the sun, the moon, and the stars at instructivist

Incredibly cool post at Instructivist!

C. & Ed are going to love it.

While you're there, be sure to read his post on the NY Regents History exam, too. The suffragette question reminds me of Celebrity Jeopardy.

I am excited myself about these images even though Betelgeuse and Antares make me dizzy. Thanks for posting. (For some reason, the link to my post doesn't work. Google idiosyncracy?)

A bit of esoterica about the name Betelgeuse. It is a faulty transcription from the Arabic. Apparently, the first letter should have been a Y but the transcriber overlooked a dot in the Arabic letter (bad eyesight?) which turned it into a B.

I thought you might want to know (grin).

Transcription should have been transliteration.

I'll fix it - thanks!

(Usually I check links ----)

Yes, those images are incredible.

Should be working now.

I just looked at the sequence.

(working too fast last night to study it)

I actually didn't know Mars was so small compared to the Earth.

And looking at the sun compared to Sirius, Pollux, etc.---
