Two new books chronicle Flagstaff’s long history with everybody’s favorite dwarf planet, Pluto. It was discovered at Lowell Observatory in 1930 and it’s been the toast of the town ever since. Local scientists have been involved with nearly every major Pluto discovery, including the recent flyby by NASA’s New Horizons spacecraft. KNAU’s Melissa Sevigny brought the authors of the new books into the studio to have a conversation about why they think little Pluto is a big deal for Flagstaff.

A year from today, NASA scientists will have a chance to explore a small space rock in the outer solar system. It will be the most distant object ever visited by a spacecraft. KNAU’s Melissa Sevigny reports.

Astronomers in Arizona and worldwide are running a “planetary defense drill” to practice how to deal with an asteroid impact. It’s the first time they’ve used a real asteroid. KNAU’s Melissa Sevigny reports.

Today’s full solar eclipse was the first in 100 years to stretch from coast to coast in the U.S. Millions of people flocked to the 70-mile-wide path of totality, and one of them is KNAU’s science reporter Melissa Sevigny. She’s on the line with me from Madras, Ore., which was in the center of the path of totality.
