The Biggest Space Telescope. James Webb Space Telescope Worth $10 Billion.

We’re on the verge of seeing over 13.5 billion years back in time to see things scientists, astronomers, and human beings have only ever dreamed of seeing.
NASA’s James Webb Space Telescope is a true technological marvel. The largest and most powerful space telescope ever built, Webb will be able to gather light that has been traveling for 13.5 billion years, almost since the beginning of the universe. In effect, Webb is a time machine, allowing us to peer at the first galaxies to form after the Big Bang. Because it gathers infrared light, it will see right through the giant clouds of dust that block the view of most other telescopes. Webb will be 100 times more powerful than the Hubble Space Telescope. Webb will be powerful enough to search for water vapor in the atmospheres of planets orbiting other stars. It will open a new window on these exoplanets, observing them in wavelengths of light at which they have never been seen before and helping us gain new insights about their nature. Webb will help us understand how galaxies evolve over billions of years into grand spirals, like our own Milky Way, search for signs of habitability on distant planets, and penetrate into the hearts of dust-shrouded stellar nurseries. The observatory is expected to launch in 2021.

It's pronounced "Exo-Planets" not Exoplanits. I don't mind the robo-voice, but that really stood out. The video got it right once, but wrong several times.

Robot voice said "ex opp lanets" for exoplanets.

Thanks for the video. Can the JWST be aimed toward objects located vertically on the plane of earth's orbit?

Can wait to see the first images from this telescope.

How many times did he say 'size of a tennis court?'

I wish there was a video documenting the advancements jwt will make regarding search for et.

The JWST will change how we view not only the universe but our place in it - it will give us a better understanding of what is around us and help us understand not just what is orbiting nearby stars but at what point they are in their age and composition not ONLY how far but whats near as well.

Another robot voice video. Not worth listening to.
