natural phenomena in space

1. Collision Between Galaxies

Apparently galaxies can also eat each other. Even more surprising is the Andromeda galaxy is moving closer to our own Milky Way galaxy, and the picture above it is a simulation of colliding galaxies.

2. Quasar

Quasar glistened on the edge of the universe that we can see. Quasars release energy equivalent to the energy of hundreds of galaxies combined. It could be that quasars are a very large black hole in the hearts of distant galaxies. This image is the quasar 3C 273, which was photographed in 1979.

3. Dark Matter (Dark Matter)

Scientists think that dark matter (dark matter) is the largest constituent of the universe, but can not be seen and detected directly by current technology. Candidates range from heavy neotrino to invisible black holes.
