Galaxy M81
The arms of the "grand design" spiral galaxy M81 are filled with young, bluish, hot stars. The greenish regions in the image are bright, gaseous clouds where new stars are forming.

Center of the Crab Nebula
At the center of the Crab Nebula sits a stellar remnant called a neutron star that has about the same mass as the Sun compressed into a sphere only a few miles across. Spinning 30 times a second, the neutron star shoots out beams of energy that make it look like it's pulsating

Jupiter
Jupiter's turbulent clouds are always changing as they encounter atmospheric disturbances while sweeping around the planet at hundreds of miles per hour. This image includes a dark, serpent-shaped structure that is actually a small tear in the cloud deck.

Supernova 1987A
This image shows the remnant of Supernova 1987A, a stellar explosion in a nearby galaxy that astronomers witnessed in 1987. A shock wave of material unleashed by the stellar blast is slamming into a surrounding ring of gas, causing it to glow.

Beta Pictoris Disk
In 1984, Beta Pictoris was the very first star discovered to be surrounded by a bright disk of light-scattering dust and debris. Planets are thought to form in such disks, and astronomers have discovered two planets orbiting Beta Pictoris.

Galaxy NGC 1672
NGC 1672 is a barred spiral galaxy. Its arms do not twist all the way to the galaxy's center but attach to the ends of a bar of stars that extends from the nucleus. Clusters of hot, young, blue stars form along the spiral arms, while surrounding clouds of hydrogen gas glow red.

Eagle Nebula Pillars
Hubble's view of the "Pillars of Creation" in the Eagle Nebula displays three giant columns of cold gas giving birth to new stars. The pillars are bathed in the scorching ultraviolet light from a cluster of young, massive stars beyond the top of the image.

Eskimo Nebula
The Eskimo Nebula contains the glowing remains of a dying Sun-like star. The bright, central region of the Eskimo's "face" is material being blown away by the nebula's central star.

Galaxy Cluster Abell 2261
The giant elliptical galaxy in the center of this image is the most massive and brightest member of galaxy cluster Abell 2261. More than a million light-years wide, the galaxy is about 10 times bigger than our Milky Way galaxy.

Hubble Ultra Deep Field
This image of the Hubble Ultra Deep Field includes infrared observations that allowed Hubble to peer deeper into the universe than it ever had before. The faintest and reddest objects in the image are galaxies that formed 600 million years after the big bang.

Interacting Galaxies Arp 148
Arp 148 is the aftermath of an encounter between two galaxies, resulting in a ring-shaped galaxy and an elongated companion. The shapes and arrangement of the galaxies suggest that this is a snapshot of an ongoing collision.
