Mass map shines light on dark matter
Lemont IL (SPX) Jul 16, 2015
Dark matter may find it tougher to hide in our universe. An international team of researchers has developed a new map of the distribution of dark matter in the universe using data from the Dark Energy Survey (DES). The DES, underway at the Blanco telescope in Chile, is a cosmological galaxy survey that will map approximately an eighth of the visible sky. The primary aim of the DES is to better characterize dark energy - the source of the observed accelerated expansion of the universe. But one of t ... read more

What happens when cosmic giants meet galactic dwarfs? When two different sized galaxies smash together, the larger galaxy stops the smaller one making new stars, according to a study of more than 20,000 merging galaxies. The research also found that wh ... more		Revealed: Positronium's behavior in particle billiards Collision physics can be like a game of billiards.
