Scientists have confirmed the presence of PAHs - Polycyclic Aromatic Hydrocarbons - in the upper atmosphere of Saturn's largest moon, Titan. After forming, PAHs grow into larger aggregates that drift down, eventually giving rise to aerosol particles in the haze layer that blankets Titan's surface. The study is based on data from the Cassini...

New global maps of Mars released on the 10th anniversary of the launch of ESA's Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.

The NASA/ESA Hubble Space Telescope has produced the most detailed observations ever of the Ring Nebula (Messier 57). This image reveals intricate structure only hinted at in previous observations, and has allowed scientists to construct a model of the nebula in 3D - showing the true shape of this striking object.

Astronomers have found a rare encounter between two massive and gas-rich galaxies in a survey from Herschel. The event took place when the Universe was only about three billion years old and involved two galaxies forming stars with exceptional efficiency whilst in the process of merging. This galactic collision would go on to form a very massive...

The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say...

Observing the Galactic Centre with Herschel, astronomers have detected molecular gas at surprisingly high temperatures - up to 1000 K. The molecules are probably heated up by shocks as gas surges towards Sagittarius A*, the region harbouring the supermassive black hole at the centre of the Milky Way.

For the first time, scientists have resolved the detailed structure of the core region where magnetic reconnection takes place in the magnetosphere of Earth using unprecedented wave measurements. The study, based on data from ESA's Cluster mission, has mapped different types of electrostatic waves in this region. The waves trace populations of...

The Netherlands, Poland, and Romania have all become Participating States in PRODEX. The declarations were signed on 21 November, 2012, following the ESA Council at Ministerial Level, opening the door for all three countries to become involved in projects through the PRODEX office.

The Herschel space observatory has exhausted its supply of liquid helium, after more than three years of observations and revelations about how galaxies, stars, and planets form and evolve. Ground-breaking discoveries are in store for years to come.

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.

Herschel has yielded proof that almost all the water in Jupiter's stratosphere was delivered by comet Shoemaker-Levy 9, which impacted the planet in 1994. The new Herschel map shows more water in Jupiter's southern hemisphere, where the impacts occurred, than in the north.

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.

A new study has revealed that bursty bulk flows - fast streams of plasma launched towards Earth during magnetic substorms - are more important than previously thought and can carry one third of the total energy that brightens aurorae.

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.
