Astronomers using the NASA/ESA Hubble Space Telescope have shown for the first time that bursts of star formation have a major impact far beyond the boundaries of their host galaxy.

The "PLATO 2.0 Science Workshop" will be held at ESA-ESTEC, Noordwijk, on 29-31 July, 2013. The workshop is open to the interested community and will examine the impact that PLATO will make on all areas of exoplanet, stellar, and legacy science areas.

To celebrate its 23rd year in orbit, the NASA/ESA Hubble Space Telescope has released a stunning new image of one of the most distinctive objects in our skies: the Horsehead Nebula.

ESA's Herschel space observatory has discovered an extremely distant galaxy making stars more than 2000 times faster than our own Milky Way. Seen at a time when the Universe was less than a billion years old, its mere existence challenges our theories of galaxy evolution.

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 NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances. This supernova exploded more than 10 billion years ago (redshift 1.914), at a time the Universe was in its early formative years and stars were being born at a rapid rate.

Cosmologists have used data from Planck to reveal the distribution of dark matter across 13 billion years of cosmic history, as seen projected on the sky. This image was created by analysing the gravitational lensing effect imprinted by cosmic structure on the Cosmic Microwave Background.

Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy.

The NASA/ESA Hubble Space Telescope has captured this vivid image of spiral galaxy Messier 77, one of the most famous and well-studied galaxies in the sky.

In this new view of a vast star-forming cloud called W3, ESA's Herschel space observatory tells the story of how massive stars are born.

Planck's first all-sky image of the Cosmic Microwave Background is the most precise picture of the early Universe so far. Whilst the data agree well with the standard model of cosmology, the great quality of this image highlights significant anomalies challenging the foundations of our current understanding of the Universe.

The Director of Science and Robotic Exploration has released an Announcement of Opportunity (AO) for membership in the science team of the Gaia mission. The AO is open to all scientists from institutions located in ESA Member States. The deadline for receipt of proposals is 30 April 2013.

ESA's XMM-Newton space telescope has helped to identify a star and a black hole that orbit each other at the dizzying rate of once every 2.4 hours, smashing the previous record by nearly an hour.

For the first time, astronomers have detected far-infrared emission from jets in a black-hole binary system. Since this emission arises from the base of the jets, the observations are a crucial addition to the understanding of black-hole jets.

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.

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.

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.

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.
