The James Webb Space Telescope He continues to calibrate his instruments before setting off to explore space in search of the so-called The first light of the universeThis flash was emitted about 13.7 billion years ago, just 100 million years after the Big Bang, in a region of the universe that has hitherto remained unexplored.

For those who can’t wait to see the images that the space telescope will send back to Earth, NASA has released a short video showing the sharpness of the images the device has called. Mary (mid infrared instrumentIt contains a camera and a spectrophotometer capable of capturing wavelengths longer than our eyes can see. Video lets you compare a photo taken with a file Spitzer Space Telescope And one from the James Webb Space Telescope Large Magellanic Clouda dwarf galaxy, a satellite of the Milky Way.

The comparison is surprising and can be seen in his tweet Telescope’s official account With the following caption: “Computer improvement! Compare the same target seen by Spitzer and in Webb calibration images. Spitzer, NASA’s first large infrared observatory, has paved the way for Webb’s larger primary mirror and its improved detectors to see the infrared sky more closely. clarity.”

Computer, promotion! Compare the same target — seen by Spitzer and in Webb’s calibration images. Spitzer, NASA’s first large infrared observatory, led the way for a larger Webb main mirror and improved detectors to see the infrared sky with greater clarity: https://t.co/dIqEpp8hVi pic.twitter.com/g941Ug2rJ8

The James Webb Observatory is considered a successor to Hubble Space Telescopes s Spitzer. Although the probe was launched on December 25, 2021, The project It started over 20 years ago and includes NASA, the European Space Agency (ESA), and the Canadian Space Agency. The James Webb probe will begin observing space in the summer of 2022. It is estimated that the mission of this advanced device will last from five to ten years.
