Both cameras are far more sensitive than the standard cameras used on Earth. NIRCam and MIRI can detect the tiniest amounts of heat from billions of light-years away. If you had Webb’s NIRCam as your eyes, you could see the heat from a bumblebee on the Moon. That’s how sensitive it is.

The James Webb Space Telescope has made yet another stunning discovery to round out three years of space exploration. This time, the most powerful telescope ever launched into space uncovered a cluster of forming stars within the "toe beans" of the Cat's Paw Nebula.
