It was a marvelous night for a moon dance at the annual Spring Dance Festival in Flagstaff presented by Canyon Movement Company. This year’s theme was the Apollo missions. How do dancers translate science onto the stage? In this installment of Eats and Beats: Stories about Food and Music, we hear three choreographers explain how they used music and movement to cast a different light on the moon.

A space mission led by the University of Arizona has been orbiting a near-Earth asteroid for the past three months. It’s turned up a few surprises, including plumes of dust and rubble that erupt off the asteroid’s surface into space. KNAU’s Melissa Sevigny reports.

A total lunar eclipse will be visible throughout North and South America on Sunday night. KNAU’s Melissa Sevigny reports on the best time for Arizonans to watch the moon plunge into Earth’s shadow.

Earth’s shadow will take the first bite out of the moon at eight thirty in the evening, as it rises in the eastern sky. The eclipse will end just before midnight.

NASA’s New Horizons spacecraft beamed back the first close-up image of its target, Ultima Thule, revealing it’s a “contact binary”—two space rocks stuck together. KNAU’s Melissa Sevigny reports.

This is the most primitive contact binary ever explored by a spacecraft. It likely formed four and a half billion years ago by a process called “accretion.” Particles of rock and rubble melded into two round objects, which then slowly spiraled together until they stuck.
