With its additional seven smaller mirrors it is expected that the Giant Magellan Telescope will offer 10 times the resolution of the Hubble Space Telescope. Its optic precision is very accurate: "one part in 10 billion in terms of precision manufacturing,", as explained by project director Patrick McCarthy.
These incredibly tight tolerances have to be ensured in order not to lose information collected from light that travelled five, 10 billion light years. To avoid loss or information scramble and to compensate for various atmospheric disturbances the telescope will also employ adaptive optics.
The Giant Magellan Telescope will offer a better look in space. Scientists will be able to study more accurately everything from newly discovered planets located just outside our solar system to super-massive black holes.
