The European Space Agency (ESA) is an international organization with 18 member states headquartered in Paris, France with the purpose of combining talent, resources and funds to undertake space programs, study Earth, the Solar System and the Universe. The annual budget for ESA is over $3.5 billion. The primary member states are Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. In addition, Canada, Hungary, Romania operate under a cooperative agreement. Estonia and Slovenia have recently entered into a cooperative agreement.
Image: The lunar North Pole
The pockmarked landscape captured in this image from ESA's SMART-1 mission is the surface of our moon. Some of the many craters scattered across the lunar surface are clearly visible, records of the many impacts that have ...
Rosetta's first peek at the comet's south pole
Using the Microwave Instrument for the Rosetta Orbiter (MIRO), scientists have studied the comet's southern polar regions at the end of their long winter season. The data suggest that these dark, cold regions host ice within ...
ESA's Rosetta data reveals evidence for a daily water-ice cycle on and near the surface of comets
Comets are celestial bodies comprising a mixture of dust and ices, which they periodically shed as they swing towards their closest point to the Sun along their highly eccentric orbits.
SMOS meets ocean monsters
ESA's SMOS and two other satellites are together providing insight into how surface winds evolve under tropical storm clouds in the Pacific Ocean. This new information could to help predict extreme weather at sea.
When black holes collide
Picture the scene: two gigantic black holes, each one a good fraction of the size of our Solar System spiralling around each other. Closer and closer they draw until they touch and merge into a single, even more gigantic ...
Comet surface changes before Rosetta's eyes
In the months leading to the perihelion of Comet 67P/Churyumov-Gerasimenko, Rosetta scientists have been witnessing dramatic and rapid surface changes on the Imhotep region, as reported in a paper to be published in Astronomy ...
Space technology applied to stress testing for safer cars
A spacecraft tool is now improving car safety by stress-testing many of the internal computer systems to be sure they work well when the car is on the road.
Astronomers use cosmic gravity to create a 'black-hole-scope'
The Integral, Fermi and Swift space observatories have used the magnifying power of a cosmic lens to explore the inner regions of a supermassive black hole.
Exposed water ice detected on comet's surface
Using the high-resolution science camera on board ESA's Rosetta spacecraft, scientists have identified more than a hundred patches of water ice a few metres in size on the surface of Comet 67P/Churyumov-Gerasimenko.
Sweeping over the south pole of Mars
An unusual observation by Mars Express shows a sweeping view over the planet's south polar ice cap and across its ancient, cratered highlands.
