ALT A composite image of the center of our Milky Way Galaxy. Overall, it looks like an impressionist oil painting with patches of diffused color. At the heart of the image is a light purple cloud and a spiraling, bright yellow tangle. The purple cloud represents X-rays from the center of the supernova remnant. Inside the bright yellow tangle is Sagittarius A*. Surrounding the remnants of the exploded star and its black hole neighbor, is a neon red gas cloud with trails drifting toward our upper right. Here, red represents radio data from the NSF's Very Large Array. A faint, dark blue cloud, barely discernible against the blackness of space, begins at our upper left and exits the bottom of the frame. This is submillimeter-wavelength data from the James Clerk Maxwell Telescope. Mottled, faint patches of forest green stretch across the image from our lower left to our upper right. These are lower-energy X-rays detected by Chandra, possibly linked to past outbursts from Sagittarius A*.
