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.


Earth Notes: Quiet Parks

Bugling elk, rolling thunder, the delicate trill of a hummingbird’s wings. These natural sounds can be heard in America’s national parks—some of the quietest places on Earth.

Total solar eclipses cast an eerie darkness over the day, but astronomers say that's an ideal time to study the sun. Jeff Hall is an astronomer and sun expert at Lowell Observatory. He says when the sun’s brilliance is blocked out by the moon, other solar features appear.

Planetary scientists in Flagstaff study Mars as if they are there. And virtually, they are. Northern Arizona University’s Mars Lab immerses them into the Martian environment with the aid of 3D goggles and the latest images from the Curiosity Rover and orbiting satellites. Christopher Edwards runs the Mars Rover Operations and Analysis Laboratory where he can explore old lake beds, collapsed lava flows, shifting sand dunes and rocky ridges. 


A rare “super bloom” is rolling across the Southwest this spring. A late, wet El Niño pattern has caused an explosion of wildflowers from the Pacific Ocean, to the Mojave Desert, to the mountains of northern Arizona. Brian Klimowski is a meteorologist with the National Weather Service in Flagstaff.
