The Dark Matter Core Defies Explanation in Hubble Image

Astronomers using data from NASA’s Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision. Abell 520 is a gigantic merger of galaxy clusters located 2.4 billion light-years away.

New Study Suggests that Universe Expanded Rapidly

A new study found that cosmic inflation, which was first proposed in 1980, is the simplest explanation that fits the measurements of the distribution of matter throughout the universe made by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), a spacecraft that scans radiation left over from the Big Bang. According to inflation, the universe expanded by a factor of at least 1078 (that’s 10 with 78 zeroes after it), all in less than a second.
