Massive eruption from icy volcanic comet detected in solar system

A bizarre, volcanic comet has violently erupted, spewing out more than 1 million tons of gas, ice and the potential building blocks of life into the solar system. The volatile comet, known as 29P/Schwassmann-Wachmann (29P), is around 37 miles (60 kilometers) wide and takes around 14.9 years to orbit the...

Rare green comet not seen since the Stone Age will zoom overhead tonight. Here's how to watch.

On Feb. 1, a comet called C/2022 E3 (ZTF) will pass by Earth for the first time in 50,000 years, meaning the last time it cruised by our planet, Homo sapiens were still sharing the planet with Neanderthals. And according to calculations from astronomers, the comet will never come back....

Bright new comet discovered zooming toward the sun could outshine the stars next year

A newly discovered comet may appear as bright as a star in the night sky by fall 2024. The comet, known as C/2023 A3 (Tsuchinshan-ATLAS), was first noted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope project in South Africa on Feb. 22, according to the Minor Planet Center....

'Missing link' for Earth's water found around remote baby star

Astronomers studying a remote baby star have found a missing link that could finally explain the origins of water on Earth, a new study suggests. By training a powerful radio telescope at V883 Orionis, a protostar 1,300 light-years away from Earth in the constellation Orion, astronomers have spotted gaseous water...

In a 1st, scientists predicted that volcanic comet was due to pop 'like a Champagne bottle' — and it did

Astronomers recently rejoiced after witnessing a bizarre volcanic comet erupt like a Champagne bottle, spraying gas and ice through the solar system like sparkling wine. The unusual explosion was a cause for celebration because, for the first time, the researchers successfully predicted it was going to happen. The volatile comet,...

City-size comet headed toward Earth 'grows horns' after massive volcanic eruption

An unusual volcanic comet flying toward the sun appears to have grown horns after it exploded, causing it to shine like a small star and shower supercold magma into space. It is the first time this comet has been seen erupting in almost 70 years. The comet, named 12P/Pons-Brooks (12P),...

New 'potentially interstellar' comet will be visible to the naked eye next month before leaving our solar system forever

A newly discovered comet that's barreling toward Earth may have originated from outside our solar system — and will likely be catapulted back into interstellar space after performing an intense gravitational slingshot around the sun. Before it departs our cosmic neighborhood forever, the icy object will likely get 100 times...
