Halo stars in Andromeda Galaxy
Halo stars in Andromeda Galaxy (M31), Hubble Space Telescope (HST) image. Spiral galaxies, like M31, have a spherical halo of stars surrounding them. The stars in the halo are less densely packed than in the spiral arms or nucleus (neither seen). This view shows a small part of the halo, containing an estimated 300, 000 stars. Also seen, are distant galaxies and a globular cluster (bottom centre). This is the first time M31's faint halo stars have been seen, allowing their ages to be estimated and providing evidence for past galactic collisions of the Andromeda Galaxy. Image created in May 2003, using the HST's Advanced Camera for Surveys (ACS).

Star birth in the early universe
Star birth in the early universe, artwork. This 1- billion-year-old universe is based on deep field observations by the Hubble Space Telescope. Deep field observations reveal the remotest objects in the universe. Because light has taken billions of years to reach Earth from these distances, these observations look back to the early history of the universe. Observations from 1995 and 1998 showed intense knots of bright blue-white stars, thought to be part of these primordial starburst galaxies that are too faint to be seen. The next generation of space telescopes will look further back in time to try and reveal this epoch of star formation.
