(Phys.org) —A new analysis of data from the ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft has revealed that comet 2012/S1 (ISON) stopped producing dust and gas shortly before it raced past the Sun and disintegrated.
ESA's Rosetta spacecraft has found the water vapour from its target comet to be significantly different to that found on Earth. The discovery fuels the debate on the origin of our planet's oceans.
No, scientists haven't found Philae yet. But as they churn through the scientific data on the comet lander, more information is emerging about the crazy landing last month that included three touchdowns and an incredible ...
Scientists working with data sent back by the now-slumbering Philae lander have announced the discovery of organic molecules on the comet 67P/Churyumov-Gerasimenko.
The nucleus of comet 67P/Churyumov-Gerasimenko is an irregularly shaped body as seen from ESA's spacecraft Rosetta. New images of the comet obtained by OSIRIS, the onboard scientific imaging system, reveal a unique shape. ...
Europe's deep-space robot lab Philae worked against the clock Friday, attempting to drill into a comet 510 million kilometres (320 million miles) from Earth to crown a historic exploration before its battery runs out.
A space probe aiming to become the first to land on a comet has taken images that appear to show its target could actually be two separate lumps of rock and ice, scientists said Thursday.
The drama of Philae's slow fall, bounce and unfortunate slide into hibernation was one of the most thrilling science stories of a generation. But what in its short 60 hours of life on Comet 67P did it achieve?
(Phys.org) —NASA's NEOWISE mission captured a series of pictures of comet C/2012 K1—also known as comet Pan-STARRS—as it swept across our skies in May 2014.
Comet C/2013 UQ4 (Catalina) has been observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet glows brightly ...
