How NASA's James Webb Space Telescope Will Answer Astronomy's Biggest Questions (Synopsis)

By esiegel on March 1, 2017.

"The [James Webb] telescope is basically designed to answer the big questions in astronomy, the questions Hubble can't answer." -Amber Straughn

Have you ever asked the biggest questions in the Universe? Questions like how the Universe came to be the way it is today? How the first stars and galaxies -- the first light -- came to be in the Universe? Whether Earth-sized worlds around red dwarf stars have atmospheres, possibly with signatures of life? And what the Universe was like when the first stars were just forming? The James Webb Space Telescope was designed to answer these questions and more.

Scheduled for launch in October of next year, and right on track, James Webb is poised to revolutionize astronomy with as big a step forward from Hubble as Hubble was from ground-based telescopes. And best of all, scientist Amber Straughn will be giving a free, live-streamed public lecture on it that I’ll be live-blogging today, at 7 PM ET / 4 PM PT.

Watch from anywhere in the world, or catch it at any point afterwards. It’s the future of astronomy, and it’s about to begin!

That was enjoyable. Dr. Straughn was clear and engaged throughout, and her review of the project included the latest developments, the invitation for requests for time after the JWST goes live. I think they’re due for submission the day after tomorrow.

It’s been a long time coming. Let us hope for a flawless deployment.

I have been waiting so eagerly for this launch event, complete with all of the magnificent things it would reveal. I was expecting this would be an unbelievable shift in my view of the universe.

Unfortunately I will not be here. I am laying in my new temporary hospital bed here at home, as cancer eats away at my body, with probably only a week or two to live.

Ethan, your explanations of the workings of the universe have been absolutely delightful. I cannot say how much this website has meant to me. Really!

I also want to thank you for the kind sentiments you expressed to me in the past when I was enduring totally unnecessary legal troubles. It was genuinely an uplift to receive your understanding comments.
