Dark matter telescope, also handy for detecting those pesky asteroids
The possibility of repeatedly surveying large portions of the sky to unprecedented depth opens a range of opportunities, from detecting Earth-threatening asteroids to probing the nature of dark energy.
By combining a huge collecting area and a wide field of view the LSST telescope will be 20 times more powerful than any observatory now operating or under construction. The Large-aperture Synoptic Survey Telescope, often called the Dark Matter Telescope, is a proposed 8.4 meter, 7 square-degree field survey instrument which will have an effective aperture of 6.9 meters.
