Ring of Fire in the Sky

Portuguese photographer Rui Santos captured this shot of the recent solar eclipse.

Stunning. Here’s what makes this shot look a little different from other eclipse photos; from APOD:

Usually the solar corona appears white, and to some observers the corona of last week’s total solar eclipse did appear this pearly color. But this time, totality observers in Spain saw a corona that appeared unusually golden. For one reason, from Spain, the totality occurred when the setting Sun was near the horizon. That low, sunlight travels through a large amount of air which scatters out blue light. An unusual amount of smoke in the air from nearby forest fires acted as a second filter, further scattering the remaining blue tones and deepening the already gold-dominated light.

A Collection of Eclipse Glasses (1793-2019)

Oh wow, Williams College’s Hopkins Observatory has a huge collection of eclipse glasses & viewers (and other eclipse ephemera), some of them dating back to 1793. Here are a few of my favorites:

The coolest video of yesterday’s annular solar eclipse

Cory Poole made this video of the annular solar ecplise yesterday using 700 photographs from a telescope with “a very narrow bandpass allowing you to see the chromosphere and not the much brighter photosphere below it.”

Cory says: “The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.” Very cool.
