    Astronomers have found a strange new species in the cosmic zoo: a microquasar that emits gamma rays. The rare beast would be a new source for gamma rays, which have even higher energies than x-rays. The finding suggests that microquasars have more power than astronomers knew.

    The older they get, the more Hollywood's stars tend to keep their age secret. In the universe, it's the other way around. Astronomers have the most trouble determining the age of young stars. But now, a team has found that an alcohol test may give them away.
