Near collision creates a bridge of gas between Andromeda and
another galaxy  Astronomers have confirmed that a bridge of
hydrogen gas is streaming between the giant Andromeda Galaxy and
its smaller neighbor, the Triangulum Galaxy. The connection is
likely the result of a cosmological close call between the two,
a discovery that will help scientists better understand the
evolution of galaxies.  This discovery was actually made in 2004
by using the Westerbrook Synthesis Radio Telescope in the
Netherlands, but it was strongly disputed by some scientists who
questioned the findings on technical grounds. But now,
astronomers working out of the National Radio Astronomy
Observatory (NRAO) have confirmed that a bridge of gas between
the two galaxies does indeed exist. By using the highly
sensitive Green Bank Telescope (GBT), these astronomers were
able to conduct a more thorough analysis that revealed six dense
clumps of gas in the stream.  Near collision creates a bridge of
