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 NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star. These rippling wisps of ionised gas, named DEM L316A, are the remains of an especially energetic Type Ia supernova located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbours — the Large Magellanic Cloud (LMC).
The elegant simplicity of NGC 4111, seen here in this image from the NASA/ESA Hubble Space Telescope, hides a more violent history than you might think. NGC 4111 is a lenticular, or lens-shaped, galaxy, lying about 50 million light-years from us in the constellation of Canes Venatici (The Hunting Dogs).
