MPEG This animation shows a supermassive black hole within a galaxy like the one located in NGC 1365. Scientists believe that the black hole at the center of the galaxy is fed by a steady stream of material, presumably in the form of a disk. Material just about to fall into a black hole should be heated to millions of degrees before passing over the event horizon, or point of no return. This process creates X-ray light that Chandra can detect. [Runtime: 0:27]

A dark dust lane, running to the south and east of the nucleus, is apparent in this 2MASS image, which covers the near-infrared portion of the spectrum. The disk of the galaxy, overall, is much fainter than the bright nucleus. Maiolino et al. propose, based on Hubble Space Telescope near-infrared NICMOS imaging, that this dust lane traces a nuclear gas bar that may be responsible for feeding the active nucleus. (Credit: S.

As gaseous material is pulled off the companion star onto the black hole, it forms a disk that is heated to millions of degrees. The animation then shows the ejection and evolution of the jets of high-energy particles.

Chandra's image of G292.0+1.8 shows remarkable complexity and structure in the debris field of this exploded star. Each color represents different elements such as oxygen, neon, magnesium, and silicon. The distribution of these elements gives astronomers clues about how the star exploded.

A long Chandra exposure of M87 has revealed a shock wave in high-energy X-rays as well as evidence for a series of outbursts from the central supermassive black hole. The image shows a series of loops and bubbles in the hot, X-ray emitting gas. These are relics of small outbursts from close to the black hole. Other remarkable features are seen in M87 for the first time including narrow filaments of X-ray emission, which may be due to hot gas trapped to magnetic fields. One of these filaments is...

Astronomers have located an exceptionally massive black hole - almost 16 times the mass of the Sun - in orbit around a huge companion star. By combining observations from NASA's Chandra X-ray Observatory with optical data from the Gemini telescope, the black hole known as M33 X-7 was determined to be the most massive black hole in its class. This result has intriguing implications for the evolution and ultimate fate of massive stars. (Credit: AURA/Gemini Obs./SDSU/J.Orosz et al.)

This illustration shows three possible futures for the Universe, depending on the behavior of dark energy, by showing how the scale of the Universe may change with time. If dark energy is constant, as the new Chandra results suggest, the expansion should continue accelerating forever. If dark energy increases, the acceleration may happen so quickly that galaxies, stars, and eventually atoms will be torn apart, in the so-called Big Rip. Dark energy may also lead to a recollapse of the Universe,...

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.

Artist's Conception of X-ray Binary System. An artist's conception shows a double star system with a normal Sun-like star in orbit around a black hole. As gaseous matter is pulled from the normal star, it forms a disk around the black hole and is heated to temperatures of millions of degrees. Intense electromagnetic forces in the disk can expel jets of high-energy particles. (Credit: NASA/CXC/M.Weiss)

This sequence of images shows a disk of red and yellow gas around a supermassive black hole. As the view pulls back, the formation of stars in the outer regions of the disk is seen. These massive stars form when the gas becomes unstable, despite the black hole's enormous gravitational influence, and collapses inwards.

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light years another with a diameter of 260 light years. In the Hubble image, the smaller inner ring is located on the inside of the green disk. The larger outer ring extends off the image and is in the plane of the galaxy's disk. This Hubble Space Telescope image of the Circinus Galaxy was taken on April 10, 1999 with the Wide Field Planetary Camera 2. (Credit:...

Cas A on Blue: This striking color rendition displays a wealth of detail and drama. Note the shock wave on the outer edge, and the blow-out on the upper left, as well as the enigmatic bright spot in the middle. The colors represent X-ray brightness (yellow = brightest, blue = background), not temperature. Credit: NASA/CXC/SAO (courtesy, C.Jones)

Images of Long Galaxy Tail. MPEG This sequence of images begins with a wide-field view of Abell 3627, a giant cluster of galaxies, as seen in X-rays by ESA's XMM-Newton observatory. The view then zooms into an area that shows the galaxy ESO 137-001 as it plunges toward the cluster. First shown in optical light (white) then hydrogen emission (red), the image then turns to the multimillion-degree gas observed NASA's Chandra X-ray Observatory. The final image is a composite of all of these data...

Sequence of Andromeda Galaxy (M31) Images. MPEG Beginning with a wide-field optical view, this sequence of Andromeda Galaxy images moves into an X-ray look of the central region. In this Chandra image, red represents lower energy, green as medium energy, and finally blue as the highest energy X-rays that Chandra detects. This sequence also shows a composite of X-ray and infrared light, before returning to the Chandra-only view. [Runtime: 0:14]

This Chandra X-ray image reveals a barrel-shaped supernova remnant around a glowing bar of intense X-radiation. These X-rays are produced by jets of 15 million degree Celsius gas that is rich in iron and nickel. These features indicate that W49B was produced when the core of a rapidly-rotating massive star collapsed to form a black hole, triggering the ejection of high-energy jets of material. Scale:

This illustration shows two spiral galaxies - each with supermassive black holes at their center - as they are about to collide. The latest Chandra results suggest that such collisions may cause extreme black hole and galaxy growth in the early Universe, setting the stage for the birth of quasars. (Credit: NASA/CXC/M.Weiss)

An artist's illustration depicts the sound waves (ripples) in the hot gas that fills the Perseus cluster. Key elements of the system are labeled in the version on the right. The ripple features were discovered by using a special image-processing technique to bring out subtle changes in brightness. These sound waves are thought to have been generated by cavities blown out by jets from a supermassive black hole (bright white spot) at the center of the Perseus cluster.

This remarkable Chandra image gave scientists their first look at X-rays from Mars. In the sparse upper atmosphere of Mars, about 120 (75 miles) kilometers above its surface, the observed X-rays are produced by fluorescent radiation from oxygen atoms. (Credit: NASA/CXC/MPE/K.Dennerl et al.)

MPEG This animation shows a yellow star that travels too close to a giant black hole in the center of the galaxy RX J1242-11. As it nears, the star is stretched by tidal forces from the black hole and is quickly torn apart. Most of the yellow gaseous debris from the star escapes the black hole in parabolic orbits. However, a small amount of material is captured by the black hole and then forms a rotating disk of gas. X-rays are emitted as the gas in the disk is heated (as shown by the blue...

MPEG The first illustration in this sequence shows a doomed star (orange circle) that wanders so close to a giant black hole that the black hole's enormous gravity stretches the star until it is torn apart. Some of the disrupted star's mass (indicated by the white stream) is swallowed by the black hole, while the rest is flung away into the surrounding galaxy. The second illustration shows how the gas that was pulled towards the black hole forms a disk and is heated before being swallowed by...
