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.

This illustration shows the rings of Saturn, an example of a disk that is very familiar to us. The material in this disk loses very little energy because of friction. Therefore, compared to a black hole such as GRO J1655-40, the disk is very stable, and is much cooler and fainter. (Illustration: NASA/CXC/M.Weiss)

Hubble Space Telescope ultraviolet observations made during the Chandra monitoring period of Jupiter showed relatively weak ultraviolet flaring. The combined Chandra and Hubble data indicate that the auroral activity was caused by the acceleration of charged ions of oxygen and other elements trapped in the polar magnetic field high above Jupiter's atmosphere. Hubble observed Jupiter for one-and-a-half hours on February 26, 2003. (Credit: NASA/STScI)

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)....

This illustration shows the absorption of X-rays from the quasar Mkn 421 by two intergalactic clouds of diffuse hot gas. These distant clouds (located 150 million and 370 million light years from Earth), are likely part of a predicted diffuse web-like system of hot gas clouds - the cosmic web - from which galaxies and clusters of galaxies are thought to have formed. This discovery is strong evidence that atoms and ions known to be present shortly after the Big Bang, but missing in inventories...

Chandra's observation of the hot halo surrounding the optical disk of NGC 5746 should help astronomers better understand how galaxies form. Spiral galaxies are thought to form from enormous clouds of intergalactic gas that collapse to form spinning disks of stars and gas. The Chandra data and computer simulations show that the likely origin of NGC 5746's hot halo is the gradual inflow of intergalactic matter left over from the formation of the galaxy.

The jet in Circinus X-1 is helping astronomers better understand how neutron stars, and not just black holes, can generate powerful beams. Many jets have been found originating near black holes (both the supermassive and stellar-mass variety), but the Circinus X-1 jet is the first extended X-ray jet associated with a neutron star in a binary system. This detection shows that the unusual properties of black holes -- such as presence of an event horizon and the lack of an actual surface -- may...

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:

Using Chandra spectra obtained from more than 300 supermassive black holes in the centers of galaxies, a team of astronomers has been able to determine the amount of iron near the black holes. The black holes were all located in the North [ http://chandra.harvard.edu/photo/2003/goods/index.html ] and South [ http://chandra.harvard.edu/photo/2003/goods/more.html ] Chandra Deep Fields, where the faintest and most-distant X-ray objects can be identified.

This image from the 1.3m McGraw-Hill shows 3C58 in visible light compared with Chandra's X-ray data of the same field of view. The optical image was taken on January 13, 2004. Scale:

MPEG This video zooms into the C153 spiral galaxy found in the galaxy cluster Abell 2125. The initial view moves from the NOAO telescope wide-field mosaic into the Hubble Wide Field Planetary Camera 2 image of C153. The Hubble image then dissolves into the composite detail of X-ray, radio and optical images. [Run time = 0:08 sec] -->

These images show the region of space around two rapidly rotating neutron stars in the Crab Nebula (left) and the Vela (right) supernova remnants. A magnetized, rapidly rotating neutron star produces electric voltages of several quadrillion volts. Particles are pulled off the neutron star and accelerated to speeds near the speed of light. A blizzard of electrons and anti-matter electrons, or positrons, is produced by these particles. The jets, and rings are thought to be caused by this process....

A Chandra image of neutron star KS 1731-260, remarkably cool after 12 years of being bombarded with hot gas from a companion star, not visible here. The now dim KS 1731-260 is the light blue object slightly above the midline of this image. (Credit: NASA/Chandra/Wijnands et al.)
