This magnificent image of a spiral galaxy shows how these galaxies have central regions containing older and more red and yellow stars. In the spiral arms, stars are being born all the time, and therefore these arms contain more blue stars - and also large amounts of dust.

This image shows a small portion of a nebula called the Cygnus Loop. Covering a region on the sky six times the diameter of the full Moon, the Cygnus Loop is actually the expanding blastwave from a stellar cataclysm - a supernova explosion - which occurred about 15,000 years ago.

Massive newborn stars are creating in this dramatic torn apart image of the Trifid Nebula.The Trifid Nebula is home to many thousands of newly created stars. The source of the jet is a young very hot star buried in the cloud.

This is a stunning picture of the most famous stellar factory. In the Orion Nebula hundreds of stars are being born, or are in the early stages of their infancy. Most fascinating is the discovery of small planetary systems being formed around some of the stars in this nebula.

This image shows a dark interstellar cloud ravaged by the passage of Merope, one of the brightest stars in the Pleiades star cluster. Just as a torch beam bounces off the wall of a cave, the star is reflecting light from the surface of pitch-black clouds of cold gas laced with dust. As the nebula approaches Merope, the strong starlight shining on the dust decelerates the dust particles. The nebula is drifting through the cluster at a relative speed of roughly 11 kilometres per second.
