NGC 604: Giant Stellar Nursery - About 3 million years ago in the nearby galaxy M33, a large cloud of gas spawned dense internal knots which gravitationally collapsed to form stars. NGC 604 was so large, however, it could form enough stars to make a globular cluster. (credit: Hubble Legacy Archive, ESA, NASA; Processing - Donald Waid)
The beautiful Trifid #Nebula is a cosmic study in colorful contrasts. Also known as M20, it lies about 5,000 light-years away toward the nebula rich #constellation #Sagittarius. A star forming region in the plane of our #galaxy, the Trifid Nebula is about 40 light-years across. -#Astronomy
This sharp cosmic portrait features NGC 891. The spiral galaxy spans about 100 thousand light-years and is seen almost exactly edge-on from our perspective. In fact, about 30 million light-years distant in the constellation Andromeda, NGC 891 looks a lot like our Milky Way. At first glance, it has a flat, thin, galactic disk and a central bulge cut along the middle by regions of dark obscuring dust.
