This week, the National Science Board recommended proceeding to the final design stage for the Large Synoptic Survey Telescope (LSST), a telescope with a 330-inch mirror to be located in Chile, which will survey over half of the sky. Penn State has been a member of the LSST project since 2005. "The data that LSST will gather during its ten years of operation will offer us an unprecedented view of the universe, and will allow us to investigate important questions ranging from charting unknown objects in our own solar system to the large-scale structure of the universe and the nature of dark energy and dark matter," said Lawrence Ramsey, a member of the LSST Board of Directors as well as a Professor of Astronomy and Astrophysics and an Eberly College of Science Distinguished Senior Scholar at Penn State.

The LSST project is an international collaboration of 36 institutions, and will cost $665 million to build. Construction and commissioning of the telescope are expected to take seven years. "The heart of the LSST is a 3-billion-pixel, specially designed camera the size of a small car that can obtain a deep image of the sky covering an area of 50 full moons," remarked Niel Brandt, Distinguished Professor of Astronomy and Astrophysics at Penn State and the Chair of the LSST's Active Galactic Nuclei Science Collaboration. The large size of the telescope and the wide field of view of the camera allow the LSST to cover the entire available sky every few days. Two of the many scientific programs enabled by this frequent viewing of the sky are the identification of "Near Earth Asteroids," bodies whose orbits indicate that they could collide with the Earth; and the identification of transient sources in the distant universe, such as supernova explosions and the tidal shredding of stars by supermassive black holes.

"The LSST will bring about a revolution in our understanding of the cosmos," noted Brandt. "We cannot even begin to imagine all the insights that we will gain from the observations."

The announcement from the National Science Board is online here. Additional information about the LSST is on the project's website.
