Galactic Ridge in 60 Seconds
Narrator (Megan Watzke, CXC): This sequence begins with an infrared view from the Spitzer Space Telescope of the central region of the Milky Way. We then zoom into a region about 1.4 degrees away from the center of the galaxy where the Chandra X-ray Observatory focused its attention for about twelve days' worth of time. This region is known as the Galactic Ridge, because earlier X-ray observatories found a structure of diffuse emission stretching across the plane of the galaxy. The new long Chandra observation shows that this X-ray haze is actually composed of thousands of individual sources, like stars and binary systems.
