Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. In December, NASA's third Great Observatory is planned for launch. The two NASA Great Observatories currently in orbit are the Hubble Space Telescope and the Compton Gamma-Ray Observatory , both now named for famous scientists . If your submitted suggestion conforms with contest rules and is chosen, you will have named the most powerful X-ray satellite ever built, and may even win a prize. This should allow AXAF the ability to see X-rays emitted near small black holes , from distant active galaxies , and inside huge clusters of galaxies .
Astronomers now hope for an uneventful launch, routine operations, and spectacular discoveries.
