We tend to think of comets as ancient relics of our own solar system, but interstellar comet 3I/ATLAS carried 30 times more heavy hydrogen than any comet formed around our Sun, a chemical fingerprint pointing to a birthplace so cold and so old it may pred
Most comets are treated as leftovers from a local story. They formed with the planets, spent billions of years in the cold outskirts of the Solar Syst...

The interstellar comet 3I/ATLAS is now thought to be 10 to 12 billion years old, meaning it was already drifting between the stars for more than twice the age of the Sun before our solar system existed.
The newest estimate for interstellar comet 3I/ATLAS changes the scale of the object. It is not just older than the solar system. If the interpretation...

In July 2025, the ATLAS sky survey in Chile spotted a faint comet racing through the solar system at roughly 130,000 miles per hour — and follow-up orbit calculations quickly showed it was not bound to the Sun at all, but had arrived from interstellar spa
On July 1, 2025, the ATLAS survey telescope in Rio Hurtado, Chile, reported a faint moving object to the Minor Planet Center. At first, it looked like...
