This spectacular picture from the NASA/ESA Hubble Area Telescope reveals the trailing arms of NGC 2276, a spiral galaxy 120 million light-years away within the constellation of Cepheus. At first look, the fragile tracery of brilliant spiral arms and darkish mud lanes resembles numerous different spiral galaxies. A better look reveals a surprisingly lopsided galaxy formed by gravitational interplay and intense star formation.
This placing picture showcases the unusually contorted look of NGC 2276, an look attributable to two completely different astrophysical interactions — one with the superheated fuel pervading galaxy clusters, and one with a close-by galactic neighbor.
The interplay of NGC 2276 with the intracluster medium — the superheated fuel mendacity between the galaxies in galaxy clusters — has ignited a burst of star formation alongside one fringe of the galaxy. This wave of star formation is seen as the intense, blue-tinged glow of newly fashioned huge stars in the direction of the left facet of this picture, and provides the galaxy a surprisingly lopsided look. NGC 2276’s current burst of star formation can also be associated to the looks of extra unique inhabitants — black holes and neutron stars in binary methods.
On the opposite facet of the galaxy from this burst of latest stars, the gravitational attraction of a smaller companion is pulling the outer edges of NGC 2276 off form. This interplay with the small lens-shaped galaxy NGC 2300 has distorted the outermost spiral arms of NGC 2276, giving the misunderstanding that the bigger galaxy is oriented face-on to Earth. NGC 2276 and its disruptive companion NGC 2300 can each be seen within the accompanying picture, which reveals a wider view of the interacting galaxies.
NGC 2276 is on no account the one galaxy with an odd look. The Atlas of Peculiar Galaxies — a catalog of surprising galaxies printed in 1966 — incorporates a menagerie of bizarre galaxies, together with spectacular galaxy mergers, ring-shaped galaxies, and different galactic oddities. As befits an unusually contorted galaxy, NGC 2276 has the excellence of being listed within the Atlas of Peculiar Galaxies twice — as soon as for its lopsided spiral arms and as soon as for its interplay with its smaller neighbor NGC 2300.
- The precise alignment of NGC 2276 may be inferred from the place of its brightly glowing galactic core, which is offset from the distorted spiral arms.
