A cross-section of the universe

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.

Prepping for radar vision

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.

Getting ready for asteroids

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.

Video: The floodwaters of Mars

Ten years ago, on 14 January 2004, Mars Express took its very first images of Mars in color and in 3D.

Helping China to the moon

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.

What might recyclable satellites look like?

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?

ESA's Cluster Satellites in closest ever dance in space

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.

Water in a Martian desert

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 preps ExoMars mission for 2016

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.

ESA spots a light exoplanet

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.

ESA opens asteroid crisis center

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.

The secrets of galaxy evolution

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?

Next destination - space

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.

Hot molecular gas drawn to supermassive black hole at Milky Way center

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.

Underground explosions blamed for Martian craters

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.

Planets and debris litter this "retired" star

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.

In search of high-mass stars

The European Space Agency's (ESA) Herschel observatory has captured a new view of a vast star-forming cloud called W3.

Herschel space observatory spots some of the youngest stars ever seen

Astronomers have identified some of the youngest stars ever seen, thanks to the European Space Agency's (ESA) Herschel space observatory.

Russia and ESA clinch Mars exploration agreement

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 picks target asteroid for spaceship crash

ESA’s planning to crash a spacecraft into an asteroid called Didymos, to, well, see what happens.
