    This movie shows the evolution of the stars in Leo IV, a dim dwarf galaxy in the halo of our Milky Way galaxy. The NASA/ESA Hubble Space Telescope measured the ages of these faint stars in Leo IV and two other similar galaxies, dubbed ultra-faint dwarf galaxies. The Hubble observations revealed that the stars in all three galaxies are more than 13 billion years old, almost as old as the 13.7-billion-year-old universe.

      This animation shows a galaxy undergoing a starburst. The galaxy has messy regions strung throughout its arms that are intensely bright and forming new stars. The winds produced by these star-forming processes can have an incredibly far-reaching effect on their host galaxy.

        This artist's illustration shows a star turning into a variable star, expanding and shrinking — growing brighter and dimmer as it does so. More information and download options: http://www.spacetelescope.org/videos/heic1323j/ Credit: NASA, ESA, M. Kornmesser

            This animation shows how the huge galaxy cluster MACS J1149+2223 — whose light took over 5 billion years to reach us — bends the light from a supernova lying behind the cluster so that Hubble captures four images of the supernova.

                This is an animation of a rare and exotic intermediate-mass black hole at the centre of a star cluster, similar to the one thought to be at the centre of globular cluster Messier 15. Studying these unusual black holes could tell us about how such objects grow and evolve within both star clusters and galaxies.

                  The music for this piece was completed on the twentieth anniversary of the first successful landing of a craft from Earth on the planet Mars on July 20, 1976. For many people, the Viking missions affirmed a sense that humankind was about to commence an extraordinarily significant period of historical development. The title of the work, Ares Vallis ("Mars Valley"), refers to an ancient floodplain on Mars that on July 4, 1997 became the landing site for the Mars Pathfinder spacecraft. Although the pace of exploration has turned out to be much slower than many of us had hoped, the dream remains. For further information, visit http://www.musicfromspace.com

                    This artist’s representation shows the gravitationally-lensed black hole PKS1830-211 and the sudden flaring seen with ALMA when material enters the base of the jet, close to the black hole itself. Orange indicates the jet seen in radio waves; green, blue, and red are the (changing) images seen with ALMA and the white flashes represent gamma rays.

                      This artist's impression shows how the effect of gravitational lensing by an intervening galaxy magnifies, brightens and distorts the appearance of a remote merging galaxy far behind it. The viewpoint of the observer moves sideways so that that the distant galaxy merger appears first to one side, where it is faint, and then appears right behind the foreground object and is dramatically magnified and its total apparent brightness increases.
