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.
A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilization, research suggests.
Unusual Comet – 1000 Times More Massive Than Typical – Discovered in Outer Solar System by Dark Energy Survey
Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times.
The boozy Christmas Comet! Bright green iceball that once came within 7.1 million miles of Earth is found to contain ‘abnormally high’ levels of ALCOHOL
46P/Wirtanen, also known as the Christmas Comet, was first seen in the 1940s
