Hubble observes pitch black planet [heic1714] 14 September 2017 Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b's atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet. Read more

Hubble delivers first hints of possible water content of TRAPPIST-1 planets [heic1713] 31 August 2017 An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system, including the three planets within the habitable zone, might still harbour substantial amounts of water. Read more

Galactic David and Goliath [heic1712] 27 July 2017 The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Read more

The final frontier of the Frontier Fields [heic1711] 04 May 2017 The NASA/ESA Hubble Telescope has peered across six billion light years of space to resolve extremely faint features of the galaxy cluster Abell 370 that have not been seen before. Imaged here in stunning detail, Abell 370 is part of the Frontier Fields programme which uses massive galaxy clusters to study the mysteries of dark matter and the very early Universe. Read more

Hubble observes first multiple images of explosive distance indicator [heic1710] 20 April 2017 A Swedish-led team of astronomers used the NASA/ESA Hubble Space Telescope to analyse the multiple images of a gravitationally lensed type Ia supernova for the first time. The four images of the exploding star will be used to measure the expansion of the Universe. Read more

Media advisory: Hubble 25th anniversary events and image unveilings across Europe 01 April 2015 In January this year ESA/Hubble made a call for proposals to informal education venues across Europe to apply for a large-scale print of the Hubble 25th anniversary image. Read more
