California Desert Dunes Hold Keys to Understanding Mars' Shifting Sands

Armed with a drone and a device which is a cross between a scoop and a spatula, a graduate student is cracking the code of Mars by studying California's desert dunes. By comparing wind carved patterns in the Algodones Desert with satellite images of the Red Planet, researchers are creating humanity's first comprehensive database of Martian sand formations, work that could determine where future astronauts can safely establish bases without getting buried alive. Her pioneering research proves that sometimes the keys to exploring alien worlds aren't found in billion dollar space missions, but in the shifting sands right here on Earth.

Are We in a Giant Void? That Would Help Explain the Hubble Tension

It's assumed that our region of the Universe isn't special, and the Hubble Tension, or mismatch of expansion rates of the Universe at different times, is happening everywhere. But what if our place is unusual, for example, if the Milky Way is inside a lower-density region of the Universe, with stronger gravity pulling material away from us in all directions? A new paper suggests we might be in a void that's emptying out towards higher-density regions all around us.
