MessageToEagle.com - A vast structure of satellite galaxies and
clusters of stars surrounding our Galaxy, stretching out across
a million light years has been discovered by astronomers from
the University of Bonn in Germany . The work challenges the
existence of dark matter, part of the standard model for the
evolution of the universe. PhD student and lead author Marcel
Pawlowski reports the team’s findings in a paper in the journal
Monthly Notices of the Royal Astronomical Society. The Milky
Way, the galaxy we live in, consists of around three hundred
thousand million stars as well as large amounts of gas and dust
arranged with arms in a flat disk that wind out from a central
bar. The diameter of the main part of the Milky Way is about
100,000 light years, meaning that a beam of light takes 100,000
years to travel across it. A number of smaller satellite
galaxies and spherical clusters of stars (so-called globular
clusters) orbit at various distances from the main Galaxy.
