I'm an astronomer at Lowell Observatory, in Flagstaff, Arizona, building & using
the highest resolution optical telescopes available on the planet.
I use these telescopes to learn about the sizes, shapes,
and surfaces of stars, and to look for planets orbiting those stars.
Phenomena to Look For During the Eclipse
- Baily's Beads - See the Sun as it starts to peek between the hills & craters of the moon
- Chromosphere - The solar chromosphere, a layer that sits right above the photosphere (the shining surface of the sun), is normally obscured from view by the overwhelming brightness of that photosphere
- Corona - The solar corona, a multi-million mile, million-degree superheaded aura of plasma that surrounds the sun
Eclipses in History
- The 1868 Solar Eclipse - Jules Janssen took spectra of the solar chromosphere during an eclipse and found features that had been previously undetected, due to a previously unknown element - helium
- The 1919 Solar Eclipse - Taking advantage of the conditions of an eclipse, two expeditions definitively proved Einstein's general relativity, catapulting him to international superstardom
- A 1946[?] Solar Eclipse - A solar eclipse saves Tintin, Captain Haddock, and Professor Calculus!
