Do planets circle our closest stellar neighbors, the system loved by science fiction: Alpha Centauri? We don’t know. But, Debra Fischer, Julien Spronck, and their colleagues at Yale University, in part with Planetary Society support, are trying to find out.
With the latest piece of the puzzle just published in a scientific journal, a solar system mystery that has perplexed people for more than 20 years has been solved, truly thanks to the support of Planetary Society members.
If you want to test your planetary knowledge, or just have a masochistic love of tests, I’ve posted the midterm I’ve given to my students in my online Introductory Astronomy and Planetary Science class at California State University Dominguez Hills.
I gave the first lecture of my Introduction to Astronomy and Planetary Science course last Wednesday, starting with a tour of the solar system. The course is Physics 195 at California State University Dominguez Hills.
