The Hubble Space Telescope was launched in Earth orbit in 1990 over 25 years ago. The Spitzer Space Telescope, the Infrared brothers & # 39; Hubble, celebrated its 15th anniversary in space. Multiple Observatories of the X-ray, including the Observatory X-ray Chandra, XMM-Newton, and Array telescope Nuclear Spektroskopiku (or NUSTAR) are also seeing the sky from their perches in space, high above land above the Earth. In the next decade, NASA plans to launch the James Webb Space Telescope, the next-generation Hubble and Spitzer, will sleep x-Sun.
Placing & # 39; telescope in space has its limitations. For starters, it can not be too large because it fits inside the rocket launch. Our ability to repair is also limited to (knock on wood) something goes wrong. And finally, to state the obvious, it is quite expensive. So why do we even?
The main reason to put the telescopes in space is to reverse the Earth's atmosphere so that we can look over the planets, stars and galaxies that are studying. Our atmosphere acts like a protective blanket to give just a little light through & # 39; blocking & # 39; others. Often it is a good thing. No level & # 39; & # 39 SPF can; protect us if we have been bombarded by X-rays & # 39; or high energy gamma rays whenever they went out. But that protection means that we are unable black when it comes to gathering & # 39; those forms of & # 39; light to the land-based studies. We can not ask the atmosphere to make any special exceptions to light that we hope to reach our telescopes.
