About Sky Lights

Dan Heim

Greetings fellow skygazers. 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, climatology, chemistry, physics, optics, earth & space science, and others. We’re also concerned about light pollution, and what can be done to preserve the darkness of our night sky.

Our posts alternate among several themes: “Reader Q&A”, “What’s Up Tonight?”, “Things Skygazers Should Know”, “Debunking Pseudoscience”, “Sharing Amazing Photos”, and “Climate Change”. Content is driven primarily by reader questions and feedback. Comments and Questions are solicited, and each post remains open to C&Q for one week.

All posts include multimedia to help clarify concepts. We try to keep things simple, with a minimum of scientific jargon and equations. We strive to both entertain and educate our readers. Welcome to the Sky Lights classroom!
