The deep, dark twilight zone a kilometre down in the ocean is home to most of the world's fish, but how they get enough food has largely been a mystery. Now, thanks to satellites and floating sensors, scientists have worked out how much energy is being pumped to the depths.

An app that uses satellite data to evaluate the quality of wine took home the top prize at this year's Space App Camp at ESA's centre in Frascati, Italy.

On 24 August, an earthquake struck central Italy, claiming at least 290 lives and causing widespread damage. Satellite images are being used to help emergency aid organisations, while scientists have begun to analyse ground movement.

Wildlife habitats close to airports pose a serious risk to safety at takeoff and landing. Thanks to ESA, a new service lets airports use satellites to identify and manage these areas.

If a plant isn't green it doesn't mean it can't photosynthesise as well as its more usual counterpart, but when measured by satellites, these non-green varieties skew results on plant health. FLEX is different. Experiments using 'mutants' show that colour won't be an obstacle in this new mission's task of mapping plant health from space.

ESA's SMOS satellite has found a rise in fresh water in the tropical Pacific Ocean during last year's El Niño event.
