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.
