PASADENA, California (AP) -- Astronomers have completed the most thorough
high-resolution digital survey of the heavens and released its 5 million
images on the Internet.
The map of the sky took four years of observations and $40 million to
complete. It contains an estimated 500 million celestial objects, mostly
stars but also galaxies, asteroids and comets.
"The public will 'ooh and aah' at the pictures, while scientists will mine
the data for decades," Michael Skrutskie, principal investigator for the
project, said Thursday.
The project's twin telescopes, located in Arizona and Chile, mapped the sky
in the infrared part of the electromagnetic spectrum. Infrared wavelengths
are longer than the red light visible to human eyes.
Infrared radiation -- heat -- pierces the dust and gas that shrouds much of
the universe from view, allowing the telescopes to see objects that would
otherwise be invisible to view.
The University of Massachusetts Amherst led the Two Micron All-Sky Survey.
NASA and the National Science Foundation funded the project.
