(PhysOrg.com) -- When NASA launched its Chandra X-ray observing telescope into orbit in 1999, astronomers didn`t know much about the galactic winds made of wispy, multi-million-degree gas clouds that stream out from normal galaxies like our own, because they are `diffuse, gentle and unspectacular` compared to far more dramatic emanations of starbursts, recalls astronomer Q. Daniel Wang of the University of Massachusetts Amherst.
