Description:
On April 27, 1961, NASA launched Explorer 11, a satellite that contained the first gamma ray telescope to go to space. <br/><br/>This marked the birth of space-based gamma ray astronomy. Gamma rays are a form of electromagnetic radiation and have the highest energy of any kind of wave in the electromagnetic spectrum. These waves come from things like supernova explosions, supermassive black holes, and even solar flares. Before Explorer 11 launched to look for gamma rays in space, scientists were pretty sure that gamma rays were out there. However, they had to way of detecting these gamma rays, because they get absorbed in Earth's atmosphere. Explorer 11 detected 22 cosmic gamma rays during its seven-month mission. These rays were coming from all over the place and didn't seem to point to any particular sources out in space. This observation became the first evidence of a uniform gamma-ray background in the universe.

Ariel 1 launched on an American Thor-Delta rocket from Cape Canaveral Air Force Station in Florida. It was also built at Goddard Space Flight Center in Maryland. Britain's Science and Engineering Research Council provided all of the experiments. Five of the six experiments on board studied the relationship between solar radiation and Earth's ionosphere, and one was dedicated to studying cosmic rays. Just 10 weeks after Ariel 1 launched, it was damaged by an explosion during a high-altitude nuclear test conducted by the U.S. military. Its solar panels broke, and it was unable to transmit any more useful data after that.")
