ECOSTRESS acquired this image the night of July 9, 2018, over Egypt. Yellow and red indicate generally higher temperatures. The River Nile is visible as a thin blue line on the main image. The black-and-white inset shows the level of detail available from ECOSTRESS, with the relatively cool Nile River and surrounding vegetation appearing darker. https://photojournal.jpl.nasa.gov/catalog/PIA22590
