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.

Lenticular galaxy conceals an eventful past
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).
Hubble reveals chemical fingerprint of emission-line star
Showcased at the centre of this NASA/ESA Hubble Space Telescope image is an emission-line star known as IRAS 12196-6300 that lies some 2,300 light-years from Earth in the southern constellation of Crux. Under 10 million years old and not yet burning hydrogen at its core — unlike the Sun — this star is still in its infancy.
