NASA’s Mars Reconnaissance Orbiter Finds Hydrated Silica in Jezero Crater

This image from NASA’s Mars Reconnaissance Orbiter shows Jezero Crater on Mars, the landing site for NASA’s Mars 2020 mission. On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit show that some of these sediments have minerals that indicate chemical alteration by water. Here in Jezero Crater delta, sediments contain clays and carbonates. Image credit: NASA / JPL-Caltech / MSSS / JHU-APL.

Using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument aboard NASA’s Mars Reconnaissance Orbiter, researchers have detected hydrated silica — a mineral good at preserving biosignatures — in Jezero Crater, the landing site of the agency’s upcoming Mars 2020 rover mission. This image from NASA’s Mars Reconnaissance Orbiter shows Jezero Crater on Mars, the landing site for NASA’s Mars 2020 mission....

This image snapped by the NASA/ESA Hubble Space Telescope reveals a detailed view of the central part of the unbarred spiral galaxy NGC 772. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Seth et al.

This Hubble image shows a massive galaxy cluster, about 4.6 billion light years away. Along its borders 12 images within the four arcs are visible; these are copies of the same galaxy called PSZ1 G311.65-18.48, which is almost 11 billion light-years away. Three of these arcs are visible in the top right of the image, while one counterarc is visible in the lower left -- partially obscured by a bright foreground star within our Milky Way Galaxy.
