Oops! I got it wrong and had to re-edit this post. Well, I’ve decided to write here even though I may not be able to create the pdf ezine anymore (at least for some period of time).

I just read that there exists more dark matter dominated tiny galaxies surrounding our own Milky Way than previously thought. Since these ‘invisible’ galaxies are difficult to find, the theory that these should exist around big ones was more a mystery until this new find. The find came from astronomers Dr. Marla Geha and Dr. Josh Simon at W. M. Keck Observatory in Hawaii by studying previously discovered dwarf galaxies. They closely observed 814 stars in eight such dwarf galaxies first discovered with the Sloan Digital Sky Survey.

My say: “The cold dark matter theory is heading North! 😉 “
