Neil deGrasse Tyson Explains Space Telescopes

How did the first space telescope arrive in orbit? Neil deGrasse Tyson and comic co-host Chuck Nice explore the literal rise of telescopes from Earth into space. You’ll find out what telescopes were called before they were called telescopes. Discover more about early refractive telescopes and their issues with chromatic aberration. Then, you’ll hear how Sir Isaac Newton came in and changed the telescope industry for good by inventing the reflecting telescope. Neil explains why Earth’s atmosphere prevents you from seeing clear images from the ground. Take a trip through the space telescope hall of fame as we discuss the Hubble Space Telescope, the Spitzer Space Telescope, the Chandra X-ray Observatory, the Compton Gamma Ray Observatory, and the soon to be launched James Webb Space Telescope. Lastly, you’ll learn why Hubble might be the most successful science instrument of all time. All that, plus, Neil shares why the different bands of light act as different dialects for the language of the universe.

[@AmanRaiAgrawal]

5:55 yes, an equivalent of atmosphere distortion would be Gravity, as it can bend light and distort image.

[@Dampfaeus]

I was wondering why it was not mentioned. It must've sprung into Neil's mind the moment the question was asked. I am guessing the second he took to say "NO." was the time it took to consider to open up the topic on gravitational distortions. But it's a whole other beast and would've probably let way off topic for too long.

[@PapiBocaChula]

Another person that knew Mr. Neil was WRONG. yes Validation. But they to high and mighty to ever admit being wrong.

[@christophercooper4078]

A little different, our atmosphere blurs our images making it more difficult to observe distant smaller objects like individual stars, gravitational lensing distorts the image but doesn't prevent us from distinguishing it using computer software. Hubble currently uses gravitation lensing to get better shots of distant objects.

[@pavansupul]

The atmosphere distorts the images and data in which we would like to study about cosmos. That makes atmosphere an unwanted inconvenience. However, if our objective is to study the atmosphere, these distortions maybe considered valuable. I think, Neil said "NO", because the distortions occurring in space due to whatever reason is a whole separate subject for study rather than a nuisance in general.

[@jonathanmoody8757]

It's not really the same type of distortion. It's part of the signal, not noise like the atmosphere. There is something similar to atmospheric distortion though, and that is the milky way dust clouds. These block visible light, so redshifts are not able to be measured in this plane.

What is the equivelant of atmosphere distorsion of the image in space ? NDT: No. Me: Gravitational Lensing , yes we can mostly calculated it but it does distorts the light coming to us.

[@takeuchi5760]

Couldn't gravity of some really big star or a black hole bend light rays coming from other stars? hence more or less "equivalent of atmosphere" as Chuck put it

[@bobdavi9455]

einstein predicted light passing the sun would bend 1 3/4 degrees of arc, so a british scientist went to south america to film an eclipse of the sun and proved light bent passing the sun by 1 3/4 degrees of arc.

[@takeuchi5760]

@@bobdavi9455 does that mean the position a star behind the sun or some celestial object bent like the sun's position is bent by the horizon on sunset ans sunrise?

[@Theoq99]

Neil what do you mean No twice, isn't gravity bending light exactly what chuck was alluding to by equivalent distortion in the wider universe? We have used the gravity from whole galaxies to magnify the light from other earlier galaxies behind them, but I don't understand how they reconstruct an image when the light is smeared into a ring around the front galaxy.

[@Ketraar]

Well gravity bending light is not really the equivalent of interference though, in fact in some cases it may serve to enhance our vision as it shows things "behind" objects that would otherwise not be seen.

[@awesomedavid2012]

I thought of that too. In theory gravity, could distort light similarly to that effect if there were strange enough gravitational waves

[@doktordzwonek9306]

@The Truth of the Matter You are not right. Light always travels in a straight line, it doesn't curve. Space-time fabric does, but that doesn't mean light does. Light may be traveling in a straight line through curved space-time fabric, yes. It's not matter of interference. I mean there might be obviously some interference going on, but that's not the reason we can see light hidden behind objects. Interference is simply said an interaction between light waves which is not a reason why light "bends". Interference can produce a light wave, but light wave always goes in a straight line, so you can't "bend" it.

[@Ketraar]

@The Truth of the Matter In the context of the video interference is means things that impact light resulting in worse images, like clouds, different air temperatures, which make collecting light difficult, hence bad for low res objects. Where in space there is no such impact, in the sense that you will always get the light that reaches (near) earth in the same quality. Obviously you wont see stuff behind gas clouds, but then one could argue Planets are interference and then also light itself. So no there is nothing akin to cloud interference in space. Gravitational lensing, as explained above is the effect observed where space-time is bent by gravity in a way that makes lite "bend", its like a astronomic lens, hence the name.

[@doktordzwonek9306]

@The Truth of the Matter what do you mean? Any refraction changes direction of light wave propagation but it stays straight. Same thing when you take a turn and fall out of a car - you wont have a curved trajectory, you will go in straight Line thats basic physics. Gravitational lensing is not a refraction. And any refraction is (if Im not wrong) Just a very complex interference.

[@LuisBurke]

Food for thought. As amazing and mind-blowing as the James Webb telescope launching experience will be for sure.

Can the new telescope see orbiting planets in other stars?? Like directly?

[@JasonWW2000]

The problem there is planets do not produce light. They are dark rocks, etc... Light reflecting off their surface is too weak to see. So the only way we can kind of see them directly is when their orbit passes in front of their star. Then we see their shadow. If we are lucky, we can analyze the light around the edge of the planet to see the composition of it's atmosphere.

I like your comparison to heat waves on a Highway. I’m an amateur astronomy, and I love doing public outreach. Here’s another idea, to explain atmospheric fluctuations. I tell folks that we live at the bottom of an ocean of air. I ask if they’ve ever gone to a swimming pool, and looked up from underwater. Nothing above the water is clear. It’s all jumbled and out of focus because the water has waves, splashes, and swirls etc. It’s the same with the ocean of air above us. It has winds, waves, currents, and swirls which jumble up the light coming through and prevent us from seeing clearly.

[@jonathanaragones6888]

Wow well explained. Thanks Dr. Neil. Just a question to ask. Light can be described as the definer to define which placed ouside the time but located inside the space. Will the one who describe the Light be outside the space but it is actually inside the time? Can we place the Space outside the Time to descride what actually is in the Space? Possible through the use of Light.

[@Sinnbad21]

Neil your reason for why it’s better to drive with low beams in fog versus using high beams is wrong. It has nothing to do with the color of the headlights. It has to do with the angle of the lights. Low beams point towards the ground which means they aren’t pointing directly into the fog in front of you. High beams point directly at the fog in front of you and less towards the ground. Fog is made of reflective water droplets. When you shine your high beams at those water droplets in front of you they reflect the light back toward your eyes making it harder to see

Quick question relating to viewing distant solar systems(relevant to telescopes I guess as the goal is the same, to collect info from far off places.) But would it be possible to send micro craft to our closest stars? Say send out 1000 of them, 100 to each star system, to view a different part of it of each system? Would it be easier to get such a small craft up to the required speeds, and start collecting information that way? I guess I'm thinking, small 1/2kg craft. But I guess considerations there, is obviously firstly, getting such a craft up to sufficient speed to get there is a reasonable amount of time, ie so scientists that launched the craft can receive info back, but I guess that doesn't preclude it's usefulness for future generations. And secondly I guess another concern is could you get enough instruments into such a craft to make the journey useful. Anyway just a thought!

Oh ho, you got me. I wasn't expecting a commercial.
