On Monday the long-anticipated “Great American Eclipse” will cross the country coast-to-coast from Oregon to South Carolina. Scientists will watch the sun vanish behind the moon using telescopes on the ground and from weather balloons and planes. But what are they looking for? KNAU’s Melissa Sevigny spoke with Lowell Observatory astronomer Gerard van Belle about science that can only be done during a total solar eclipse.

Eclipse Chasers Flock To Path Of Totality

Aug 17, 2017

We are now days away from, what some scientists call, “the most beautiful event in the sky,” a total solar eclipse. Only some US cities will be lucky enough to see the moon completely overtake the sun on Monday, when it a casts a long, thin shadow across the country. KNAU’s science reporter Melissa Sevigny is on her way to Madras, Oregon, one of the cities located in, what’s known as, the path of totality. Melissa spoke with KNAU’s Aaron Granillo before she took off.

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.

Flagstaff is a research hub for "near Earth objects"—space rocks that zip through our cosmic neighborhood. More than a thousand new objects are found every year and some of them could pose a threat to Earth. KNAU’s Melissa Sevigny reports on the people who keep a close eye on the skies.
