(Credit: Simone Marchi/SwRI) 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 results of the study were published yesterday on the science journal “Nature”. According to Yvonne
New results of comet ISON’s “final” hours
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 observed that ISON became soon clear.
Rosetta spacecraft and comet 67P/Churyumov-Gerasimenko: a comparison of their size
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. (Video: ESA) 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 comet at an altitude of 100 km. Then, during September and October
The NEOShield Project at the SpaceUp UK
The NEOShield Team participated in the SpaceUp UK “unconference” in London on 5-6 July. (Image: SpaceUp UK/Alex Neumann) The SpaceUp “unconference” is a special event that permits to experts and enthusiasts to talk about space in a comfortable atmosphere which makes this experience unique. (Image: SpaceUpUK) The unconference, the first ever organized in the UK, gathered people from different countries and with different backgrounds that, thanks to activities like the T-5 talk, had the opportunity
