About Sky Lights

Sky Lights is a weekly blog about things you see in the sky (and a few you can’t see). That covers a wide range of disciplines including: astronomy, meteorology, chemistry, physics, optics, earth & space science, and others. We’ve discussed everything from meteors to rainbows to black holes. We’re also concerned about light pollution, and what can be done to preserve our view of the dark night sky.

My posts alternate between “Q&A” and “What’s Up Tonight?” Every post includes graphics, photos, or animations to help clarify the concepts. We try to keep things simple, with a minimum of scientific jargon and equations. We hope to both entertain and educate our readers. Welcome to our hilltop observatory!
