Astronomy, Dark Matter | featured news

That wonder molecule of life on Earth, DNA, is now being enlisted in the search for an exotic species zooming through the cosmos: dark matter... As far back as the 1930s, astronomers watching distant galaxies saw that something was missing: There were not enough stars to account for the heavy gravity needed to whirl galaxies so quickly or smash them together so swiftly.

Scientists’ predictions of the formation and characteristics of dark matter are shaken by research into dwarf galaxies surrounding the Milky Way.

Researchers have developed a simple geometrical method to add weight to the idea that ours is a flat, dark-energy-rich Universe.

Theoretical calculations done by astrophysicists at the Hebrew University in Jerusalem led by Professor Avishai Dekel, show that low mass galaxies can form when intergalactic gas streams into dark matter haloes and not by intergalactic gas heated by a virial shock to millions of degrees.
