Say goodbye to the neighborhood! On this hypothetical world near thecenterof the Milky Way, the planet's sun paints the sky purple as descendstowardthe horizon at left. However, the bright supernova exploding at upperrightlends an ominous feeling because its radiation is about to wipe out thealien life on this world. The galactic center is so dense with bright,hotstars that several can be seen through the cloudy twilight sky. (David A. Aguilar, CfA) JPEG (106K) High Resolution JPEG (1.6M)
	The Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) is the only observatory in the world able to make large-scale maps of the sky at submillimeter wavelengths. Data from AST/RO demonstrated that the center of the Milky Way galaxy is sterilized by frequent starbursts and the subsequent supernova explosions.
