Arp 87 and the two spiral galaxies NGC 3808 and NGC 3808A, are in an early state of merging. Already a bridge between them has formed. A polar ring around NGC 3808A attests to a former fusion of galaxies. Constellation: Leo. Distance: 300 million light-years. Visual magnitude: 14.1. Type: Sc D.
Edited ESO image of the spiral galaxy NGC 1097. Original caption: It is an almost-true colour composite based on images made with the multi-mode VIMOS instrument on the 8.2-m Melipal (Unit Telescope 3) of ESO's Very Large Telescope. Exposures were taken in three different wavebands which were associated to a given colour : R-band (centred around 652 nm; red), V (540 nm; green) and B (456 nm; blue). The images were taken on the night of December 9 to 10, 2004 in the presence of the President…

El Hubble captura dos galaxias a punto de chocar entre ellas. El telescopio Hubble ha captado una imagen de dos galaxias cercanas muy próximas a colisionar. Se trata del sistema Arp 256 compuesto por dos galaxias espirales, ambas a mas de 350 millones años luz de nuestro planeta.
