One theory is that this missing matter hides in a halo of hot gas around each galaxy.

In clusters, too, dark matter seems to form a massive halo around the bright parts.

Among other sources of such radiation, scientists have proposed that interactions between bits of dark matter (which make up a large fraction of the universe's mass but haven't yet been directly detected) in a halo around the galactic center may be creating the surplus gamma rays.

They argue that the brown dwarfs are in fact members of a much smaller spherical distribution of matter around the centre of the Galaxy, which they call the spheroid in order to avoid confusion with the extended dark halo.

Some are found in globular clusters, but most move in a huge cloud around the disk called the galactic halo, which has a luminous inner component defined by globular star clusters and other easily observable stars (with coronae of hot gas possibly expelled by supernovae and of high - velocity neutron stars) and an outer dark - matter component inferred from its gravitational impact on the Milky Way's spiral disk.

Fair, My Wii was hacked to shit until i converted my stuff to the Wii - U, haven't gotten around to hacking it yet but now that it's obsolete it's only a matter of time haha yeah i was a Sony guy right up to PS2, (never owned a regular Xbox because aside from Fable and the old Halo's Xbox sucked balls) but when PS3 came out it was heavily lacking games i cared about and any FF game that came out at the time was going to Xbox 360 so i stuck to that, plus all of my friends had a 360 and played Halo and Gears and what ever was out at the time.
