Keeping an #infrared telescope at very cold operating temperatures isn’t an option, it’s an absolute necessity

JWST operating temperature is less than 50 degrees above absolute zero (−223° C or-370° F) and will be the largest telescope ever placed at that cold temperature (50 Kelvin).
Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the #BigBang, when the first stars and galaxies started to form. JWST will change our view of the cosmos by taking Baby Pictures of #Universe, looking back to big bang.
#JWST is going to be like “Magic spectacles” that allow you to see things that you can’t normally see.
which is the pictures of the infant universe.
