Document Summary
For centuries astronomers and scientist have been observing the sky with a naked eye, up until the invention of a telescope. Using the telescope individuals have been able to discover and look at the events that take place beyond our home planet. Ever since the invention of a telescope astronomers have been building even larger telescope and more powerful than ever, giving them images of events that scientists only would have dreamed about witnessing. The new telescopes are much larger and provide crystal clear views of stars and galaxies which are located million if not billions of light years away. During the 2014 meeting which took place in. January the american astronomical society discovered an enormous spot in the sky, which is seen through a lens which is more than 500 000 light years wide. But the lens is actually a massive cluster of galaxies called the abell 2744.
