On April 27, 1961, NASA launched Explorer 11, a satellite that contained the first gamma ray telescope to go to space.
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.

00:04On April 27th, 1961, NASA launched Explorer 11, a satellite that contained the first gamma-ray telescope to go to space.
00:12This marked the birth of space-based gamma-ray astronomy.
00:15Gamma-rays are a form of electromagnetic radiation and have the highest energy of any kind of wave in the electromagnetic spectrum.
00:22These waves come from things like supernova explosions, supermassive black holes, and even solar flares.
00:27Before Explorer 11 launched to look for gamma rays in space, scientists were pretty sure that gamma rays were out there.
00:34However, they had no way of detecting these gamma rays because they get absorbed in Earth's atmosphere.
00:39Explorer 11 discovered 22 cosmic gamma rays during its seven-month mission.
00:44These rays were coming from all over the place and didn't seem to point to any particular sources out in space.
00:50This observation became the first evidence of a uniform gamma ray background in the universe.
00:54And that's what happened on this day in space.
00:57And that's what happened on this day in space.

01:05Fans are bright.
01:07That you think Golan maybe are at a time-bayern smarter than the background of cometula?
01:08This could do some of them.
01:10rethink theним Parents.
01:11Where does it know no they're in you?
01:12This could yapáºy.
01:14That's so bright.
01:15Mickey McStarkis gives such a good energy and this, so Mariura, the eyes, especially for change ideas.
01:18And that was absolutely wonderful.
01:20And that was a superpower.
01:22You have been very rich.
01:23That's it.
01:25Remember myeker's own.
