Esa's Rosetta mission is currently making its way towards a comet in the solar system. And, in a series of stunning new images, it reveals how comet 67P/Churyumov-Gerasimenko has begun to develop into an exciting ball of dust and gas. Over a period of six weeks the comet has begun to extend its dusty veil known as a 'coma' into space.

Buffeted by the solar wind, Comet Lovejoy's crooked ion tail stretches over 3 degrees across this telescopic field of view, recorded on February 20. The starry background includes awesome bluish star Phi Persei below, and pretty planetary nebula M76 just above Lovejoy's long tail. Also known as the Little Dumbbell Nebula, after its brighter cousin M27 the Dumbbell Nebula, M76 is only a Full Moon's width away from the comet's greenish coma. Still shining in northern hemisphere skies, this Comet Lovejoy (C/2014 Q2) is outbound from the inner solar system some 10 light-minutes or 190 million kilometers from Earth. But the Little Dumbbell actually lies over 3 thousand light-years away. Now sweeping steadily north toward the constellation Cassiopeia Comet Lovejoy is fading more slowly than predicted and is still a good target for small telescopes.

Yesterday, when the Rosetta spacecraft was a mere 234 kilometers (145 miles) from the comet 67P/Churyumov-Gerasimenko (or just ChuGer) it took this amazing image with its navigational camera...

Mind you, the main OSIRIS camera has more resolution than the NAVCAM, so we'll be getting better pictures soon. And of course, Rosetta is still on the approach!

History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.

"We are the first to do this - and that [achievement] will stay forever." said Jean Jacques Dordain, Director General of ESA.



The comet, 67P/Churyumov–Gerasimenko, orbits, the sun every 6.45 years. It is 2.1 miles wide by 2.4 miles long.

Rosetta first launched in 2004 to research the comet, and it didn't arrived at its destination until this past August. On Wednesday morning, Philae first separated from the probe to attempt a landing.

Researchers are hoping to learn more about the origins of the solar system and whether or not comets could have brought water and life to Earth. Watch an ESA animated explanation of Rosetta's journey to the comet and it's surface mission below.

Comet Lovejoy, C/2014 Q2, is framed like a cosmic Christmas tree with starry decorations in this colorful telescopic portrait, snapped on December 16th. Its lovely coma is tinted green by diatomic C2 gas fluorescing in sunlight. Discovered in August of this year, this Comet Lovejoy is currently sweeping north through the constellation Columba, heading for Lepus south of Orion and bright enough to offer good binocular views. Not its first time through the inner Solar System, this Comet Lovejoy will pass closest to planet Earth on January 7,
