Dark Matter Galaxies

When it comes to space, Mark Twain's statement that the "Truth is more of a stranger than fiction" is becoming more and more of an understatement. Recently a galaxy composed entirely of dark matter has been discovered which has some astronomers scratching their heads.

(Universe Today) Astronomers think they might have found a "dark galaxy", that has no stars and emits no light. Although the galaxy itself, located 50 million light years from Earth, is practically invisible, it contains a small amount of neutral hydrogen which emits radio waves. If astronomers are correct, this galaxy contains ten billion times the mass of Sun, but only 1% of this is hydrogen - the rest is dark matter. [...]

The team have looked at many other possible explanations, but have found that only the Dark Galaxy theory can explain all of the observations. As Professor Mike Disney of Cardiff University puts it, "The new observations make it even harder to escape the conclusion that VIRGOHI 21 is a Dark Galaxy."

The most common perception of galaxies seems to have been shattered, as apparently not all galaxies are lit by celestial lights. The international team led by astronomers from the National Science Foundation's Arecibo Observatory (as well as from the Cardiff University in the United Kingdom) are excited with the discovery and plan on searching for more of these dark mysterious behemoths.
