NASA's Goddard Space Flight Center 21 Sep 2018, 17:00 UTC Today, NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars.
ESA Space Science 21 Sep 2018, 15:22 UTC An odd-shaped formation of gas and dust at the centre of the Milky Way, captured by the far-infrared cameras on board ESA’s Herschel space observatory. The nearly continuous strip of dense and cold clumps of material forms an infinity symbol, or sideways 8, that is a few hundred light years across. In this image, the strip twists around an invisible axis running roughly from the top left to the bottom right.
NASA's Goddard Space Flight Center 21 Sep 2018, 13:38 UTC In the northern constellation of Coma Berenices (Berenice's Hair) lies the impressive Coma Cluster — a structure of over a thousand galaxies bound together by gravity. Many of these galaxies are elliptical types, as is the brighter of the two galaxies dominating this image: NGC 4860 (center). However, the outskirts of the cluster also host younger spiral galaxies that proudly display their swirling arms. Again, this image shows a wonderful example of such a galaxy in the shape of the beautiful NGC 4858, which can be seen to the left of its bright neighbor and which stands out on account of its unusual, tangled, fiery appearance.
Europlanet Research Infrastructure 20 Sep 2018, 10:02 UTC The discovery of a microorganism that gives a candy-pink lagoon in central Spain its startling colour is providing new evidence for how life could survive on a high-salt diet on Mars or Europa.
ESA Top News 20 Sep 2018, 09:00 UTC These prominent trenches were formed by faults that pulled the planet’s surface apart less than 10 million years ago.
NASA Lunar Science Institute 19 Sep 2018, 19:54 UTC The moon is often thought of as a lifeless and inactive place. But a new study reminds us that our pale celestial guardian is more dynamic than it seems from afar. Fresh measurements of its flimsy atmosphere back up the idea that our lunar companion is surrounded by an electric shell, and that shell seems to gather power when Earth shields it from the fury of the sun during a full moon.
ESA Top News 19 Sep 2018, 07:00 UTC Astronauts on a mission to Mars would be exposed to at least 60% of the total radiation dose limit recommended for their career during the journey itself to and from the Red Planet, according to data from the ESA-Roscosmos ExoMars Trace Gas Orbiter being presented at the European Planetary Science Congress, EPSC, in Berlin, Germany, this week.
