New Herschel images reveal the debris disc around the star Fomalhaut in its full glory. By probing the glow of dust in the disc, these data suggest that it consists of 'fluffy' aggregates of dust grains produced by cometary collisions.

Despite the absence of a large magnetosphere, the near-Venus environment exhibits a number of similarities with planets such as Earth. The latest, surprising, example is the evidence for magnetic reconnection in Venus' induced magnetotail.

Sub-millimetre observations of 2M1207, a brown dwarf with its own circumstellar disc and a planetary companion five times more massive than Jupiter, reopen the debate on how giant planets form around stellar and sub-stellar objects.

Astronomers have discovered that black-hole driven ultra-fast outflows are common in active galaxies, and they are massive and powerful enough to provide the feedback required by galactic evolution models.

Observations by the NASA/ESA Hubble Space Telescope have come up with a new class of planet, a waterworld enshrouded by a thick, steamy atmosphere. It's smaller than Uranus but larger than Earth.

Astronomers using the NASA/ESA Hubble Space Telescope have found a cluster of young blue stars surrounding a mid-sized black hole called HLX-1.

ESA's Venus Express spacecraft has discovered that our cloud-covered neighbour spins a little slower than previously measured. Peering through the dense atmosphere in the infrared, the orbiter found surface features were not quite where they should be.

The MARSIS radar instrument on board ESA's Mars Express orbiter has discovered a subsurface blanket of low density material around the north polar cap.

Astronomers have resolved, for the first time, the Vela pulsar wind nebula in the hard X-ray band and have exploited a special imaging technique to reveal a never-before-seen component of the source.

Using the Hubble Space Telescope, astronomers have uncovered a cluster of galaxies in the initial stages of development, making it the most distant such grouping ever observed in the early Universe.

Astronomers have used XMM-Newton and other telescopes to uncover an unusually slow X-ray pulsar still nestled in the remains of the supernova that created it.

A team of scientists has used the NASA/ESA Hubble Space Telescope to observe a quasar accretion disc - a brightly glowing disc of matter that is slowly being sucked into its galaxy's central black hole.

On 10 July 2010, ESA's Rosetta spacecraft flew past asteroid Lutetia, one of the largest objects orbiting within the main asteroid belt between Mars and Jupiter. Rosetta's encounter revealed an intriguing object which has survived since the birth of the planets.
