Neutron Stars/X-ray Binaries
 |  | Animation and Composite Image of Crab Nebula
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). |

Sequence of images of J0617 in IC 443
QuicktimeMPEG
Beginning with a wide-field view of the supernova remnant IC 443, this sequence moves into a closer look at the neutron star embedded within known as J0617. The images show these objects in X-rays (blue), radio (green), and optical (red). The location and orientation of J0617's wake are mysterious for astronomers who would have expected it to be aligned toward the center of IC 443.

Tour of Crab Nebula
QuicktimeMPEG
In 1054 A.D., a star's death in the constellation Taurus was observed on Earth. Now, almost a thousand years later, a superdense neutron star left behind by the explosion is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula. This image combines data from Hubble, Spitzer and Chandra telescopes. The size of the X-ray image is smaller than the others because ultrahigh-energy X-ray emitting electrons radiate away their energy more quickly than the lower-energy electrons emitting optical and infrared light. By studying the Crab Nebula, astronomers hope to unlock the secrets of how similar objects across the universe are powered.

Animation of White Dwarf Gravitational Wave Merger
QuicktimeMPEG
This artist concept depicts two white dwarfs called RX J0806.3+1527 or J0806, swirling closer together, traveling in excess of a million miles per hour. As their orbit gets smaller and smaller, leading up to a merger, the system should release more and more energy in gravitational waves. This particular pair might have the smallest orbit of any known binary system. They complete an orbit in 321.5 seconds - barely more than five minutes.

Black Hole Devours a Neutron Star
QuicktimeMPEG
Scientists say they have seen tantalizing, first-time evidence of a black hole eating a neutron star-first stretching the neutron star into a crescent, swallowing it, and then gulping up crumbs of the broken star in the minutes and hours that followed.

Colliding Binary Neutron Stars
QuicktimeMPEG
Gamma-ray bursts are common, yet random, and fleeting events that have mystified astronomers since their discovery in the late 1960s. Many scientists say longer bursts (more than four seconds in duration) are caused by massive star explosions; shorter bursts (less than two seconds in duration) are caused by mergers of binary systems with black holes or neutron stars. This animation portrays one possible scenario that could produce the shorter bursts. While uncertainty remains, most scientists say in either scenario a new black hole is born.

Dissolve from Optical to X-ray Image of Westerlund 1
QuicktimeMPEG
This sequence begins with an optical view of the star cluster, known as Westerlund 1. When the view dissolves into Chandra's X-ray image, the unusual neutron star -- a dense whirling ball of neutrons about 12 miles in diameter -- appears very brightly.

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.

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.

Zoom to 47 Tucanae
QuicktimeMPEG
This animation zooms from ground-based optical views around the southern constellation of Tucana, to an ESO/Danish 1.54-m optical image of the globular cluster 47 Tucanae, and finally rests on the X-ray image of the cluster's core taken with Chandra.
