Big Picture Science for Dec. 26, 2022 - Webb Feat

Big Picture Science - Webb Feat

(REPEAT) The James Webb Space Telescope has turned its golden eye on the cosmos. The largest, most sensitive telescope put in space since the Hubble Space Telescope is already producing new photos of far-off galaxies and other cosmic phenomena.

In this episode: astronomers share their reactions to these stunning images, the project scientist on JWST describes how infrared cameras capture phenomena that are invisible to shorter wavelengths, and a plan to investigate the very stardust that created everything, including you and me.

Guests:

• Néstor Espinoza – Assistant astronomer, Space Telescope Science Institute, principal investigator for exoplanet atmospheric physics, James Webb Space Telescope
• Alyssa Pagan – Science Visuals Developer at the Space Telescope Science Institute
• John Mather – Nobel Prize-winning NASA astronomer and Senior Project Scientist for the James Webb Space Telescope
• Alex Filippenko – Professor of Astronomy at the University of California, Berkeley

PHYSORG.com: NASA team obtains the 'unobtainium' for next space observatory

Yesterday I came across a very interesting article on PHYSORG.com regarding the James Webb Space Telescope, and I thought I would share it with the readers of this blog.

This article "NASA team obtains the 'unobtainium' for next space observatory" is about the development of a new composite material and the testing involved to prove that the material could withstand the super-cold temperatures it would encounter when the observatory reached its orbit 1.5-million kilometers (930,000 miles) from Earth.

It's a very good read, and I hope you enjoy it as much as I did ~ Jim Cox
