After nearly two years apart, Europe's Rosetta spacecraft will join stranded robot probe Philae on September 30 on the icy surface of a comet hurtling through space, their eternal resting place, mission control said Thursday.
Europe's trailblazing spacecraft Rosetta has resumed its exploration of a comet hurtling through the Solar System after a "dramatic weekend" in which contact with Earth was lost for nearly 24 hours, mission control said Thursday.
Astronomers using NASA's Hubble Space Telescope captured images of Comet 252P/LINEAR just after a close encounter with Earth on March 21. The close proximity to the comet offered scientists new insights on the body's nucleus.
For millennia, people on Earth have watched comets in the sky. Many ancient cultures saw comets as the harbingers of doom, but today scientists know that comets are really frozen balls of dust, gas, and rock and may have ...
Philae, the little lander that was declared lost by the European Space Agency (ESA), has achieved a lot despite its relatively short operational life on the surface of the comet 67P/Churyumov-Gerasimenko. Future comet landing ...
Rosetta's comet has been seen changing colour and brightness in front of the ESA orbiter's eyes, as the Sun's heat strips away the older surface to reveal fresher material.
Astronomers were watching when comet P/2016 BA14 flew past Earth on March 22. At the time of its closest approach, the comet was about 2.2 million miles (3.5 million kilometers) away, making it the third closest comet flyby ...
Two comets that will safely fly past Earth later this month may have more in common than their intriguingly similar orbits. They may be twins of a sort.
Scientists gave up Friday trying to contact robot lab Philae, stubbornly silent on the surface of a comet streaking through space—closing a captivating chapter in an historic quest.
There are no large caverns inside Comet 67P/Churyumov-Gerasimenko. ESA's Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery.
