A team of British and American astronomers used data from several telescopes on the ground and in space - among them the NASA/ESA Hubble Space Telescope - to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth.
This image from the NASA/ESA Hubble Space Telescope reveals an ancient, glimmering ball of stars called NGC 1466. It is a globular cluster - a gathering of stars all held together by gravity - that is slowly moving through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbours.
HE0435-1223, located in the centre of this wide-field image, is among the five best lensed quasars discovered to date. The foreground galaxy creates four almost evenly distributed images of the distant quasar around it.
Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion
