Revealing #palimpest with #multispectral #imaging! These amazing results, showing a #Merovingian overtext and a 5th-century Gospel undertext, were achieved by my colleague Alex Zawacki at Göttingen. I'll be presenting the full results of this and other cool discoveries in May at a German-language conference in Kiel.

A false-color #multispectral photo I took of a larkspur with UV and IR light mapped on top of a regular visible-color photo. Inner parts of the flower petals reflect more UV than others and thus show up in blue. Other parts absorb UV but reflect IR, resulting in the red colors seen in the inner part of the flower and stems. Many flowers use this contrast to help pollinators (who often can see UV) to distinguish key parts of the flower.

“With a trio of smaller satellites that can each detect 26 wavelengths of light, the Landsat Next mission is expected to look very different from its predecessors that have been observing Earth for 50 years. This new plan for Landsat Next, a joint mission of NASA and the U.S. Geological Survey, is designed to provide more frequent, and finer resolution, data of the changing surface of Earth…”
