The Hubble space telescope is the best man-made telescope to mankind.  It can  track to up to 2 billion miles into the universe. When It was first launched into space, the  photos that were coming back were all blurry, and the scientists didn't know what was happening. After a while, they found that the lens were a 1/50th of a millimeter out of alignment, and that was why  they were all blurry. Astronausts went up there too fix it and it has been up there ever since 1950's
