A massive comet trail may have caused climate upheaval on Earth more than 12,000 years ago, sparking the Younger Dryas.

NASA’s Hubble Space Telescope has captured its most detailed image yet of interstellar comet 3I/ATLAS. The rare comet is ...

NASA's Hubble Space Telescope got an up-close look at a headline-grabbing object known as 3I/ATLAS that has wandered into ...

Of course, 3I/ATLAS is no ordinary comet. Discovered on July 1, 2025 by the Asteroid Terrestrial-impact Last Alert System ...

The comet is hurtling our way at 130,000 mph, but will veer closer to Mars than Earth, keeping a safe distance from both.

Discovered last month by a telescope in Chile, the comet known as 3I-Atlas is only the third known interstellar object to pass our way.

The shower is courtesy of Comet 109P/Swift-Tuttle, a 26 kilometer (16 mile) wide comet that takes 133 years to orbit the Sun.

The latest observations suggest the comet could be as wide as 5.6 kilometres, and at least 320 metres. Further observations ...

The comet’s orbit is huge, extending out to about 55,000 times the Earth-sun distance—87 percent of a light-year and well out into the Oort Cloud of icy objects that surrounds our sun.

A Harvard astrophysicist has suggested that a newly discovered comet passing through our solar system might be an alien spacecraft in disguise. The claim by Professor Avi Loeb has split opinion in the ...

Comet 3I/ATLAS was first identified by the Asteroid Terrestrial-impact Last Alert System (ATLAS), a global network of four robotic telescopes located in Hawaii, Chile, and South Africa. ATLAS ...
