James Webb Space Telescope helped us see the deepest ever image of the Universe

When it comes to making observations in the #infrared spectrum, special care must be taken to ensure that the #jameswebbspacetelescope remains cold enough that it's own radiations don't mess with the readings. Here comes #aluminium to the rescue! The #JWST has a five-layered #sunshield whose membranes are specially coated with aluminium on both sides to reflect the sun’s heat back into space.
