Sky Eyes
Monday, December 17th, 2007Technology is nothing short of amazing. For the longest time the most amazing telescope in the world was the 200 inch Hale Telescope on Mount Palomar, in California. It taxed the technological infrastructure of the time to the max. It took, from start to finish, 21 years to make and revolutionized the astronomical world after the second world war. The mirror alone took 13 years to grind and polish and when it finally began operation in 1948 this telescope saw further into the universe than any instrument ever had.
Today we are riding the technology cusp at breakneck speed and astronomical innovations are again pushing the night sky envelope. A new generation of computer driven, multiple mirrored super scopes are on the drawing board. The largest, dubbed the overwhelmingly large (OWL) telescope has a series of mirrors that give it an effective diameter of 100 metres, a light gathering ability that is greater than all the major telescopes now in use combined! It has 4,000 times the area of the Hale telescope!
The new OWL, if and when it is constructed, will be able to peer right to the edges of our universe, see individual planets orbiting stars and cost more than a billion dollars to make. And it is so sensitive that it cannot be used without the most sophisticated software ever devised to cancel out the Earth’s atmosphere. Its foundations and the machinery that move it have to be impervious to the tiniest vibrations. Even a footstep would be enough to send out vibrations that could distort an image.
It will be the largest moveable piece of hardware ever created and is on the theoretical reaches of the materials used. Even if we wanted to build something larger, the limits to existing materials would prohibit the exercise. And it will take 20 years, from start to finish to build. But when it is completed it will create images that will revolutionize astronomy and what we know and understand of the universe. And no matter how we try, its virtually impossible to think of a way to pervert its use into something military or have an application other than to see, understand and learn.
