How The James Webb Telescope Takes Photos Of Space

The James Webb Space Telescope is about to revolutionise humanity’s comprehension of the cosmos. On its five-year mission it’ll gather heretofore unimagined insights into the birth of galaxies - and offer a realistic shot at finding life on other planets. Or, some worry, it’ll simply fall apart during its insanely complicated deployment.

[@katlehomakhalemele]

Can someone please explain the 'back in time' part. Trying to understand what that actually means in this context.

[@arildandreassen6402]

The gist of it is that light travels at 299 792 458 m / s, or over the course of a year light has travelled....1 lightyear. So if you look far enough out, you will see events that took place millennia ago, but the light is only now just reaching earth. Proxima Centauri is the closest star, ~4 lightyears away. It will take light 4 years to reach earth. So what you are looking at today really happened 4 years ago. Something like that.

It's not a 5 year mission, it's 10 years! Though humans cannot refuel it, there are plans for robotic refueling. I bet the mission will be longer than a decade.

[@binthenw3148]

The 4 pictures it shows taken by Hubble are absolutely amazing! Especially the one on the bottom left, the amount of stars in that picture is insane. It blows my mind that there are still some people that don't believe in life forms/aliens on other planets, the fact they could see a picture like that and how many stars are in just that one picture and think that there is no other life forms is ignorant lol hopefully with the James Webb telescope we can actually spot sone planets with signs of life or at least ones that have a suitable environment for it. This is so cool! Can't wait to see pictures from it.

Just a minor comment and sugestion. You run a science channel and should use the metric system measurement, not the imperial system. BR from Sweden

[@Steve-Richter]

Why not include a small robot craft that could be remotely controlled and correct deployment problems?

Yeah, submit your ideas - I think they’ll change their plans right away :)

[@killmoreturtles]

As complicated as this is, much of it is answered with Math. What I'm wondering is if there is anything that is more of a " roll of the dice"? I realize they can't do anything about space debris, but is there anything else that they are hoping for a bit of a 50/50 chance? Like maybe the unfolding of the telescope? Or how do they determine that without doing that in space? It feels like, without this thing being done in space itself, it's going to be very unpredictable at too many points; but hopefully that is not right and the Math is all there?
