Already the Gum nebula has turned out to be a quite strong emitter in the extreme UV, and spreads across 140 degrees of the night sky at 540 angstroms. Astronomers had discovered a new window through which to observe the heavens.
Astronomers look for velocities that are only a few m/s. In a spectrum, this corresponds to a blueshift or redshift of a fraction of an angstrom - and such a small shift is very difficult, though not impossible, to see.
