NASA spent billions on the James Webb Space Telescope and now we’re going to launch it really far away. But why do we need to send it so far? And what technologies are on board to support its success? » Recap on the James Webb Space Telescope 🤍🤍youtube.com/watch?v=QO-D0bXcO6g&list=PL6uC-XGZC7X7ACJpjTf83BXAhxCHUkkDh » Subscribe to Seeker! 🤍bit.ly/subscribeseeker » Watch more Elements! 🤍bit.ly/ElementsPlaylist » Visit our shop at 🤍shop.seeker.com Mostly known as the successor of the incredibly popular Hubble Space Telescope, Webb will observe the universe with detectors that target near and mid infrared wavelengths. This means that the instruments on board Webb are specially designed to combat some of the historic challenges astronomers have faced when trying to observe the early universe, like huge dust clouds that block the view of celestial objects, cosmological redshifting, and even interference from other bodies. In fact, there are three things necessary to create the perfect environment for an infrared telescope; a large mirror to collect as much light as possible, extremely cold temperatures, and a clear line of sight to your target. Each detail has been thought out meticulously over the past two decades leading to this point, like orbital selection. 1.5 million kilometers is a bit of a trip to say the least. So why are we putting Webb in such a distant orbit? Well, it’s heading to L2, the second Lagrange point around the Sun and Earth. These five points are stable configurations that allow bodies to orbit each other, but still remain in the same position relative to one another. The key to L2 is centripetal force, which you can imagine as the tension in a rope on a tether ball that keeps it connected to the pole. At L2, the centripetal force required for a small satellite-sized object to move with respect to the Earth is equal to the gravitational pull of the two larger masses. Meaning that this particularly cozy orbit has several benefits to support Webb’s mission. #NASA #JamesWebbSpaceTelescope #science #seeker #space #technology #elements Read More: The largest space telescope in history is about to blow our minds 🤍🤍vox.com/science-and-health/22664709/james-webb-space-telescope-launch-date-december-science-hubble "'The Webb represents the culmination of decades, if not centuries, of astronomy,' says Sara Seager, a planetary scientist and astrophysicist at MIT.

But Webb picks up where its predecessor falls short, says Eric Smith, Webb’s program scientist and chief scientist of NASA’s Astrophysics Division. There’s really no telescope like Webb so far, he says." Elements is more than just a science show.

I remember seeing the first seeker video that you hosted : ) you're still doing a great job!
We all begun from Africa, that is the primary lesson many D-heads yet to learn.
What order coordinates of this space. We want to know so we can kidnap it and hold it for ransom. We are your friendly neighborhood alien race
I urge everyone to use Dr Alaho Olu herbal supplements on YouTube because he cured my HSV 2 and HPV. He cures multiple Fibroids too..
How will we respond when Webb sees that we are not only not alone, but live in a crowded neighborhood? Maybe we could use that as an excuse to stop being so puny minded to each other? Great Job Explaining --- about:invalid#zCSafez
A tiny but highly reflective object 4 times further than the Moon, always far from the sun... Will it be possible to see the JWST with the naked eye? What will be its apparent magnitude?
I hope (but do not expect) it goes well.
But can it run Crysis?
Exactly how powerful is the on-board deathray?
should at least wait ( if you live long enough ) until the piece of junk is launched. 15 billion over budget and 15 years late so far
Will the Webb be visible from Earth?
2 telescopes named after Chelsea's Father.
I think the telescope will be outside earth own magnetic field ..directly exposed to solar winds
I think a lot of things could really change after this!!! I seriously feel like I’m a kid again the night before Christmas and can’t wait to open presents and what presents we are about to get from JWST!!!
the question is : NASA will be honest with us?
kilometers? we use miles here ... and we run the world. You are offensive.
Constructive feedback - You should have had someone else write the part of the script explaining L2 and the orbital mechanics . Centripetal force is imaginary and the explanation given confuses more than it helps. The primary benefit of going to L2 is to be able to have the solar shield block the heat of the Sun, Earth, and moon simultaneously. There are other places that this can be done from, but L2 is ideal for some of the reasons mentioned - the reasoning is unclear as presented here. Also, this needed more emphasis on the new low temperature science that is enabled by this telescope IMO.
Wow, the JAWScope is awesome !
Totally incredible the pictures will be mind boggling
