This video zooms in on Messier 77, or NGC 1068, a spiral galaxy in the constellation of Cetus, some 45 million light-years away from Earth. The sequence begins with a view of the night sky near Cetus, then zooms through observations from the Digitized Sky Survey 2, and ends with a view of the galaxy obtained by the Hubble Space Telescope. The streaks of red and blue in M 77 highlight pockets of star formation along the pinwheeling arms, with dark dust lanes stretching across the galaxy's starry center. The galaxy belongs to a class of galaxies known as Seyfert galaxies, which have highly ionized gas surrounding an intensely active center.
