Located in the Fornax Galaxy Cluster some 60 million light-years from Earth, IC 335 is an edge-on lenticular system — an intermediate state in galaxy morphological classification schemes between true spiral and elliptical galaxies.
Tethys appears to be peeking out from behind Rhea in this image from the Cassini probe. Scientists believe that Tethys’ surprisingly high albedo is due to the water ice jets emerging from its neighbour, Enceladus.
This spectacular image of the brilliant young blue stars and contrasting red giants of open cluster Messier 47 in the southern constellation of Puppis was taken with the 2.2-metre MPG/ESO telescope at ESO’s La Silla Observatory in Chile.
NGC 2207 and IC 2163 are two colliding galaxies in the constellation of Ursa Major some 130 million light-years from Earth. Between them they have produced one of the most bountiful collections of ultraluminous X-ray sources (ULXs) known.
First or last Quarter Moon is the best time to see some of the magnificent crater chains near the centre of the Earth-turned lunar hemisphere. Marnix Praet from Belgium provides this high-resolution view of the Hipparchus and Albategnius region.
