This Call, open to the broad scientific community, solicits White Papers to propose science themes and associated questions to be addressed by ESA's next two large (L-class) missions, L2 and L3. The submission deadline for White Papers is 24 May 2013, 12:00 CEST (noon).

The NASA/ESA Hubble Space Telescope is one of the most powerful available to astronomers, but sometimes it too needs a helping hand. This comes in the form of Einstein's general theory of relativity, which makes galaxy clusters act as natural lenses, amplifying the light coming from very distant galaxies.

ESA's Herschel space observatory is expected to exhaust its supply of liquid helium coolant in the coming weeks after spending more than three exciting years studying the cool Universe.

Students from across Europe have been selected as winners of the Cassini Scientist for a Day 2012 competition. Coordinated by ESA, national competitions were held in several European countries, with more than 1000 entries. An equivalent competition was run by NASA for schools in the US.

A new study of X-ray emitting binary systems of massive stars, using data from ESA's INTEGRAL space observatory, has made it possible to reconstruct the locations of the Milky Way's spiral arms many millions of years ago.

A rapidly rotating supermassive black hole has been found in the heart of a spiral galaxy by ESA's XMM-Newton and NASA's NuSTAR space observatories, opening a new window into how galaxies grow.

The Director of Science and Robotic Exploration will soon release a Call for White Papers, soliciting proposals for the science themes to be addressed by the two next Large (L-class) missions in ESA's Cosmic Vision plan (L2 and L3).

The JUpiter ICy moons Explorer mission, JUICE, will carry a total of 11 scientific experiments to study the gas giant planet and its large ocean-bearing moons, ESA announced today.

ESA's Herschel space observatory has detected a cool layer in the atmosphere of Alpha Centauri A, the first time this has been seen in a star beyond our own Sun.

During an unusually strong blast of solar wind arriving at Saturn, the Cassini spacecraft detected particle acceleration to ultra-high energies, similar to what takes place around supernova explosions.

The possible effects of supermassive black holes on star formation in their host galaxies pose a tricky puzzle. Galaxy surveys from Herschel are being used to try to understand this complex interaction.

The Hubble Space Telescope has produced a time-lapse movie of a mysterious protostar that behaves like a flashing light.

The NASA/ESA Hubble Space Telescope - with a little help from an amateur astronomer - has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbour by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own.

ESA's XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it is not a uniform breeze but is fragmented into hundreds of thousands of pieces.

Astronomers using Herschel have found heavy molecular hydrogen in the protoplanetary disc around nearby star TW Hydrae. The observations enabled an estimate of the gaseous disc's mass, which is equivalent to 50 Jupiters.

Measurements obtained with ESA's Venus Express spacecraft have shed new light on the interaction between the solar wind and the second planet from the Sun.

Monitoring a pulsar with XMM-Newton, astronomers discovered X-ray variations that mimic in reverse similar changes seen in radio waves. This switching behaviour, which occurs within only a few seconds, challenges the current understanding of pulsars.

NASA has officially joined ESA's Euclid mission, a space telescope designed to investigate the mysterious natures of dark matter and dark energy.

Nearly 200 000 light-years from Earth, in the Large Magellanic Cloud, newly formed stars light up gas clouds in a riot of colours, visible in this image from the Hubble Space Telescope.

ESA's Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective.
