See the first pictures of Mars taken by James Webb

The NASA Today, the European Space Agency (ESA) released the first (19) images of Mars captured by James Webb Space Telescope.

The unpublished records, made on September 5, depict an area of ​​the eastern hemisphere of red plant.

According to the US space agency, this is a “unique perspective” of Mars, complementing previously collected images and information.

This was possible due to the privileged location of James Webb, which can “see” the side of the planet illuminated by the sun. See the pictures with some notes:

In the upper right corner of the image above, you can see some details of a bumpy region of Mars. On the left, a simulation of the topography of the planet is highlighted. It is possible to see:

  • hole rings Higginswhich has a diameter of about 450 km;
  • pelvis Hellaslighter in color, is a large antique crater of antiquity asteroid;
  • Sirtes Major, a dark “spot” on the planet’s surface, consists of basaltic volcanic rocks that lack the red dust “cover” of the rest of the dark planet.

In the bottom picture, in the right corner, the record of thermal emission by the device Nircam (near infrared camera or “near infrared camera”), which operates in ranges invisible to the human eye. What we see is basically the light waves that the planet emits as it loses heat.

“The brightest region on the planet is where the sun is roughly at the top, because it is usually hotter. The brightness decreases towards the polar regions, which receive less sunlight, and less light is also emitted from the more northern hemisphere. cooler, which is trending during the winter at this time of year,” NASA explains.

The new data makes it possible to analyze short-term and seasonal phenomena such as dust storms, ice clouds and weather changes throughout the day. Spectroscopy analyzes have already provided information about the types of rocks found on the surface of the Red Planet and the composition of its atmosphere.

NASA believes these observations will be of great value for future research on “regional differences across the planet and the search for trace gases in the atmosphere, including methane and hydrogen chloride.”
