NASA's James Webb Space Telescope
The agency's successor to the famous Hubble telescope, launched on Dec. 25, 2021 on a mission to study the earliest stars and peer back farther into the universe's past than ever before.
Webb Is Currently At Its
Observing spot, Lagrange point 2 (L2), nearly 1 million miles (1.6 million km). It is the largest and most powerful space telescope ever launched.
In A New Update
NASA revealed that the James Webb Space Telescope is almost fully-cooled.
Webb Observes In Infrared Light
Which we know best as heat. To make sure its observations aren't contaminated by any heat from the scope itself, Webb has to be extremely cold.
The James Webb Space Telescope's
Mid-Infrared Instrument (MIRI) finally reached the super-cold temperature needed to operate as designed.
Because The Instrument Targets
Infrared light, which manifests as heat, the instrument must remain under 7 degrees Kelvin, which is equivalent to minus 447 degrees Fahrenheit
