Astronomers want to measure the heat signature from the early universe. The cosmic inflation red shifts early light from the universe and water vapor absorbs infrared radiation hence they put an infrared telescope in space insuring the cleanliness of the mirrors from water-vapor and dust every step in the making of JWST. There is an armor-coat applied to the top mirror surface to alleviate contamination resting and to protect the mirror from micro-meteor impacts.
They cool the beryllium(hexagonal crystal structure and a good neutron reflector) with gold (less chemically reactive than silver) plated mirrors. Keeping the mirrors cold increases sensitivity to IR radiation. That's good because of less exposure time . Pictures of far away galaxies could be made in days instead of months.
The extra layers of sun shield are over-engineered so the mirrors get cooled more than necessary (half a kelvin difference matters here) just in case the shield doesn't perform as well as expected.
However, inventor anon claims these mirrors somehow can detect neutrinos. Is it electron-neutrinos you are referring to?
The radio observatory in Ohio also was able to detect a powerful neutrino beam, but I find it difficult to visualize how neutrino-electron interactions work.
Is the JWST infrared observatory just an infrared telescope as advertised? Is the recent delay to tension the sunshield sus or not sus? Were astronomers conned into bankrolling a defense intelligence neutrino observatory?
Why is beryllium a good neutron reflector and why is its crystal structure unique? How does beryllium connect to skyrmions and magnetic moments?
Inventor anon, can you please give me a hint. A simple sketch of a feynman diagram could help a student correct mistakes in understanding.
news btw
It seems like there was a hiccup.
Engineers activating the James Webb Space Telescope decided Sunday to hold off tightening the observatory's critical sunshade to allow more time to check out the performance of its power systems and overall behavior now that several major deployments are complete.
