A new analysis of Hubble surveys, combined with simulations of galaxy interactions, reveals that the merger rate of galaxies over the last 8 billion to 9 billion years falls between the previous estimates.

Why Are Humans Primates? People may seem very different from lemurs, monkeys and apes, but all primates share a few key physical and behavioral characteristics Though the collision occurred in space, it dumped thousands of times more dust than usual into Earth's atmosphere for millions of years, leading to a gradual global cool-down.
