Once it's launched, the James Webb Space Telescope will look way back in time to right after the universe formed. But what cutting-edge tech allows Webb to peer back so far, and how exactly does it work? » Subscribe to Seeker! 🤍bit.ly/subscribeseeker (then hit the little 🔔 icon and select "all.") » Watch more Elements! 🤍bit.ly/ElementsPlaylist » Visit our shop at 🤍shop.seeker.com When you look up at the night sky, you’re only seeing a tiny fraction of the estimated septillion stars out there in the universe…and honestly it’s not your fault…even astronomers have a hard time. But now the James Webb Space Telescope may just make things a lot easier and push the very limits of infrared light observation to travel back over 13 billion years ago for a glimpse of our universe’s first light. #space #jameswebb #jameswebbtelescope #jameswebbspacetelescope #Seeker #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 launch, which will propel the Webb to nearly a million miles away, is now scheduled for December 18, 2021. When it fully deploys in space, the Webb will usher in a new age of astronomy, scientists say, and show humanity things it has never seen before. Webb vs. Hubble Telescope 🤍🤍jwst.nasa.gov/content/about/comparisonWebbVsHubble.html This is the other reason that Webb is not a replacement for Hubble; its capabilities are not identical. Webb will primarily look at the Universe in the infrared, while Hubble studies it primarily at optical and ultraviolet wavelengths (though it has some infrared capability). NASA’s Webb Telescope Will Look Back in Time, Use Quasars to Unlock the Secrets of the Early Universe 🤍scitechdaily.com/nasas-webb-telescope-will-look-back-in-time-use-quasars-to-unlock-the-secrets-of-the-early-universe/ The quasars the team will study are not only among the most distant in the universe, but also among the brightest. These quasars typically have the highest black hole masses, and they also have the highest accretion rates — the rates at which material falls into the black holes. Elements is more than just a science show.

Gonna be a nervous wreck christmas eve. I hope JWST launches without any issues, so excited to glimpse further into the past. Still love you hubble but cmon.

How does Euclid compare to the Webb?

Let's hope once launched it will go without a hitch.

I don't think of it as looking back in time, instead its like a really bad time delay

NASA does have a live video feed posted on YouTube so if Seeker doesn't I'll check out NASA's feed and their website too.

Seeker will you post the images that James Webb will be taking? If not can you direct us to where we can? NASA?

What's cooler, living biology emits infrared radiation that can pass beyond Earths atmosphere. If an alien planet has a similar atmosphere, hypothetically we can detect living creatures.

If JWST can see 13B years in time, does it mean the observable universe is nearly same as the actual universe?!

As with all such instruments, there is a tendency to concentrate on the science and skip over the engineering. This has been particularly true of videos that covered the LHC. I would like to know a lot more about the details of the detectors and the electronics.
What sort of detectors are used, what exactly is a slit-less detector? Are they cooled? How are they powered? How are the signals processed? This video at least shows the mechanics of the instruments. But often the how's are as important as the why's.
