What a Christmas present for the world. A $10 billion present, that is. It cost as much as the Large Hadron Collider in Switzerland/France.

NASA plans to launch the James Webb Space Telescope into orbit Dec. 18, 2021, to serve as the premier deep space observatory for the next decade.

The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity. The longer wavelengths enable Webb to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.

My word... that thing is huge! You really can't grasp how big the space telescopes are until you see a person next to one.
It will cost about the same of the LHC but I imagine a lot of that is spent ensuring it won't need constant maintenance, the LHC (while vast in size) has people maintaining it constantly. I am really looking forward to seeing what it finds out there.

The sun shield is the size of a tennis court. Yes, it’s big.
It promises to turn what we know about exoplanets on its head. I am especially interested in what we’ll find orbiting Alpha Centauri A and B. A is the bigger star and B orbits it at the same distance that Saturn is from the sun.
A is slightly larger than the sun and B is slightly smaller. That they’re so close may have eliminated the formation of smaller planets but then Jupiter isn’t exactly tiny and four rocky planets developed between it and the sun. So, there’s a chance rocky planets formed between A and B, too.

It costs so much because after the first 10 years they scrapped it all and started over.
Im really interested and seeing what kind of things it finds. Its supposed to blow the the hubble out of the water.
Only thing i wish they had considered is that it inly has a 5 or 10 year lifespan due to it needing propellant to stay in its orbit.

We do live in an age of discovery for space. Not since the glory days have we found out so much so quickly.

Maybe by then one of the billionaire astronauts will have developed a way to reach and refuel it, if only by robotic means. I’d like to know if NASA planned for a possible contingency for refueling it. If they didn’t then that was short-sighted and extremely expensive.

Great stuff. Can’t wait to see what it sees.
Really appreciate the science posts from you two fellers.

Our orbiting telescopes are named Webb and Hubbell?
How unfortunate.

Jimmy Webb Telescope, I wonder if you can see Galveston with that thing?

That’s fricking awesome. Been waiting years to see the composure of atmosphere’s of planets orbiting nearby stars.
