Scientists Map The Dark Matter Around Millions Of Galaxies

This week, scientists with the Dark Energy Survey (DES) collaboration released the first in a series of detailed maps charting the distribution of dark matter inferred from its gravitational effects. The new maps confirm current theories that suggest galaxies will form where large concentrations of dark matter exist.

Brilliant new computer simulation shows how the Milky Way formed after the Big Bang

As surprising as this may sound, physicists and astronomers aren't entirely sure how spiral galaxies like the Milky Way got their exact shape. Any attempts to generate a spiral galaxy from scratch resulted in a computer simulation that showed a giant ball with too many stars. But a new study to be published in the… »7/26/12 12:30pm
