James Webb Space Telescope took first pictures of Mars

The James Webb Space Telescope has captured its first images of Mars. recently released data come from the telescope’s infrared instrumentsThey also provide scientists with information about the planet’s surface and atmospheric composition.

The European Space Agency announced that James Webb captured Mars for the first time on September 5 thanks to the Infrared Camera and Spectrograph. this first sight Consists of two images taken at two wavelengths and shows the eastern hemisphere of the planet bathed in the Sun.

Telescope Spectroscopic data collected on Martian atmosphere Using near-infrared spectrographs, the instrument also reveals some of the molecules that make up Mars’ thin atmosphere, including carbon dioxide, water and carbon monoxide.

WR140 is a variable star.

In the future, Webb will use spectroscopic data to Find regional differences around the planet And look for species in the atmosphere (including methane and hydrogen chloride).

Thanks to this information, James Webb’s ability to accurately characterize the atmospheric composition of different planets.

These are the first pictures taken by the Near-Infrared Camera (NIRCam), show a region of the eastern hemisphere of the planet in two different wavelengths.

It appears as a place of light.

The Red Planet is one of the brightest objects in the night sky in terms of visible light.It therefore presents special challenges for the observatory, which was built to detect extremely faint light from the most distant galaxies in the universe.

The telescope’s instruments are so sensitive that, without specialized observation techniques, the bright infrared light coming from Mars is blinding, causing a phenomenon called ‘detector saturation’.

To rectify the situation, Astronomers Adjust Mars’ Extreme Brightness Using very short exposures, measuring only a portion of the light reaching the detectors, and applying specialized data analysis techniques.
