This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local Universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious...

This Announcement of Opportunity (AO) solicits proposals for the provision of the operations and scientific exploitation of the SPICE instrument on board the Solar Orbiter mission. The AO is open to scientists from the Member States of ESA. Letters of intent are due 20 July, 12:00 CEST (noon), and the deadline for proposals is 26 September,...

ESA's Venus Express may have helped to explain the puzzling lack of water on Venus. The planet has a surprisingly strong electric field – the first time this has been measured at any planet – that is sufficient to deplete its upper atmosphere of oxygen, one of the components of water.

During May 2016 the Earth and Mars get closer to each other than at any time in the last ten years. The NASA/ESA Hubble Space Telescope has exploited this special configuration to catch a new image of our red neighbour, showing some of its famous surface features. This image supplements previous Hubble observations of Mars and allows astronomers...

Saturn, its moons, and rings provide the inspiration behind the 'Cassini scientist for a day' competition that is designed to give school students a taste of life as a space scientist. More than 900 students from across Europe participated in the 2015–2016 competition and the winners have now been selected.

There is a wealth of evidence, collected over the past few decades, that suggests liquid water was abundant in the early history of Mars – one of our nearest and most studied neighbours. A recent study, using data from several spacecraft operating at Mars, paints a detailed picture of the rise and fall of standing bodies of water in a region of...

Through this Call for Missions the Director of Science solicits from the broad scientific community proposals for the competitive selection of mission concepts to be candidate for the implementation of a medium-size, or M-class, mission (M5). Proposals are due by 5 October 2016, 12:00 (noon) CEST. Proposals must be preceded by a Letter of Intent...

Saturn's largest moon is covered in seas and lakes of liquid hydrocarbons – and one sea has now been found to be filled with pure methane, with a seabed covered by a sludge of organic-rich material, and possibly surrounded by wetlands.
