3-panel of Detail Around the Galactic Center Region
In this image of the region around the Galactic Center, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the Milky Way galaxy is located within the bright white region to the right of and just below the middle of the image.

Galactic Center Region in X-rays from Chandra
X-rays detected by the Chandra X-ray Observatory expose a wealth of exotic objects and high-energy features. In this image, pink represents lower energy X-rays and blue indicates higher energy. Hundreds of small dots show emission from material around black holes and other dense stellar objects. A supermassive black hole - some four million times more massive than the Sun - resides within the bright region in the lower right. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions. This central region is the most energetic place in our galaxy.

Galactic Center Region in Infrared from Spitzer
The Spitzer Space Telescope's infrared-light observations provide a detailed and spectacular view of the galactic center region. The swirling core of our galaxy harbors hundreds of thousands of stars that cannot be seen in visible light. These stars heat the nearby gas and dust. These dusty clouds glow in infrared light and reveal their often dramatic shapes. Some of these clouds harbor stellar nurseries that are forming new generations of stars. Like the downtown of a large city, the center of our galaxy is a crowded, active, and vibrant place.

Galactic Center Region in Near-Infrared from Hubble
Although best known for its visible-light images, the Hubble Space Telescope also observes over a limited range of infrared light. The galactic center is marked by the bright patch in the lower right. Along the left side are large arcs of warm gas that have been heated by clusters of bright massive stars. In addition, Hubble uncovered many more massive stars across the region. Winds and radiation from these stars create the complex structures seen in the gas throughout the image. This sweeping panorama is the sharpest infrared picture ever made of the galactic center region.

Composite Images of Galactic Center Region
The spectacular composite image combines observations using infrared light and X-ray light that see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the galaxy is located within the bright white region on the lower right-hand side of the image (annotated on the labeled image). Each telescope's contribution is presented in a different color. Yellow represents the near-infrared observations of Hubble. Red represents the infrared observations of Spitzer. Blue and violet represent the X-ray observations of Chandra.
