Total Eclipse of the Sun in South America July 2; Future U.S. Eclipses


Tomorrow, July 2, there will be a total eclipse of the Sun visible in Chile and Argentina. A live webcast is planned at: https://www.exploratorium.edu/eclipse
Another total eclipse will be visible from southern South America on Dec. 14, 2020.

Looking further ahead, an annual eclipse will be visible on a path that goes across the U.S. on Oct. 14, 2023.
And Apr. 8, 2024 another total eclipse will sweep across the U.S. from Texas to New England. For a clear map of this eclipse, see: https://www.greatamericaneclipse.com/april-8-2024
(Shameless plug: Dennis Schatz and I have written a children's book all about eclipses, called "When the Sun Goes Dark," for the non-profit National Science Teachers' Association Press. See: https://www.nsta.org/store/product_detail.aspx… )

A free app about eclipses, called "Totality" is available from astronomer Jeff Bennett, at: https://www.bigkidscience.com/eclipse/

A Blog Features my New Catalog of Music Inspired by Astronomy


Over the years, I have collected many examples of music inspired by astronomical ideas and discoveries.  (I did this with help from students and colleagues.) Now I blush to report that Sky & Telescope magazine has done a blog post on my latest catalog of astronomical music (with over 250 pieces listed.) 

You can read the post (and get a link to the catalog) at: https://www.skyandtelescope.com/…/…/music-astronomy-catalog/

I hope some of the pieces listed might bring you some musical pleasure.

Government Shutdown Expands: Moon Goes on Furlough Tonight


In the above table, you can see the timing of tonight total eclipse of the Moon for all the North American time zones. Click on the image to see it bigger.
Don't worry about the first and last rows of the table. Just focus on when the partial eclipse begins (when the Earth's shadow first starts to move across the Moon) and when the total eclipse begins (the Moon is full covered by shadow and turns red.)
Remember, if there are clouds, this eclipse last a long time, so come back out after a few minutes and see if you can glimpse the Moon. Often the Moon plays hide and seek with layers of clouds, and patience will pay off.
Full details of the eclipse and what to watch for are here:

Thanks to Sky & Telescope magazine for the table.  The composite photo below is by amateur astronomer and NASA educator, Brian Day.  Note the Earth's round shadow in the outer images and the coppery red color of the eclipsed Moon (the Earth's atmosphere bends red colors of light more effectively than other colors on to the shadowy face of the Moon.)

Heads Up: Total Eclipse of the Moon Sunday Evening January 20



On Sunday evening, January 20, there will be a nice total lunar eclipse (where the Earth’s shadow darkens the full moon) visible in all of North America. Since this is the day before Martin Luther King Day in the U.S., many students will not have school the next day and can stay up to enjoy the celestial spectacle with their families.
Total eclipses of the Moon are perfectly safe to look at, don’t require special viewing equipment, and are visible all over one hemisphere of planet Earth. Your eyes are just fine to see the show. This is quite a contrast with the total eclipses of the Sun, where viewing can sometimes hurt your eyes, special equipment is a big help, and the best show is only visible in a narrow path. As Bernie would say, the lunar eclipse is for the 99%, not just the special 1%!
A more detailed information sheet I put together (with questions and answers, plus the timing in each time zone of the continental U.S.) can be found at:

Here is wishing you a cloudless evening, and a few hours thinking about the heavens and not the craziness in Washington.
