Retirement in the suburbs - Hubble traces the migration of white dwarfs in cluster 47 Tucanae [heic1510] 14 May 2015 Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, collected a census of young white dwarf stars beginning their migration from the crowded centre of an ancient star cluster to its less populated outskirts. The new results challenge our ideas about how and when a star loses its mass near the end of its life. Read more
The Hubble Space Telescope is a joint ESA/NASA project and was launched in 1990 by the Space Shuttle mission STS-31 into a low-Earth orbit 600 km above the ground. During its lifetime Hubble has become one of the most important science projects ever.
Celestial fireworks celebrate Hubble's 25th anniversary [heic1509] 23 April 2015 This vibrant image of the star cluster Westerlund 2 has been released to celebrate Hubble's 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science. Read more
Giant galaxies die from the inside out - Hubble and VLT observations show that star formation shuts down in the centres of elliptical galaxies first [heic1508] 16 April 2015 Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago.

Hubble finds ghosts of quasars past [heic1507] 02 April 2015 The NASA/ESA Hubble Space Telescope has imaged a set of enigmatic quasar ghosts - ethereal green objects which mark the graves of these objects that flickered to life and then faded. The eight unusual looped structures orbit their host galaxies and glow in a bright and eerie goblin-green hue. They offer new insights into the turbulent pasts of these galaxies. Read more
Dark matter even darker than once thought - Hubble explores the dark side of cosmic collisions [heic1506] 26 March 2015 Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results show that dark matter interacts with itself even less than previously thought. 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
