This new NASA/ESA Hubble Space Telescope image shows ghostly green filaments, lying within galaxy UGC 11185.This filament was illuminated by a blast of radiation from a quasar - a very luminous and compact region that surrounds the supermassive black hole at the centre of its host galaxy.
This image shows the exoplanet WASP-12b - an alien world as black as fresh asphalt, orbiting a star like our Sun. Scientists were able to measure its albedo: the amount of light the planet reflects.
This NASA/ESA Hubble Space Telescope image shows a globular cluster known as NGC 104 - or, more commonly, 47 Tucanae, since it is part of the constellation of Tucana (The Toucan) in the southern sky.
Imaging of the Hubble Space Telescope's observations of Fomalhaut b's expanding dust cloud from 2004 to 2013. The cloud was produced in a collision between two large bodies orbiting the bright nearby star Fomalhaut. This is the first time such a catastrophic event around another star has been imaged.
