After a 10-years-long journey ESA’s Rosetta has today caught comet 67P/Churyumov-Gerasimenko. Rosetta is now the first spacecraft to rendezvous a comet. “We are delighted to announce finally ‘we are here’,” said Jean-Jacques Dordain, ESA’s Director General, after Rosetta completed its manoeuvres.

A new research demonstrated that more than four billion years ago a massive asteroid moulded Earth’s surface. NASA’s Solar System Exploration Research Virtual Institute (SSERVI) and several international researchers analysed the role played by the asteroid in the transformation of our Planet surface. The

New results of comet ISON’s “final” hours

Jul 24

Last year Comet ISON, famous as “the Comet of the century”, died. The new analysis of data collected by ESA/NASA Solar and Heliospheric Observatory (SOHO) showed that comet ISON ceased producing dust and gas before its flyby of the Sun.

Comet ISON was discovered in 2012 and, thanks to its first trip aroundthe Sun and its brightness, was called “Comet of the century”. Unfortunately, astronomers’ hopes crumbled when they

Rosetta spacecraft and comet 67P/Churyumov-Gerasimenko: a comparison of their size

Jul 16

ESA released a short video where Rosetta spacecraft and comet 67P/Churyumov-Gerasimenko size is compared. The animation shows that Rosetta spacecraft is 32-metres-large while the comet measures 4000 meters, so 125 times Rosetta’s width.

Thanks to this animation it is possible to get the huge difference between the spacecraft and the comet.

In the first part of August Rosetta will reach the
