James Webb Space Telescope: NASA’s giant eye in space explained

It’s covered in gold and can see light that has travelled for 13 billion years. But NASA’s James Webb Space Telescope has also had a troubled history. Here’s why this powerful space observatory is a game changer. Subscribe to CNET: Like us on Facebook: Follow us on Twitter: Follow us on Instagram: Follow us on…

    It still blows me away the kind of images we get from Hubble and that was launched back in the ’90s! So excited to see what the JWST delivers.

      They won’t be as spectacular, webb will focus on infrared not visible

      @` Not necessarily… Look at the side by side example at around 3:55 There’s much more detail & clarity.

      @Adam Strachn Yeah I guess my comment wasn’t terribly thought out, though at least the stuff we know from Hubble won’t look quite the same, like nebulae will probably look a lot less cool and everything will of course have to be artificially colored

    I will watch the launch from Paramaribo, Suriname neighbouring French Guyana

    I am so excited if this works and it’s genuinely gonna hurt if it doesn’t.

    The first pictures will be the most exciting pictures since the pictures of Pluto.

    But why can’t astronaut’s fly there and fix it if it needed fixing? It’s not like it’s far out like Mars, and they want to go to there

    You need to stop referencing Bezos as if he isn’t an enemy of the people. You can f off with all that non-starter garbage.

      NO KIDDING. Musk is just as bad even if he’s adding a helpful element to economic pressures. They’re both pretty terrible people. Why would she think that was clever? She certainly lives in a gaudy bubble ignorance

    Never.. EVER joke about us wanting Bezos or any of his billionaire suborbital toys ever again. I threw up in my mouth

  10. Good Citizen

    December 21, 2021 at 8:32 pm

    You actually think we like Bezos? What is wrong with you? We don’t even like Musk. Unless you’re noticing one of their mindless online robots or an impressionable child who doesn’t understand that billionaires are not our pals.

    How is the exposed open mirror surface, once in space, protected against micrometeorites?

    Been waiting decades for this thing. Really hope that the launch goes well.

    It’ll probably take a couple of months for the show to start. I’m thinking mid June.

    This woman should never be allowed on your channel again (The host). To even bring up such a negative thing about James Webb (The man). About something in her own words was found not to be true. (Keep this woman away from the lunch site). to even bring that up this close to launch as hard as everyone has prepared for this is a disgrace. 🚀 Christmas Eve

      “To even bring up such a negative thing about James Webb (The man)”
      I cannot stand her dumb puns and jokes, either. But, YOU sound like a PRO-CENSORSHIP nut who won’t even allow her to QUESTION NASA.
      Ok… she brought it up, AS IS HER FREE SPEECH RIGHT TO DO, NASA investigated: found no evidence James Webb fired people for their personal sexual freedom. Just stop with the self-righteous over-reacting grandstanding.

    This is going to be cool, new technology means better imaging, new discoveries of other solar systems, other life potentially. I’m excited to see what they capture.

    Good luck JWST team! After launching JWST in deep space and nearby other stars and its planets in our Milkyway Galaxy, eagerly waiting to see some flying objects (aliens in secondary stage) in the sky as well as aliens in primary stage in our solar system also

    Will we be able to get colored images?

    • NoYourself

      December 22, 2021 at 2:54 pm

      I believe the images will have to be artificially coloured because infra red light is not visible to the human eye

    I’m no science geek, but I myself am very interested to see what we discover!🤔🤓😲

    I think a tesla would be more technologically advanced than this thing and it didn’t take 25+ years and 10 billion dollars to build and perfect the first tesla. But that’s government for you.

    I hope it’ll see the moment when God spoke the universe into existence. Won’t that beat all?

    should be assembled at ISS and hen launched

    If we look one way do we see the stars being born soon after the big bang
    And the galaxies hurtling away from us will we see what was before the big bang
    Mindblowing
