OBJECT DESCRIPTION AND IMAGE SESSION

NGC 6872, is a large barred spiral galaxy with a peculiar shape that resemble a big bird with open wings, thus it has the nickname of the "Condor Galaxy". NGC 6872 is interacting with the lenticular galaxy IC 4970 which is less than one tenth of the size of NGC 4872. The galaxy has two elongated arms measuring a stellar diameter over 700.000 light years across making one of the largest spiral galaxy known. The galaxy was discovered by English astronomer John Herschel in June 1835 from South Africa.

On the upper right we have NGC 6876 an elliptical galaxy which is moving away from NGC 6872. There are many distant galaxies in the background that are labelled in the annotated image below.
