Hubble telescope snapshot: The face of the “ghost” in the far depths of outer space

What you see in the above picture is very similar to the face of some ghost from children’s horror stories. However, in fact, you see a region of space 704 million light-years distant from us where a large-scale event occurs – a collision of two galaxies. These two galaxies are precisely the “eyes of a ghost,” and the ring of clouds of cosmic dust and eyes give a common appearance to all this.

A picture of the collision of galaxies was taken by the Hubble Space Telescope in June this year, but NASA’s enterprising specialists published it last week, coinciding with the Halloween holiday and all other scary things. The system where the collision of galaxies takes place is called Arp-Madore, it is very interesting from a scientific point of view, not only because its appearance makes us see a human face in inanimate objects.

Two galaxies of the Arp-Madore system, having approximately equal sizes and mass, as if in slow motion, are sent directly to each other, following the course for a head-on collision. An interesting fact is that in the vast majority of cases of such collisions, galaxies of different sizes take part, as a result of which a large galaxy absorbs a small one, increasing in size.

The gravitational forces that trigger the collision pulled gas and dust from the bowels of both galaxies, which formed ring clouds surrounding the site of the collision. By a lucky coincidence in this case, the shape of these clouds makes our brain see the forehead, the line of the chin and nose, and, of course, the eyes are two bright galaxies.

This gas and dust halo will surround the collision site for at least 100 million years, and when two galaxies merge into one large galaxy in about one to two billion years, all the matter of these clouds will return to the boundaries of the new galaxy, thereby provoking a high level of “birth rate” of young stars on its outskirts.

In conclusion, we note that collisions of galaxies are very common in the universe. And even our galaxy, the Milky Way galaxy, is heading for a collision with the neighboring Andromeda galaxy, which will happen in about four billion years. First, these two galaxies will go through the stage of metamorphosis of their shape and, ultimately, merge into one large galaxy.
