Scientists have discovered enormous white dunes made of methane ice on Pluto. They were found in high-resolution images taken by NASA’s New Horizons spacecraft. KNAU’s Melissa Sevigny reports it’s a mystery how they formed.

In the last few years, Pluto has gone from being a fuzzy dot in the sky to a geologically active world of mountains, canyons, and heart-shaped glaciers. That’s thanks to NASA’s New Horizons spacecraft, which sailed by Pluto in 2015 to photograph it up close for the first time. The mission’s leader Alan Stern is currently on a book tour and visits Flagstaff today. He spoke with KNAU’s Melissa Sevigny from the road.

About 30 miles northeast of Flagstaff in a remote area of high desert, is a set of manmade craters blasted into an ancient lava flow. They were put there 50 years ago as a training site for astronauts preparing to walk and drive on the moon.

Astronomers at Lowell Observatory in Flagstaff have discovered a rare runaway star: a yellow supergiant. It’s the first time humans have ever observed one as it’s speeding through its galaxy at 300,000 miles per hour—so fast, it could cover the distance between L.A. and New York in 30 seconds. Here’s Lowell astronomer Phil Massey.

Tens of thousands of educators are poised for a statewide walk out tomorrow demanding more funding for K–12 schools and better wages for teachers and support staff. Communities are mobilizing to provide day care for the very students those teachers are fighting for. Non-profits, churches and other organizations are taking in kids for little or no charge during what will be the first educator strike in state history. The KNAU news team went out into the community to hear from some of those who’ve offered to care for students, and support teachers, while they go to bat.
