Bow Shock Near Young Star LL OriNASA's Hubble Space Telescope (HST) looks at the Great Nebula in Orion. One such jewel is this bow shock around the very young star, LL Ori.
A String of 'Cosmic Pearls' Surrounds an Exploding Star
Two decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years.
Sagittarius Star Cloud
Stars come in all different colors. The color of a star indicates its surface temperature, an important property used to assign each star a spectral type. Stars of this Sagittarius Cloud lie towards the center of our Galaxy - tantalizing cosmic jewels viewed through a rift in the dark, pervasive, interstellar dust. This famous stellar grouping houses some of the oldest stars known.

Kepler's Supernova Remnant SN 1604
The composite view of the supernova splits into its three components: blue-green for Chandra, yellow for Hubble, and red for Spitzer. Each observatory's full image is then shown for side-by-side comparison, beginning with Chandra, then Hubble, and finally Spitzer.

Edwin Hubble at Mt. Wilson
Albert Einstein and Edwin Hubble in 1931 at the Mount Wilson Observatory 100" telescope, in the San Gabriel Mountains of southern California. It was here in the 1920's that Hubble studied the cosmic expansion of the universe.
