Why Do We Put Telescopes in Space?


If the purpose of a telescope is to bring far-away things closer to us, then why do we send some of them so far away? The main reason to put a telescope into space is to avoid that perpetual troublemaker: the atmosphere since astronomers haven’t yet figured out how to get rid of it. And it’s a big nuisance. First off, the atmosphere plane gets in the way, what with its clouds and smoke and haze than can block light from distant stars or nearby planets. And even just the air in a clear sky blocks a huge range of the wavelengths of light, pretty much only letting through visible light, and a smattering of infra-red and radio waves. The atmosphere is also- -HEY! Stop that!- …Distracting At day, visible light from the sun bounces off of air molecules, and other small particles and completely overwhelms the light from any other star you might want to look at. At night, the light from the moon and from human sources bounces off the same paricles and outshines the light from most distant and faint stars and galaxies, washing out their images. The atmosphere AlsO MeSSEs ThINGs up. Air is constantly moving, and just like a heat mirage, this turbulence blurs and distorts starlight, which causes stars to twinkle, and telescope images of stars to be blurry We can avoid all of these nuisances by putting telescopes above the atmosphere, in space. Plus, there are other benefits; A space telescope can make observations 24 hours a day, A space telescope can be put far enough away from the earth’s infra-red warmth and then cooled down really cold so that it can take clean infra-red images, and a space telescope is a telescope we freaking put in outer space! Of course, there are some downsides to space telescopes; It’s hard and expensive to get them there, hard and expensive to fix them if they break or you want to upgrade to newer fancier parts, hard and expensive to take people there on tours, but really, How can you argue, with *this* And this And, this And this And this And this And even this And this And, this This too. And this.

  1. We are not talking about this makes an imaginary triangle with his fingers or this a square, we are talking about this a circle, Spongebob.

  2. Hey, do you remember that movie you saw over at The Fine Bros place? The one you said you loved and wanted to see? The Horribly Slow Murderer With The Extremely Inefficient Weapon? They're trying to kickstart fund a full movie version of it now: https://www.kickstarter.com/projects/richardgale/ginosaji-the-horribly-slow-murderer-movie-project
    (It's not likely that Henry will see this comment, but if you, who do see it, feel so inclined, can you try to help me raise awareness of the movie? Maybe send him the link on his facebook or twitter or something? I don't have a facebook or twitter account of my own so, unfortunately, I cannot do it myself… But I really want this movie to be made.)

  3. i always believed those pictures from space were cgi. i know some hav color added to thm so i cant convince myself gas or what looks like gas-images are real.

  4. another problem is that their mirrors are very small… when europe is building a 40m telescop…. I dream of this 40m in space…
    another advantage is that you can take one picture shoot for days…. without the problem of the earth rotation.

  5. Could you make a video about how bubbles in soda (and particles) are affected by temperature?
    Thanks.

    PD. Yes, I liked my own question.

  6. Why not make some videos quickly explaining some equations, when I mean to quickly explain, maybe give what the terms are, explain what overall equation is used for and maybe what is needed to throughly learn the equation. For example newton's gravitational attractive force, maxwell's equations, schrodinger's equation etc. I think it'd be cool to give a quick overview of the maths behind some of major concepts in physics.

    Or maybe not, I don't know, it's your channel XD

  7. Do you have a video explaining volts,amps, and watts? I never really understood those concepts and their difference. If not you should make one I'm sure it would be enlightening.

  8. Why put telescopes in space? So we can spot the reptilian home world of course! HISSSSSSSSS! Join the reptilian brotherhood HISSSSSS!

  9. Rockets do leave earths lower atmosphere, care to show a rocket putting one of the thousands of satellites in so called space? Dont kid yourself you can't fact.

  10. could you do a video commenting on athene's theory of everything? he brings up some interesting perspective's but i think he gets a little lost when talking about relativity and quantum mechanics.

  11. sure, supposedly "NASA" puts telescopes into "orbit" around a "round" planet to takes pictures of "space", sure. gotcha.

  13. Professional astrophotography with CCDs and " normal" telescopes is hard. But if you have the ability to use a telescope in space, it is actually very easy. You just have to point it somewhere and you get a beautiful image, because there are galaxis everywhere. You just have to take a very long exposure.

    Of course, you have to figure out the most efficient way to point the telescope at the spot you want, but the computers can do all the hard stuff.

  14. We can now use interesting techniques using lasers and adaptive optics to correct the lens shape of ground-based telescopes to compensate for that atmospheric distortion so we can do space telescopes from the ground.

  15. first off.. it's SO NICE SEEING YOUR FREAKIN' FACE AT LAST.. and also… all those images you showed us… ARE REAL?? I thought they where "artistic simulations" of how things look with a telescope.. didn't know those spectacular images of distant stuff are REALLY THAT CLEAR!!!!!

  16. Hey, someone please explain me, the images which were shown at 1:42 minute mark, aren't those converted and put under the visible region of the EMR spectrum? I mean, if we evolve and technology advances as such that we're able to travel that far away in space, will we see such things through our narked eye? Do they look like that for real or the infrared & other radiations are converted to the visible region to create the image?
    Please tell me they actually look like that. THE UNIVERSE IS OVERWHELMING!

  17. pls answer this question
    what should a levitating mosquito in a moving car do to stay in the same position relative to the person in the car. move forward or stay in the same position ?
    this is my question which I am exploring the answer for since 3 years
