NASA's James Webb Space Telescope Captures Its First Images of Mars, Reveals Intriguing Details

 

Webb’s first images show a region of the planet's eastern hemisphere at two different wavelengths or colours of infrared light.


New views of our neighbouring planet, Mars, have been provided to us by NASA's James Webb Space Telescope, which is renowned for taking some amazing pictures of the cosmos. On September 5, the telescope obtained its initial views and spectra of Mars. In December 2021, the James Webb Space Telescope—a global partnership between NASA, ESA (European Space Agency), and CSA (Canadian Space Agency)—was launched. Last month, the telescope provided a close-up look of Jupiter that revealed its ring system and auroras.

Today, NASA announced the discovery of the Webb Telescope's first pictures of Mars in an official blog post. On the telescope's official Twitter account, NASA posted a message that describes Huygens Crater and Syrtis Major, a dark volcanic object  and Hellas Basin..



The Near-Infrared Camera captures Webb's first pictures of Mars (NIRCam). The eastern hemisphere of the earth is seen in these photos at two different infrared light wavelengths or colours.


The Mars team will reportedly use these images and spectroscopic data to investigate geographical variations on the planet in the future. They will also keep an eye out for signs of various gases in the atmosphere of the planet.

Astonishing images of Jupiter's beautiful auroras were acquired by NASA's James Webb Space Telescope (JWST) last month. The observatory's Near-Infrared Camera (NIRCam) was also used to take these pictures.


The spectrum displays the subtle variations in brightness between hundreds of different wavelengths that are representative of the planet as a whole, as opposed to the images, which show differences in brightness integrated over a large number of wavelengths from place to place across the planet at a specific day and time. To learn more about the surface and atmosphere of the planet, astronomers will examine the spectrum's characteristics.

The Mars team will eventually use this images and spectroscopic data to investigate regional variations throughout the planet and look for trace molecules in the atmosphere, such as methane and hydrogen chloride, according to NASA's blog.
