NGC 6872 and IC 4970

interacting galaxies,colliding galaxies

This image is a three-colour composite, this time reproduced from one blue (B), one green-yellow (V) and one red (R) exposure, obtained with FORS1 at ANTU in the morning of March 29, 1999. The field size is again 6.8×6.8 arcmin 2. It shows the spectacular barred spiral galaxy NGC 6872 that is shaped like an “integral sign”. It is of type SBb and is accompanied by a smaller, interacting galaxy, IC 4970 of type S0 (just above the centre). The bright object to the lower right of the galaxies is a star in the Milky Way whose image has been strongly overexposed and exhibits multiple optical reflections in the telescope and instrument.
