Photo of the day | irregular galaxy ESO 149-3





Usually galaxies are divided into two main categories – spiral and elliptical. In the first category, for example, relates our galaxy the Milky Way and most other galaxies in the universe. The second category is usually referred biggest space education. When our galaxy collide with the Andromeda galaxy, about two billion years, the two spiral galaxies form supermassive elliptical galaxy.

And although determine which category applies to one or another galaxy for scientists seems a fairly simple task, astronomers from time to time encounter galaxies most odd and bizarre shapes that can not be adjusted to the specific category. One of such cases, for example, is the galaxy ESO 149-3, located on the photo above.

This structure is an excellent example of the so-called astronomers wrong galaxy . This means that these galaxies do not have distinct forms in its internal structure, but rather like a large accumulation of randomly floating stars. According to statistics, about 25 percent of all the galaxies in space are irregular in shape.

The image above was made space telescope “Hubble” and shows a lack of internal structure, core or hoses related to ESO 149-3. The beauty of this picture lies in the fact that despite the presence of a key figure in the face of ESO 149-3, hit him several tens (if not hundreds) of other galaxies.
