HiPOD: The Richness of Layers

This stunning image features dozens of layers in the walls of a graben on the flanks of Arsia Mons. These layers could be yet unmapped volcanic units (lavas or ash deposits) and their identification can lead to a greater understanding of the history of this volcanic terrain. Material from this wall likely mantled the ice-rich deposits on the graben floor, and a 3D model can also characterize erosion patterns on the wall.

Enhanced color cutout is less than 1 km across; grayscale is less than 5 km. For full image including scale bar, visit the source link.

Humans build buildings taller and wider than a tornado. Humans make pools longer than a tall building. Humans can forcibly plant lavender (which this is not a picture of) in fields longer and wider than an airport runway.

Meet Davy’s naked-backed bat (Pteronotus davyi)! This species, which can be found in parts of Central and South America, preys mostly on moths and flies. It uses echolocation to hunt by night, and can detect prey as small as 0.08 in (0.2 cm) in size from nearly 2.46 ft (0.75 m) away in darkness. Often feeding above water, this bat also has the ability to drink on the go—a phenomenon known as “drinking on the wing.”

Auroras from Space Image Credit: ESA, NASA, ISS Expedition 74; Capture: Sophie Adenot; Music: Circle of Light (Patrick Hawes & Grace Davidson)

Explanation: What do auroras look like from above? Behold! From the ground, auroras dance high above clouds, frequently causing spectacular displays. From space, they look a bit different. As the International Space Station (ISS) circles the Earth every 90 minutes, it sometimes sees auroras below that are active on the night side. A one-hour time-lapse video showing auroras from above was captured about two weeks ago from the orbiting ISS. The ISS -- and all objects in low Earth orbit -- will pass well above green auroras but just a bit above red glowing auroras. The auroras' electron and proton streams are too thin to be a danger to the ISS, just as clouds pose little danger to airplanes. From orbit, as magnetic fields change, auroras can appear to squiggle and crawl like giant snakes. The featured one-minute video was captured by French astronaut Sophie Adenot of the ISS Expedition 74 crew.
