeastern limb on July 12 and rained impossibly fast fire over our home star.

Debris released from the asteroid Dimorphos during NASA's DART mission has a higher momentum and less random distribution than expected, which "changes the physics we need to consider when planning these types of missions," researchers say.

New simulations have narrowed down where the newly discovered interstellar comet 3I/ATLAS likely came from, revealing it could be more than 3 billion years older than the solar system.

Astronomers have been given the rare opportunity to study an extrasolar object after the recent discovery of the interstellar comet 3I/ATLAS. Experts tell Live Science how they are planning to observe the cosmic visitor.

Astronomers have spotted a new interstellar object — the third of its kind ever seen — shooting towards us through the solar system. Here's everything you need to know about 3I/ATLAS.
