My Humorous Science Fiction Story (about SETI) Recently Published


A brief short story I wrote -- about the first message we receive from an extra-terrestrial civilization -- has recently been published by the "SciPhi Journal" (an on-line magazine that specializes in philosophical science fiction.) You can read the story for free at:  
Perhaps the story can provide a touch of humor during these days of so much dark news. All the very best to everyone for a "cosmic" new year: may our planet becomes a better world for all of us.

My Second Published Science Fiction Story Now Available Free On Line

No photo description available.


 As some regular readers know, one my recent projects is writing short science fiction stories based on good astronomy. After a long learning period, two of my stories have now been published in science fiction anthologies. The second one, which is about exploding stars and music, just had its rights returned to me, and so I am happy to put it up free on the web for everyone's enjoyment at: 
After the short story, I have put a non-technical explanation of the science behind the fiction.
The accompanying photo is a NASA composite showing the remnant of Tycho's Supernova, a star seen to explode by the great astronomer Tycho Brahe in October 1604. In this image, blue and green colors shows what the remnant would look like if you had x-ray eyes, the yellow shows what it looks like in visible light, and the green shows the heat rays (infrared) coming from the object. Blended together, all the colors show where this remarkable "left-over"of a star that blew itself to bits is still glowing brightly more than 400 years later.
By the way, if you also want to read my first published science fiction story "A Cave in Arsia Mons" (about a surprising discovery on Mars), you can do so at:

My Talk to the Commonwealth Club on the Moon


The Commonwealth Club of California invited me to give an illustrated public talk about the Moon on the occasion of the 50th anniversary of the first human steps on our neighbor world. The video record is now available free on the Web, so if you are any of your friends (or students) are interested, you can find it at: https://www.commonwealthclub.org/…/astronomer-andrew-frakno…
I wanted to speak not so much about the astronauts and their journey (which so many other media and articles are covering in vast depth) but about the Moon itself, and what we now know about it, 50 years later. Hope you enjoy.
An audio-only version of the talk is also available as a podcast, at: https://www.commonwealthclub.org/events/archive/podcast/astronomer-andrew-fraknoi-50-years-our-first-step
The photo shows the Moon in front of a full Earth as seen from millions of miles away by the Deep Space Climate Discovery Spacecraft in 2015.

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/
[Our photo is by astronomer Rick Fienberg and shows a sequence of images before, during, and after a total 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.
