Animation and Composite Image of Crab Nebula. MPEG This sequence begins with an artist's animation of the explosion that produced the Crab Nebula, now an expanding debris field of extremely high-energy particles created from the death of a massive star. The view then fades into an image of the Crab composed of data from Chandra (light blue), Hubble (green and dark blue), and Spitzer (red). [Runtime: 0:18]

Frosty white water ice clouds and swirling orange dust storms above a vivid rusty landscape reveal Mars as a dynamic planet in this sharp image. The Earth-orbiting Hubble telescope snapped this picture on June 26, when Mars was approximately 43 million miles (68 million km) from Earth -- its closest approach to our planet since 1988. The disk of Mars was fully illuminated as seen from Earth because Mars was exactly opposite the Sun. Hubble can see details as small as 10 miles (16 km) across....

The image shows a dramatic bow-like structure at the leading edge of the cloud, or nebula, embedded in the Vela supernova remnant. As indicated by the arrow, the jets point in the same direction as the motion of the pulsar. The swept-back appearance of the nebula is due to the motion of the pulsar through the supernova remnant.

When a massive star explodes like the one that produced G292.0+1.8, it creates a shell of hot gas that glows brightly in X-rays. Chandra is able to observe the stellar debris, revealing the dynamics of the explosion. With nearly six days of Chandra observing time devoted to studying G292.0+1.8, astronomers hope they can use this particular remnant to better understand the complicated details of such an explosion. This image shows the high-energy X-rays only (1.810-2.050 and 2.400-2.620 keV)....

Spiral galaxies are thought to form from enormous clouds of intergalactic gas that collapse to form spinning disks of stars and gas.

Supernova 1987A occurred in the Large Magellanic Cloud, a galaxy only 160,000 light years from Earth. The outburst was visible to the naked eye, and is the brightest known supernova in almost 400 years. Optical hot-spots (pink-white) now encircle the ring like a necklace of incandescent diamonds. The Chandra data (blue-purple) reveals multimillion-degree gas at the location of the optical hot-spots.

This broadband Chandra X-ray image reveals dramatic details of a portion of the Crescent Nebula. Powerful winds blowing from the massive star, HD 192163, created this nebula. About 400,000 years ago, HD 192163 expanded enormously to become a red giant and ejected its outer layers at about 20,000 miles per hour. Two hundred thousand years later, the intense radiation from the exposed hot, inner layer of the star began pushing gas away at speeds in excess of 3 million miles per hour. Scale:

MPEG This sequence compares the physical size of the cavities found in MS 0735.6+7421 and the Perseus cluster, another well-known galaxy cluster with cavities. These two clusters are at very different distances -- Perseus is about 250 million light years away and MS 0735 is almost three billion light years away.
