1. Tour of GRS 1915
QuicktimeMPEG We start with an optical and infrared image that shows the crowded area around the object known as GRS 1915+105, or GRS 1915 for short. Next is a close-up of the Chandra image of GRS 1915, which is located near the plane of the Milky Way. GRS 1915 is a so-called micro-quasar that contains a black hole about fourteen times the mass of the sun, which in turn is pulling material off a nearby companion star. With its high-energy transmission grating, Chandra has observed GRS 1915 eleven times since 1999. These studies reveal that a jet from the black hole in GRS 1915 may be periodically choked off when a hot wind is driven off the disk surrounding the black hole. Conversely, once the wind dies down, the jet can re-emerge. These results suggest that this type of black hole may have a mechanism for regulating the rate at which it grows.

2. Tour of M81
QuicktimeMPEG This image of the mammoth spiral galaxy M81, located about 12 million light years away, contains data from four different NASA satellites. First we see infrared data from the Spitzer Space Telescope, followed by optical data from the Hubble Space Telescope. The Galex Satellite shows us what M81 looks like in ultraviolet emission. And finally, x-ray data from the Chandra X-ray Observatory reveals what is going on at higher energies. At the center of M81, there is a supermassive black hole that is about 70 million times more massive than the sun. A new study involving Chandra and other telescopes helps astronomers better understand how this black hole is growing.

3. Images of M33 X-7
QuicktimeMPEG This sequence begins with a wide-field optical image from Kitt Peak of M33, a spiral galaxy about 3 million light years from Earth, and then zooms into a view from the Gemini telescope on Mauna Kea, Hawaii. Next, the view zooms into an even smaller field, from the Hubble Space Telescope, that includes M33 X-7, the most massive known black hole to be formed from the collapse of a star. The final image is a composite of the region around M33 X-7 that contains both the Chandra and Hubble data.

This sequence shows four black holes from the Bootes field. The first two black holes are obscured by thick rings of gas. Because such a ring blocks certain types of radiation, these black holes are only are seen in X-ray (blue) and infrared (red) light. The last two black holes are not enshrouded by this ring of material, and, therefore, emit X-ray, infrared, and optical (green) radiation. These objects helps astronomers better understand the properties of these monster black holes.

This animation depicts an eruption caused by a supermassive black hole. Gas and dust (reddish-brown disk) are being pulled around by the enormous gravity of the supermassive black hole, which is buried in the center of a large elliptical galaxy. The animation then zooms out to show the full view of the galaxy, which is surrounded by hot gas (red) that pervades the galaxy cluster. White jets, fueled from material falling onto the black hole, then erupt from the black hole and push gas backwards to create the dark cavities in the cluster gas.

This simulation illustrates the evolution of a magnetized jet of high-energy particles as it moves at near the speed of light through a low-density gas. Scientists believe that the western jet in XTE J1550-564 developed its cometary shape by a similar process.

This time-lapse movie made from observations over a four-year period shows the black hole XTE J1550-564 (center), the approaching eastern jet, and the receding western jet (right). In four years the jets moved about two light years from the black hole.

This animation begins by looking at the exterior of an elliptical galaxy. It then zooms into the region near the galaxy's massive central black hole. The sequence then shows how powerful jets of high-energy particles emanate from the vicinity of the black hole. These jets heat gas around the galaxy and stop the infall of matter into the galaxy, thereby limiting the galaxy's growth. This is what astronomers believe is happening in the cases of 4C41.17 and 3C294.

This animation begins with a view outside of Milky Way and then zooms in on one of the spiral arms to the double-star system XTE J1550-564, which contains a black hole and a normal Sun-like star. 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.
