An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbours to objects seen in the early years of the Universe. The 14-hour exposure shows objects around a billion times fainter than can be seen with the naked eye.
Sentinel-1A, Europe’s first satellite for Copernicus, is almost ready for launch on 3 April. Meanwhile, ESA is showing how its advanced radar will map ice, monitor subsidence and much more. Marking a new era in Earth observation focusing on operational applications, Sentinel-1A is set to deliver timely imagery for numerous Copernicus services.
With a mandate from the UN, ESA and other space agencies from around the world are about to establish a high-level group to help coordinate global response should a threatening asteroid ever be found heading towards Earth.
Ten years ago, on 14 January 2004, Mars Express took its very first images of Mars in color and in 3D.
Shortly after China’s Chang’e-3 spacecraft departed Earth to land on the Moon, ESA’s network of tracking stations swung into action, providing crucial support for the vessel’s five-day lunar cruise.
No matter how painstakingly we choose the materials to build satellites, once a mission is over they are just so much junk. But what if one day they could be recycled in space for future missions – perhaps as construction material, fuel or even food?
Since 2000, the four identical satellites of the Cluster quartet have been probing Earth’s magnetosphere in three dimensions. This week, two of them made their closest-ever approach, just 4 km, enabling valuable data to be acquired with unprecedented detail.
Craters once brim-full with sediments and water have long since drained dry, but traces of their former lives as muddy lakes cling on in the Martian desert.
ESA’s mission to Mars in 2016 has entered the final stage of construction with the signature of a contract this week with Thales Alenia Space at the Paris Air & Space Show.
Although nearly a thousand exoplanets have been detected indirectly — most using the radial velocity or transit methods — and many more candidates await confirmation, only a dozen exoplanets have been directly imaged.
The ESA (European Space Agency) has inaugurated a new hub that will strengthen Europe’s contribution to the global hunt for asteroids and other hazardous natural objects that may strike Earth.
A rare encounter between two gas-rich galaxies spotted by ESA’s (European Space Agency) Herschel space observatory indicates a solution to an outstanding problem: how did massive, passive galaxies form in the early Universe?
ESA (European Space Agency) astronaut Luca Parmitano left for Baikonur, Kazakhstan today, his last stop before heading to the International Space Station on 28 May.
The European Space Agency's (ESA) Herschel space observatory has made detailed observations of surprisingly hot molecular gas that may be orbiting or falling towards the supermassive black hole lurking at the center of our Milky Way galaxy.
Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, recently imaged by the European Space Agency's (ESA) Mars Express.
ESA’s Herschel space observatory has provided the first images of a dust belt – produced by colliding comets or asteroids – orbiting a subgiant star known to host a planetary system.
The European Space Agency's (ESA) Herschel observatory has captured a new view of a vast star-forming cloud called W3.
Astronomers have identified some of the youngest stars ever seen, thanks to the European Space Agency's (ESA) Herschel space observatory.
The European Space Agency (ESA) and the Russian federal space agency, Roscosmos, have signed a formal agreement to work in partnership on the ExoMars program towards the launch of two missions in 2016 and 2018.
ESA’s planning to crash a spacecraft into an asteroid called Didymos, to, well, see what happens.
