Narrator: This is Science Today. An astrophysicist at the University of California, Davis is leading the effort to build a new type of telescope that will provide digital imaging of faint objects across the sky. It's called the Large Synoptic Survey Telescope and astrophysicist Tony Tyson says the goal is to map matter that physicists say make up 95 percent of the Universe – the mysterious dark matter and dark energy.
Tyson: It's invisible, it doesn't emit any light, it doesn't absorb any light, you can't see it by virtue of its shadow. Big clumps of it basically have an over density of mass, and it deflects light from the distant universe, and it moves the positions of things in the distant universe. It's a kind of cosmic mirage.
Narrator: Tyson says the telescope will also track objects such as asteroids and huge bursts of energy.
Tyson: It opens up a new window on the universe.
Narrator: The Large Synoptic Survey Telescope, set for use in 2012, will also include the largest digital camera ever built – with three billion pixels. For Science Today, I'm Larissa Branin.
