As Rosetta made its final approach to Comet 67P/Churyumov-Gerasimenko, we asked you to join this extraordinary adventure by sharing pictures of your journeys, participating in a fun photo contest that attracted hundreds of entries and nearly 23 000 votes.
Astronomers using ESA’s INTEGRAL gamma-ray observatory have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae. The finding came after the unique signature of gamma rays from the radioactive elements created in one of these explosions was captured for the first time.
Although it was only launched a few months ago and is still being commissioned, the new Sentinel-1A radar satellite has already shown that it can be used to generate 3D models of Earth’s surface and will be able to closely monitor land and ice surface deformation.
Using detailed information collected by ESA’s Rosetta spacecraft during its first two weeks at Comet 67P/Churyumov-Gerasimenko, five locations have been identified as candidate sites to set down the Philae lander in November – the first time a landing on a comet has ever been attempted.
Following the announcement made by Arianespace on the anomalies of the orbit injection of the Galileo satellites, the teams of industries and agencies involved in the early operations of the satellites are investigating the potential implications on the mission.
The next pair of Galileo satellites, Galileo 5 and 6, has been successfully delivered into orbit today. This launch marks the start of a new phase in the European satellite navigation programme where the full constellation will be deployed with short intervals between launches.
