The Omega
Nebula. M17,
also known as the Omega Nebula, the Swan Nebula, the Horseshoe Nebula,
or (especially on the southern hemisphere) the Lobster Nebula. It
is a star producing area that gets its light from the radiation
of young stars. From SEDS: "This (reddish) color comes from
the hot hydrogene gas which is excited to shine by the hottest stars
which have just formed within the nebula. However, the brightest
region is actually of white color, not overexposed as one might
think." The mass of this gas has been estimated to be around
800 times that of our Sun. It is estimated to be around 5000-6000
light years away.
