The 2015 edition of the 'Cassini Scientist for a Day' competition is now open to entries by students. The competition is designed to give the participants a taste of life as a space scientist. Students are invited to submit a 500-word essay explaining their choice of one of three targets to be imaged by the Cassini spacecraft in orbit around...

Observations by the NASA/ESA Hubble Space Telescope have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the Universe. Some of these galaxies formed just 600 million years after the Big Bang and are fainter than any other galaxy yet uncovered by Hubble.

Three mission assessment studies, of interest in the context of future calls for medium-size missions, are now available. The studies, into a cooled infrared telescope, a Jovian moon flyby mission, and an impactor on Europa, were carried out at ESA's Concurrent Design Facility (CDF) at the request of ESA's Future Missions Office.

Using images from the NASA/ESA Hubble Space Telescope and ESO's Very Large Telescope, astronomers have discovered never-before-seen structures within a dusty disc surrounding a nearby star. The fast-moving wave-like features in the disc of the star AU Microscopii are unlike anything ever observed, or even predicted, before now.

An international team of astronomers has discovered a gargantuan galaxy cluster with a core bursting with new stars — an incredibly rare find. The discovery, made with the help of the NASA/ESA Hubble Space Telescope, is the first to show that gigantic galaxies at the centres of massive clusters can grow significantly by feeding off gas stolen...
