1. Into the Milky Way: Quintuplet Cluster
QuicktimeMPEG This sequence begins with Chandra's X-ray view of a 900 by 400 light year swath of the center of the Milky Way. It then zooms into a smaller region where large filamentary structures are seen in radio waves. The view moves in even closer to show the Quintuplet star cluster. Named for its five brightest stars at infrared wavelengths, the Quintuplet is known to be home to hundreds of stars. Several of these are very massive stars that are rapidly losing gas from their surfaces in high-speed stellar winds. Collisions from these winds are what astronomers believe to be the source for the point-like concentrations seen in the Chandra image.

2. Towards the Milky Way: DB00-6
QuicktimeMPEG his series of images shows the DB00-58 star cluster in context with Chandra's 900- by 400-light year mosaic of the Galactic Center. The view then transitions to radio emission from a smaller region that includes DB00-6, before showing infrared data, and ending with Chandra's X-ray close-up. . Despite DB00-6's similar appearance to DB01-42 (#1, above), the X-ray and infrared information show that DB00-6 is, in fact, a foreground object, and is significantly closer to us than 25,000 light years.

The view then transitions to infrared emission from a smaller region that includes DB00-58, before showing Chandra's X-ray close-up. Despite DB00-58's similar appearance to DB01-42 (#1, above), the X-ray and infrared information show that DB00-58 is, in fact, a foreground object, and is significantly closer to us than 26,000 light years.

4. DB01-42 in context of the Milky Way Center
QuicktimeMPEG This series of images puts the cluster known as DB01-42 in context with Chandra's 900- by 400-light year mosaic of the Galactic Center. The view then transitions to radio emission from a smaller region that includes DB01-42, before showing infrared data of the same area, and ending with Chandra's X-ray close-up. Chandra's X-ray data have helped astronomers identify DB01-42 as a member of the Galactic Center. It is about 26,000 light years away from Earth.

8. Chandra's Many Views of the Center of the Milky Way
QuicktimeMPEG This sequence shows how astronomers are using Chandra to help probe the mysterious region at the center of the Milky Way. The first image is a 900- by 400-light-year mosaic in X-rays taken by Chandra. The view then zooms into a smaller region that encompasses the latest Chandra discovery of puzzling, extremely hot and diffuse emission. From there, the sequence shows two even smaller fields of view of the region surrounding the Milky Way's supermassive black hole, known as Sgr A*. The final element is an artist's conception of Sgr A* itself and its accretion disk as it undergoes a flare.

9. Time-lapse Movie of Galactic Center X-ray Binaries
QuicktimeMPEG This sequence of 5 images is part of an ongoing Chandra program that monitors a region around the Milky Way's supermassive black hole, Sgr A*. Four bright, variable X-ray sources were discovered within 3 light years of Sgr A*. The variability is indicative of an X-ray binary system where a black hole or neutron star is pulling matter from a nearby companion star. Such a high concentration of X-ray binaries in this region is strong circumstantial evidence that a dense swarm of 10,000 or more stellar-mass black holes and neutron stars has formed around Sgr A*. The swarm likely formed as stellar-mass black holes, and to a lesser extent, neutron stars, gradually sank toward the center of the Galaxy over the course of several billion years.

10. Sequence Showing Evidence of Black Hole Swarm in Context
QuicktimeMPEG The first image in this sequence is Chandra's 900- by 400-light year mosaic of the Milky Way's center. Next, the view zooms into a smaller region where Chandra has found some 2,000 individual X-ray sources. Finally, Chandra's view of the area immediately surrounding Sagittarius A* (Sgr A*), the Milky Way's supermassive black hole, is shown. As part of a long-term monitoring program, Chandra found several variable X-ray sources. This variability suggests these sources are in systems containing their own stellar-sized black holes.
