2006 Chandra X-Ray Observatory Photos
 
Composite image of the M87 galaxy. NASA's Chandra X-ray Observatory has located a gigantic sonic boom generated by a supermassive black hole. This musical discovery -- which included evidence for a cacophony of deep sound -- was made using data from the longest X-ray observation ever of M87, a nearby giant elliptical galaxy. The Marshall Center manages the Chandra program. + Read More

A composite image of supernova remnant RCW 86, using data from Chandra and XMM-Newton X-ray observatories. Using NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton Observatory, scientists have uncovered evidence to help confirm the identification of the remains of one of the earliest-recorded stellar explosions. The new study shows that the supernova remnant RCW 86 is younger than previously thought, with its formation appearing to coincide with a supernova observed by Chinese astronomers in 185 A.D. + Read More

Composite image of the galaxy cluster 1E 0657-56, also known as the 'bullet cluster.' Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. + Read More

These six galaxy clusters are among 38 that scientists observed with Chandra to help determine the Hubble constant.  The clusters’ distances range from 1.4 to 9.3 million light years from Earth. The Hubble constant, a critically important number that specifies the expansion rate of the universe, has been independently determined using NASA's Chandra X-ray Observatory.The result is significant, said the Marshall Center scientist who led the study, because the Hubble constant tells us the size of the universe, its age, and how much matter it contains. + Read More

A new Chandra X-ray image shows three massive star clusters near the enormous black hole at the center of the Milky Way Galaxy. The center of the Milky Way is a crowded neighborhood and not always a calm one, according to the latest image from NASA's Chandra X-ray Observatory. In addition to the supermassive black hole at the galaxy’s center, the area is filled with all sorts of different inhabitants that affect and influence one another. Those inhabitants include three massive star clusters that slam into the surrounding cooler, dense clouds of molecular gas. + Read More

Composite image of GRO J1655-40 The X-ray spectrum of a binary star system consisting of a black hole and a normal star indicates that turbulent winds of multimillion degree gas are swirling around the black hole. As the illustration shows, much of the hot gas is spiraling inward toward the black hole, but about 30% is blowing away. + Read More

A color-coded Chandra image shows the central region of the Andromeda Galaxy. A newly released image from NASA’s Chandra X-ray Observatory has revealed an X-ray emitting cloud of hot gas in the central region of the Andromeda Galaxy. A large spiral galaxy much like our Milky Way, Andromeda is relatively nearby and can be seen with binoculars in the autumn sky. + Read More

A newly released image of Supernova Remnant IC443 combines wide-field X-ray, radio and optical observations. The pullout, also a composite, shows a neutron star spewing out a comet-like wake of high-energy particles.

Dr. Martin Weisskopf Dr. Martin Weisskopf of the Marshall Center has received the George W. Goddard Award for scientific contributions to NASA’s Chandra X-ray Observatory, the world’s most powerful X-ray telescope. As the observatory’s project scientist, Weisskopf has dedicated nearly three decades of his career to the Chandra program. The Chandra X-ray Observatory Program is managed by the Marshall Center. + Read More

Chandra X-ray and VLA Radio image of NGC 4696 By studying the inner regions of nine elliptical galaxies with Chandra, scientists can now estimate the rate at which gas is falling toward the galaxies' supermassive black holes. These images also allowed them to estimate the power required to produce radio emitting bubbles in the hot X-ray gas. + Read More

Composite Chandra X-ray and radio image of the galaxy cluster Abell 400. NASA's Chandra X-ray Observatory has helped scientists better understand the interaction between two black holes in the galaxy cluster Abell 400. A composite X-ray and radio image of the galaxy shows radio jets originating from the vicinity of two supermassive black holes. Careful analysis of the Chandra and radio data indicates the galaxies and their supermassive black holes are indeed bound together by their mutual gravity. The Marshall Center manages the Chandra program. + Read More

An artist's illustration depicts a quasar in the center of a galaxy that is expelling gas at high speeds. The inset contains a Chandra X-ray image of the quasar 4C37.43. New data from NASA's Chandra X-ray Observatory may provide clues to how quasars "turn on." Quasars are born when gas flows into a black hole and releases a tremendous amount of energy. Since the discovery of quasars more than 40 years ago, astronomers have been trying to understand the conditions surrounding the birth of these immensely powerful objects. The Marshall Center manages the Chandra program. + Read More

Chandra and optical image of NGC 2841, a large spiral galaxy. Recent observations with NASA's Chandra X-ray Observatory have revealed new details about NGC 2841, a large spiral galaxy about 50 million light years from Earth. Revealing how galactic chimneys turn up the heat, the X-ray and optical image shows multimillion degree gas rising above the galaxy’s disk of stars and cooler gas. The Marshall Center manages the Chandra program. + Read More

Puppis A The three-color image of a region of the supernova remnant Puppis A, captured by the Chandra X-ray Observatory, reveals a cloud being torn apart by a shock wave produced in a supernova explosion. This is the first X-ray identification of such a process in an advanced phase. The Marshall Center manages the Chandra program. + Read More

Chandra and optical observations of the massive spiral galaxy NGC 5746. Scientists using NASA's Chandra X-ray Observatory have detected an extensive halo of hot gas around a spiral galaxy 100 million light years from Earth. The discovery is evidence that galaxies like our Milky Way are still accumulating matter from the gradual inflow of intergalactic gas. The Marshall Center manages the Chandra program. + Read More

Sample gallery of X-ray and optical images studied. Black holes are creating havoc in unsuspected places, according to a new study of elliptical galaxies. Analyzing 56 galaxies in the NASA Chandra X-ray Observatory data archive, astronomers discovered far-reaching explosive activity due to giant central black holes. This unsuspected turmoil belies the galaxies’ calm appearance in optical light. The Marshall Center manages the Chandra program. + Read More
