## 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. Thank you so much for watching, This video was supported by the James Webb space telescope project at the space telescope science institute where they put telescopes into space so you don’t have to deal with stuff like clouds, and rain. Thanks again for watching, and thank you again to the James Webb space telescope project for supporting this video

We are not talking about this

makes an imaginary triangle with his fingersor thisa square, we are talking about thisa circle, Spongebob.waste. of. money.

0:56 the atmosphere is Alsace bzzbzbzrtzzsrwrzz

and this too

what about meteoroids in outer space?

You have a face.. !! 🙂 Even without one you are brilliant! 🙂

Looks like ASAP SCIENCE

Went to nasa in Greenbelt md. We saw the clean room where they are making the James Webb telescope

No photo of Pluto? How dare you good sir!

(Un)subscribed.

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.)

I have a question: What shape is the universe?

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.

Hubble, I blow you a kiss!

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.

1:45. is this actually a real picture?

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

Thanks.

PD. Yes, I liked my own question.

1:40 EPIC

HISSSSSSSSSS

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

why did you and this and this and this all the time?

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.

Why don't you post anymore😫

Put telescopes in California. We don't get any clouds or rain

HE CUT HIS HAIR AND GREW A BEARD! WHAAAAT?

korea

i love the end

0:56 the atmosphere is also …. messes things up

And this

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

what about this>>>*

it a star =3

is it true we dont have a picture of our own galaxy??

That is very well explained. And cool graphic art too!

What about Lucky Telescopes?

Wow Henry that was some nifty space porn at the end there wow

AND this

the last space picture is the one that is on my desktop background

Scientist have solved the atmosphere problem short of , aka adaptive optics .

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.

Superb videos you guys…Big applaud for these engaging videos..!!!…Got a lot to learn from you..Thanks

Dear minute physics can you please make minute astronomy please…

SCAMAZ

and… deez nuts

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.

Plot twist: he's also the guy that does xkcd.

0:35 did he told stop or a badword?

No, just smog LOL

Not so hard or expensive with Star tram.

can you please tell me the pen you used at 0:48 exactly ???? i would love to buy that !

that last 'and this' looks like something out of skyrim xP

Another one. Another one. Another one. Another one.

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

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.

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.

i want to deep throat where your sissy voice comes from

is the image at 1:47 a black hole?

Stroke: 0:54

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!!!!!

thank you a lot for this amazing video

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!

Nooo waaay, that the pic at 1:22 is real… noo fkn way

I'm psyched for JW Space Telescope. We will finally be able to detect possible signatures of life on exoplanets.

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

all i saw at the end was a bunch of potential wallpapers

galaxy pics are my aesthetic tbh so thanks smart space people for letting my tumblr look nice

those pictures are so beautiful they almost made me cry 🙂

1:11 That accidental drawing of a Lunar Eclipse is extremely inaccurate.

And this and this,this too

do short wavelengths (blue) mean that they're coming closer or is it long (red)

Can anybody explain the image @ 1:46 ?

GREAT NOW I'M HAVING AN EXISTENTIAL CRISIS AHAHAHA

We should put a telescope on the Moon

1,000.

Hubble is love, Hubble is life!

Anyone else accidentally read "why dont we put telescopes in space"? no?

Xd the end though

R.I.P headphone users @0:56

Thank you this helped a lot

Press the 5 key… and then press it again xD

so beautiful
