NGC 7252 Galaxy (Atoms-for-peace) in Aquarius

This peculiar galaxy (typed SB0) of apparent magnitude 11.2mag and sized  1,9′ × 1,6′ can be found in the consrellation of Aquarius.With a real distance of 220 Mio.light-years two galaxies are heavily merging,giving them the look of an atom,circeled by some electrons.(Peace-Speech of President Eisenhower in 1953).It was first seen by William Herschel in 1785.

The special shape of NGC7252 results from the merging of two galaxies.Strong X-ray emissions have their origin in wether nuclear activiy or an intermediate black hole.The central structure is pinwheel shaped (HST picture,look here) and can not be detected on earthbased photographs.
