+ - "Laser Mirror" Could be Future of Space Telescopes-> 1

Submitted by sciencehabit
sciencehabit (1205606) writes "Imagine a space telescope the size of a football field that weighs as much as a few slices of bread. Researchers have taken a step toward that goal by creating a small mirror out of tiny polystyrene particles, held together by lasers. Without any weight constraints, telescopes could be much more powerful than previously thought possible. In space, a series of powerful lasers would hold the mirror together, creating giant telescopes that weigh only a few hundred grams. What's more, such telescopes could quickly reassemble if struck by space debris."

    Meteorites don't fly and the Hubble hasn't been hit by many. Jupiter is it's protector
