The James Webb Space Telescope took the first pictures of Mars thanks to its NIRCam camera in the near-infrared range.

This was reported by the European Space Agency (ESA), as reported by Ukrinform.

“The James Webb Space Telescope took the first pictures and spectra of Mars on September 5, 2022,” ESA said. Said.

The telescope photographed the Red Planet operating at the second Lagrange point of the Earth-Sun system from about 1.5 million kilometers from Earth.

Early images of Mars show the region of the planet’s eastern hemisphere in two different wavelengths or colors of infrared light.

It is noted that the image taken at a wavelength of 2.1 microns using the NIRCam camera shows surface details almost as seen from orbit. This image shows Huygens Crater, the “dark spot” of Syrtis Major Planum volcanic rock, and the lighter plain of Hellas.

At the same time, the photo, taken at a wavelength of 4.3 microns, shows thermal radiation – the light emitted by the planet when it loses heat. The brightest area on the planet is where the Sun is overhead, as it is usually the hottest. The brightness decreases towards the less sunny polar regions, and less light is emitted from the colder northern hemisphere, which experiences winter at this time of year.

As Ukrinform reports, in August, the James Webb space telescope took several new photos of the planet Jupiter.
