Hubble digs glowing galactic worm


Picture of a charming dazzling galaxy, recognized as IRAS 23436 5257, it was Space Telescope, NASA / European Space Agency "Hubble." This galaxy is located in the northern constellation Cassiopeia, which was named in honor of the arrogant, conceited, but, nevertheless, a beautiful mythical queen.


Distort, like a worm structure of this galaxy, most likely, is the result of the collision and subsequent merger of two galaxies. These interactions are fairly common in the universe, and they may include how to capture a small satellite galaxy spiral arms of other galaxies and large collision between two galaxies. Friction between the particles of gas and dust can have a significant influence on the parties in the clash of the galaxy, changing their shape and cutting of these fancy new structures.

Persistence, remaining after such intergalactic collisions helps scientists understand the dynamics of these events, which can be of great value in the study of the behavior of our joint Milky Way galaxy, which is on a collision course with the nearby galaxy Messier 31.
