How to Supersize a Telescope | Compilation

Telescopes can get pretty big, incredibly big actually. Unbelievably big. So here's a compilation about how we managed to get them that size and how that size helps us to see.

PBS Space-time also recently did a video about the exoplanet telescope. Worth a look

[@davidhand9721]

Thumbs up and super agree.

[@RedHair651]

I visited the Leviathan. Birr isn't very big and there isn't a lot you can do "to" the telescope (you can't get up on it, demonstrations of its motion only happen sometimes, and there's only so many things to read about it on the signs). HOWEVER, once you're done gawking at it, there is a lot to see on the castle grounds: old trees, nice gardens, wildflower,... and an actual radio-telescope that is part of a big European array of radio-telescopes.

Completed in November 1963, the Arecibo Telescope was the world's largest single-aperture telescope for 53 years. (The Chinese made a bigger one in 2016.) The dish was situated inside a natural karst sinkhole negating the destruction of the surrounding area by heavy earth-moving equipment. Shade-tolerant plants were put in around it to maintain the ecostructure. The receptor was the ball you see, but all the struts and wires you see were a gantry that could move the ball anywhere above the dish to receive signals from anywhere and direct them to the disc. It was funded by NSF and NASA but they transferred it to the Univ. of Florida in 2011. More funding cuts followed. Itwas damaged by Hurricane Maria in 2017 and was affected by earthquakes in 2019 and 2020. Inexcusably it was not repaired and several of the major suspension cables let go, one in August and another in November of 2020. There was a rush to try to get funding but no govt or scientific agency was willing to put up the money and it finally collapsed at 7:55 am on December1st, 2020 with the antenna falling into the dish.

Nope. History of the universe is best

At 2:35, the JWST mirrors are not aluminum on glass, but gold on beryllium.

[@Darkmattermonkey77]

Imagine if they turned the crater in Arizona into a radio telescope.

[@sicfxmusic]

Crater? The video is talking about literally turning the sun into giant lens!!

[@davidkelley5382]

I would like to see that done on the far side of the moon. That way the interference from all the sources would be blocked. Like a JWST for radio astronomy.

[@c1osmo]

Love this compilation, revisting these earlier videos with current understanding can re-enforce our knowledge as well see where we had misconceptions. Totally had an "of course you wally" moment when I saw the distances for Gravitational Lensing specific objects. Just overcame a lot of my scepticism to the theory - though sheesh the engineering is unimaginable as of now. Cheers and thanks to you all.

[@amitoj]

Leave something to see in arizona please

[@domsau2]

2:48 JWST: not Al, but Au!

[@SecretRaginMan]

And on beryllium, not glass.

That was really good, Yall are grate

Would have been great to see the sketches and modern day images of the galaxies

[@TragoudistrosMPH]

I long for the day when our Solar System is a telescope!!! Imagine the earth and moon combined, or Earth and Mars!

[@nickromo8195]

There are scientists trying to figure out how to send out probes that would use the Sun as a gravitational lens that would allow us extremely detailed images of very very far away objects unlike anything we could procure from Earth's surface

[@SnarkNSass]

Wow Golly 😎

[@ddh3098]

Omg thanks for the share and stay classy

[@Bf2142HowTo]

LETS GO

[@OverlordZephyros]

Just here to say that they aren't gonna restore the Arecibo radio telescope in Puerto Rico... Apparently doing science and expanding human knowledge is too costly to care 😒😒😒 Hope someone with a science background or connection see this and do something about it

[@nebulan]

On the other hand it paid itself off. It ran for a long time and we learned a lot! I imagine those who operated it will look into redirecting their budget to a different telescope or funding a new one. Maybe scishow can cover their future plans!

[@Sniperboy5551]

It’s better to just build a new, better one. It sucks what happened to it, but repairing it would probably cost more than building a new one.

Has anybody ever tried freezing the mercury so you can point it wherever you want? Only problem i see is idk what kind of surface disturbances the whole freezing process would make, like crystals and it contracting, maybe if you freeze it very fast or something

[@RPSchonherr]

A Lagrange telescope is possible. Place radio telescopes at several Lagrange points and you get a lens as big as the Earth's orbit.

[@theenchiladakid1866]

Are there any new photos of these galleries

[@Late4dinner1]

I firmly believe that if we as humans actually spend the time and energy required to actually travel to another galaxy we can and we could likely thrive as a space faring civilization

[@neddyladdy]

Please, what does supersize mean when. I think I can understand it used as a noun, but I have no idea what is means as a verb.

[@dutchik5107]

I think it is something an American gas station or something has as a massive drink size. I think in this context. The "verb" "to supersize something" means "making something ridiculously big"

[@neddyladdy]

@@dutchik5107 I thank you for the reply dutchik.

interesting

[@kuntamdc]

Can the Jwst image a rover on Mars ? Or look at subjects closer to us for that matter

[@ColCurtis]

Not enough resolution at that distance to see the rover, look at the jwst jupiter pics for an idea of its resolution. Jwst is built to observe very far away large objects in infrared.

Can we use gravitational slingshots for interstellar time travel. A warp highway.

[@ColCurtis]

Nope

[@osmosisjones4912]

@@ColCurtis not now say would it ever be possible

[@nankinink]

they don't add that much energy into the object, so for human-lifetime travels? no. If more than 1000 years to reach interstellar travel is ok? Sure, all interplanetary probes uses it to go beyond earth orbit.

[@osmosisjones4912]

@@nankinink if a warp drive would require more energy then mass of Jupiter then . Instead of fighting it on a space ship . They s Would be entire space stations . Maybe chains of them. . But that's warp past light speed.. warp to light speed might be more possible. And with rotation of the Galaxy.. maybe can travel as far back in time as time is moving forward. Taking years out of light years

[@Aragorn7884]

... that's what she said 🤔😏

[@tobyihli9470]

The expression that gravity “warps” space is nonsensical. “Space,” in the literal form, is the void which exists in every direction. Gravity can only warp things which are contained therein. Somehow the use of the word, “space,” has changed, without any mark or connotation regarding it. “Space,” has historically referred to the void, not the universe which occupies it. As there is no such tangible thing as “time,” and “space” refers to a void, the words, “space time,” has no meaning whatsoever. People are constantly trying to use the words “space time” in sentence, although from the context of the words I can’t tell why. I suppose that they feel it makes them look smart. Maybe they believe that they can somehow “speak, it into existence.” It’s sad, really. I think it’s a sign of insecurity, myself.
