Dark matter overwhelms

A distant dwarf galaxy has been discovered using a clever technique called gravitational lensing.

The strange and distant galaxy has been recorded to be 10bn light years away and is mysteriously largely consisted of dark matter an unkown phenomena to science. This dwarf of a galaxy could be a satellite of our galaxy.

"According to the theory of galaxy formation, you'd expect thousands of these satellites," described lead author of the study Simona Vegetti of the Massachusetts Institute of Technology.

Another of her study stated that "But if you look at the Milky Way we only find 30, so it's important to understand how many satellites are really there, and important to look at other galaxies other than the Milky Way,"

That will help confirm if our cosmic neighbourhood of galaxies - the Local Group - is strange, or if the theory of galaxy formation is incomplete.
