In the search for rogue planets and failed stars, astronomers using the NASA/ESA Hubble Space Telescope have created a new mosaic image of the #Orion nebula. During their survey of the famous star formation region, they found what may be the missing piece of a cosmic puzzle: the third, long-lost member of a star system that had broken apart...

Head of ESA's European Astronaut Centre, Frank De Winne, astronaut Matthias Maurer and Spaceship EAC head Aidan Cowley talk about exoplanets and how ESA prepares to go back to the Moon, Mars and beyond in this last instalment from Mass Effect's ESA Science series...
World Water Day reminds us of the need to treat and reuse wastewater. Satellites like Sentinel-2 provide key information on water quality. In this Sentinel-2 image, we can see black plumes of water pollution seeping into the Laguna de Bay in the Philippines.
Strong electric currents in the upper atmosphere are known to vary according to the season, but the Swarm satellite mission has discovered that this seasonal variation is not the same in the north and south polar regions.
Quoi de spécial sur cette photo ? On y voit un volcan en éruption et la lave en fusion est visible depuis l’espace, de nuit !! Ce sont les coulées rouges, à gauche de la photo. L’Etna, en Sicile, est actif depuis quelques temps. J’avais posté une photo de jour il y a peu. [ Flic.kr Link ]
Growing fractures, collapsing cliffs, rolling boulders and moving material burying some features on the comet’s surface while exhuming others are among the remarkable changes documented during the Rosetta Mission.
While the world marks the International Day of Forests, satellites continue to monitor the long-term effects of human activities on our planet’s precious resources. By comparing a Landsat-5 image from 1985 with a Sentinel-2 image from 2016, we can see where vegetation has been cleared away for logging, farming and other activities.
The international Cassini spacecraft zoomed in on Saturn's A ring, revealing narrow, detailed structures. High-resolution images like this help scientists to map the fine structure of Saturn's rings. But even this level of detail is not enough to resolve the individual particles that make up the ring. Features around a kilometre in size are resolvable, but here particles typically range in...

On Monday next week, the 4th ExoMars Landing Site Selection Workshop will take place at #ESTEC, the Netherlands, which will make its recommendation for which two landing sites should continue to be studied for the #ExoMars 2020 mission.
Some galaxies are harder to classify than others. Here, the NASA/ESA Hubble Space Telescope captured a striking view of two interacting galaxies NGC 3447 (or sometimes NGC 3447B and the smaller clump to the upper left, NGC 3447A). The problem is, we don't know what they might have looked like before they started interacting... See [ Spacetelescope.org Link ]
Apparently it's #InternationalDayOfHappiness... OK, so we'll go with this - sharing pics like this with you makes us happy! ;-)
