How to Find Rosetta’s Comet In Your Telescope

How would you like to see one of the most famous comets with your own eyes? Comet 67P/Churyumov-Gerasimenko plies the morning sky, a little blot of fuzzy light toting an amazing visitor along for the ride — the Rosetta spacecraft. When you look at the coma and realize a human-made machine is buzzing around inside, it […]

More Evidence That Comets May Have Brought Life to Earth

The idea of panspermia — that life on Earth originated from comets or asteroids bombarding our planet — is not new. But new research may have given the theory a boost. Scientists from Japan say their experiments show that early comet impacts could have caused amino acids to change into peptides, becoming the first building […]

Spectacular Celestial Fireworks Commemorate Perihelion Passage of Rosetta’s Comet

A spectacular display of celestial fireworks like none ever witnessed before, burst forth from Rosetta’s comet right on time – commemorating the Europeans spacecraft’s history making perihelion passage after a year long wait of mounting excitement and breathtaking science. As ESA’s Rosetta marked its closest approach to the Sun (perihelion) at exactly 02:03 GMT on […]

Dramatic Outburst at Rosetta’s Comet Just Days Before Perihelion

A comet on a comet? That’s what it looks like, but you’re witnessing the most dramatic outburst ever recorded at 67P/Churyumov-Gerasimenko by the Rosetta spacecraft. The brilliant plume of gas and dust erupted on July 29 just two weeks before perihelion. In a remarkable display of how quickly conditions on a comet can change, the outburst lasted only about 18 minutes, […]

Rosetta’s Comet Sparkles with Ice, Blows Dust From Sinkholes

Comet 67P/C-G may be tiny at just 2.5 miles (4 km) across, but its diverse landscapes and the processes that shape them astound. To say nature packs a lot into small packages is an understatement. In newly-released images taken by Rosetta’s high-resolution OSIRIS science camera, the comet almost seems alive. Sunlight glints off icy boulders and pancaking sinkholes […]

Philae Wakes Up, Makes Contact!

Fantastic news! Philae’s alive and kicking. The lander “spoke” with its team on ground via Rosetta for 85 seconds — its first contact since going into hibernation in November. Signals were received at ESA’s European Space Operations Centre in Darmstadt at 4:28 p.m. EDT yesterday June 13. The lander sent more than 300 data packets reporting on its condition […]

Have We Found Rosetta’s Lost Philae Lander?

It’s only a bright dot in a landscape of crenulated rocks, but the Rosetta team thinks it might be Philae, the little comet lander lost since November. (…)Read the rest of Have We Found Rosetta’s Lost Philae Lander?

Rosetta’s Comet Keeps On Jetting Even After the Sun Goes Down

67P/Churyumov-Gerasimenko certainly isn’t a comet that dreads sundown. Images acquired by the OSIRIS instrument aboard ESA’s Rosetta spacecraft in April 2015 reveal that some of the comet’s dust jets keep on firing even after the Sun has “set” across those regions. This shows that, as the comet continues to approach its August perihelion date, it’s now […]

Rosetta Discovery of Surprise Molecular Breakup Mechanism in Comet Coma Alters Perceptions

A NASA science instrument flying aboard the European Space Agency’s (ESA) Rosetta spacecraft has made a very surprising discovery – namely that the molecular breakup mechanism of “water and carbon dioxide molecules spewing from the comet’s surface” into the atmosphere of comet 67P/Churyumov-Gerasimenko is caused by “electrons close to the surface.” The surprising results relating […]
