A Cerro Tololo Sky
Explanation: High atop a
Chilean
mountain lies one of the premier observatories of the southern sky: the
Cerro Tololo Inter-American Observatory
(CTIO).
Pictured above
is the dome surrounding one of
the site's
best known instruments, the
4-meter Blanco Telescope
. Far behind the dome are thousands of individual stars and diffuse light from three galaxies: the
Small Magellanic Cloud
(upper left), the
Large Magellanic Cloud
(lower left), and our
Milky Way Galaxy
(right). Also visible just to Blanco's right is the
famous superposition
of four bright stars known as the
Southern Cross
. A single 20 second exposure, this digital image was recorded with a sensitive detector intended for astronomical imaging.
