DUST IN DEPTH The Planck satellite analyzed the same patch of sky, shown here within the white dots, that the BICEP2 telescope measured in a search for primordial gravitational waves. Yellow and red patches contain the most galactic dust.
Astronomy news: NASA's Spitzer Images Out-of-This-World Galaxy The galaxy, called NGC 1097, is located 50 million light-years away. It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars.
