The James Webb Space Telescope is the successor to the Hubble's throne. In order to pick up extremely faint infra-red signals from extremely distant stars and galaxies, the JWST has to be extremely cold. Any noise from the IR radiation of the Sun or Earth would make it impossible to see as far into the past as scientists want to.

Thus, the JWST has to be a million miles from the earth, protected by a six-layer heat shield as big as a tennis court. This will allow the Webb Telescope to peer into the deepest reaches of space, through clouds of dust into stellar nurseries and back in time 13.4 billion years.

Not only will we get the most detailed views of our universe ever, but the JWST will provide insights into how solar systems, galaxies, stars and even the Universe were formed.

  • do a video about voyager 1

  • The images, think of the images.

  • I live in LaGrange

  • I feel like this is one of the nerdiest videos Hank has ever done. If anyone ever asks me to point them towards a nerdy video, I'd send them this.

  • @MrChaos424242 The atmosphere of Earth really impairs a telescope's ability to see into space even if you are looking during the night I believe.

  • @MrChaos424242 because you cant see much more things into space because its closer to them if you put a telescope on earth you could see the space but not much of it we do have telescopes on earth their just not that good

  • I think we've decreased the dislikes for this video enough. It's time to increase the likes.

  • @MrChaos424242 The atmosphere blocks a lot of the type of light that the JWTS is looking for. Pictures are a lot better when taken from space.

  • This is probably a silly question, but why do we need to spend so much money putting a telescope in space when it seems to me we could put that telescope here on earth where we could fix it easily?

  • Hank is really pale in this video. :P
