Hubble Confirms Largest Comet Nucleus Ever Seen

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 […]

Solar Orbiter catches a second comet by the tail

Solar Orbiter catches a second comet by the tail

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 […]

A Christmas comet for Solar Orbiter

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 […]

Monster comet falling toward the sun is bigger than a Martian moon

Monster comet falling toward the sun is bigger than a Martian moon

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.”

Interstellar comets like Borisov may not be all that rare

Interstellar comets like Borisov may not be all that rare

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.
