USA: Devils Eyes reveals its secrets




The collision of two star systems has led to the creation of a new galaxy with an unusual appearance and strange movements. At the galaxy M64 in front of her bright nucleus is a dark band of dust that gave reason to call it the "Black Eye" or "Devil's eye." Observations using an orbital telescope "Hubble" showed that the gas in this galaxy moves in one direction towards the center, and then further in the opposite direction — outwardly. This unusual phenomenon — the result of a galactic collision.

M64 is well known to amateur astronomers to its characteristic form. It was first seen in the XVIII century French Messier, who included it in his famous catalog of celestial objects. At first glance, this is a perfectly normal spiral galaxy in the form of a pinwheel. As in most galaxies all star M64 rotating in the same direction. However, a recent detailed study showed that the interstellar gas in the outer regions of M64 rotates in the opposite direction than the gas and stars in the inner parts of the galaxy.

Astronomers believe that's hooked to the other side gas appeared when M64 absorbed a satellite galaxy that collided with it supposedly over a billion years ago. A picture taken with "Hubble" has shown that new stars are formed at the boundary where the oppositely directed streams of gas collide, are compressed and reduced. In the picture are especially noticeable hot young blue stars that formed recently — they are located next to the pink clouds of glowing hydrogen gas, glowing under the influence of ultraviolet radiation from young stars.

The smaller galaxy is absorbed by the big neighbor, almost completely destroyed: its star, or joined the main galaxy or were scattered on the endless intergalactic space.
