Visual Description: Galactic Center

A vibrant X-ray, optical, and infrared image showcases the Galactic Center of our Milky Way. The image is dominated by electric shades of blue, purple, pink-red and yellow-orange, which create an eye-catching contrast that fills the screen.  The image showcases the intricate structure of the Milky Way's Galactic Center, which is filled with various celestial objects such as stars, nebulae, and dust clouds.  Observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. The center of the galaxy is located within the bright white region to the right of and just below the middle of the image. Yellow-orange represents the near-infrared observations of Hubble. They outline the energetic regions where stars are being born as well as reveal hundreds of thousands of stars.
Red represents the infrared observations of Spitzer. The radiation and winds from stars create glowing dust clouds that exhibit complex structures from compact, spherical globules to long, stringy filaments. Blue and purple represent the X-ray observations of Chandra. X-rays are emitted by gas heated to millions of degrees by stellar explosions and by outflows from the supermassive black hole in the galaxy's center. The bright blue blob on the left side is emission from a double star system containing either a neutron star or a black hole.
