Spiral galaxies make up about 70 percent of all observed galaxies, some with large central bulges and tightly wound spiral arms like a fast-spinning ice skater, some with more wide-open arms and smaller bulges and some in various in-between states. NGC 2008, seen here in an image captured by the Hubble Space Telescope, is an Sc galaxy, with S signifying its spiral form and c indicating a small central bulge. The galaxy, located about 425 million miles from Earth in the constellation Pictor, was discovered in 1834 by astronomer John Herschel.
This Hubble Space Telescope image shows globular cluster NGC 1783 in the Southern Hemisphere constellation of Dorado. NGC 1783 lies within the Large Magellanic Cloud, a satellite galaxy of our Milky Way, some 160,000 light-years from Earth. NGC 1783 is thought to be less than 1.5 billion years old — very young for a globular cluster.
