NASA’s Hubble Space Telescope has determined the size of the largest icy comet nucleus ever seen by astronomers. The estimated diameter is approximately 80 miles across, making it larger than the state of Rhode Island. The nucleus is about 50 times larger than found at the heart of most known comets. Its mass is estimated […]

Adapted from ESA Science and Exploration Page For the second time in its mission, the ESA/NASA Solar Orbiter spacecraft has flown through the tail of a comet. Predicted in advance by astronomers at University College London, UK, the spacecraft collected a wealth of scientific data that now awaits full analysis. For a spacecraft designed to […]
This post was repurposed from the ESA Science and Exploration page. Comet Leonard, a mass of space dust, rock and ice about a kilometre across is heading for a close pass of the Sun on 3 January, and the ESA/NASA Solar Orbiter spacecraft has been watching its evolution over the last days. The Solar Orbiter Heliospheric Imager […]
The wonky-shaped Comet 67P made its closest approach to Earth on Friday (Nov. 12).
Heat from a comet exploding just above the ground fused the sandy soil into patches of glass stretching 75 kilometers, a study led by Brown University researchers found
Earlier this year, two astronomers discovered what could be the largest comet ever seen in the solar system while combing through data collected by the Dark Energy Survey. Now, a new study led by the same scientists describes this beefy deep space monster as the “nearly spherical cow of comets.”
In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the icy snowball traveled 110,000 miles per hour and marked the first and only interstellar comet ever detected by humans.
Comet Bernardinelli-Bernstein will make its closest approach to our sun in 2031, but you’ll likely need a large amateur telescope to see it.
Megacomet that is 1,000 TIMES larger than a normal comet has first signs of activity with gas and dust spreading all over its massive core
Astronomers in New Zealand have spotted the first activity on the megacomet C/2014 UN271, perhaps the most massive comet discovered in recorded history.
