Dan’s latest: Yet Another Planetarium Simulation

Great news! Dan Schroeder, the physics professor whom some of you will remember from his excellent reviews of iPhone astronomy apps, has written his own astronomy applet. Give it a look.

Why write another astronomy program? Here’s Dan’s answer.

To be useful to most of my students, a simulation program has to be (a) free; (b) delivered through a web browser, with nothing to download or install; (c) easy for beginners to understand; and (d) convenient for showing the motions of the stars and other objects with respect to earth’s horizon.

It’s a lot of fun to play with, and I like how Dan notes that his UI was partially inspired by H.A. Rey’s stargazing books, of which I too was, and remain, a loyal fan.
