Recent observations have revealed carbon monoxide venting from the largest comet ever seen, providing clues about its origins ...

Astronomers have observed a giant comet hurtling towards the inner solar system, releasing superfast jets. It is spewing carbon monoxide from its surface at an absolutely insane speed. Comet C/2014 ...

Scientists aimed ALMA at the comet in March 2024 and saw carbon monoxide — a gas that usually doesn’t show up in observations that far away — gushing out of its surface in jets. The team also picked ...

As the comet approaches the sun, the comet's surface warms up, which releases gas along with ice-coated dust particles into the coma (the halo that develops around the nucleus).

Researchers are barely scratching the surface of these strange objects. A recent study suggested that nearly 60% of all near-Earth objects are dark comets that may have been a part of much larger ...

Scientists have gathered new evidence to suggest icy comets indeed brought water to Earth, long ago. Skip to main content. Open menu Close ... which can release gas and dust from the comet's surface.

Rosetta's mission, which ended with a controlled impact on the comet's surface on September 30, 2016, provided a treasure trove of data.

The devil comet is not a stranger. It’s been a friend to Earth for a while. This comet, also known as 12P/Pons-Brooks, orbits the sun once a little over every 71 years. This comet was discovered ...

By building a 3D image of part of the surface of a comet called 67P, astronomers have discovered caves up to 47 metres deep. By Alex Wilkins. 12 January 2024 ...

A comet the size of a city has regained its appearance of having a pair of horns following a volcanic eruption that occurred on the comet's surface. The comet, 12P/Pons-Brooks, experienced its ...

Comets’ orbits can be very long, meaning they may spend most of their time in far-off reaches of the solar system. An object will orbit faster the closer it is to the Sun, as angular momentum is ...
