Nearly 25 years ago, the Pathfinder spacecraft explored a suspected floodplain on Mars. Unbeknownst to NASA at the time, the waters that long ago carved Pathfinder’s landing site spilled out from a previously undocumented inland sea nearby, new research shows.

A 'Hairy Blue Spider' on Mars Is One of the Cool New Scenes Captured by European Orbiter A 'Hairy Blue Spider' on Mars Is One of the Cool New Scenes Captured by European Orbiter

Sadly, David Bowie was wrong about spiders on Mars, despite this exciting new image of what appears to a gigantic blue tarantula on the Martian surface. In reality, the false-color picture shows a series of trails produced by Martian dust devils. The photo is one of many captured by Europe’s ExoMars Trace Gas Orbiter,…

We Can Thank Agriculture and Soft Food for the 'F' Word, Claims Provocative New Study We Can Thank Agriculture and Soft Food for the 'F' Word, Claims Provocative New Study

Humans couldn’t always easily produce “f” and “v” sounds, according to a surprising new study. The reason we can now enjoy words like “flavor” and “effervescent,” say the researchers, has to do with changes to the ancestral human diet and the introduction of soft foods—a development that altered the way we bite, and…

Earth's Low Orbit Needs Legal Protection Before It Becomes a Cosmic Junkyard Earth's Low Orbit Needs Legal Protection Before It Becomes a Cosmic Junkyard

The area immediately above our planet where most of our satellites live might seem like an inexhaustible place, but it’s not. Low Earth orbit is quickly filling up with all sorts of junk, and the potential for a disaster has never been greater. Here’s how laws and international treaties can help—and why we need to…

NASA Captures First-Ever Images of Intersecting Shockwaves From Two Supersonic Jets NASA Captures First-Ever Images of Intersecting Shockwaves From Two Supersonic Jets

An air-to-air imaging technology developed by NASA has resulted in the first images ever taken of interacting shockwaves produced by in-flight supersonic jets. The new images, in addition to being beautiful, will help NASA design jets capable of producing gentle rumbles instead of loud sonic booms when breaking the…
