The spectral signatures – including deep valleys known as absorption features – of water, carbon dioxide, and carbon monoxide are easily detected with Webb in these observations. Analyzing the spectrum shows a rich set of spectral features that detects information about dust, icy clouds, rocks on the surface, and the composition of the atmosphere. The second image shows Webb’s first near-infrared spectrum of Mars, proving Webb’s power to study the Red Planet with Spectroscopy. The near-infrared images from Webb are on shown on the right. The image combines a surface reference map from NASA and the Mars Orbiter Laser Altimeter (MOLA) on the left, with the two Webb NIRCam instrument field of views overlaid. The first images of Mars captured by the Near-Infrared Camera (NIRCam) of James Webb Telescope, show a region of the planet’s eastern hemisphere at two different wavelengths, or colors of infrared light. The Webb Telescope provides a view of Mars’ observable disk in order to capture images and spectra with the spectral resolution needed to study phenomena like dust storms, weather patterns, seasonal changes, and, in a single observation of a Martian day.Īs Mars is so close, the bright infrared light from Mars is blinding for the telescope, causing a phenomenon known as “detector saturation.” Scientists used very short exposures and special data analysis techniques to capture these images from the James Webb Telescope. The James Webb Telescope, provides a unique perspective with its infrared sensitivity on our neighboring planet, complementing data being collected by orbiters, rovers, and other telescopes. NASA’s James Webb Space Telescope has released its first images and spectra of Mars from observations made on Sept.
