What Is Space?

This is a blog post I wrote in March of 2008—a year before there was even Lights in the Dark! I’m sharing it again because it’s fun…I hope you think so too. We’ve all seen the grade-school models of the solar system. Maybe you made one in science class. Out of painted styrofoam balls or…

No, the Solar System (Still) Isn’t a Vortex

Like a bad penny (or a grossly inaccurate science meme) this tends to rear its shiny animated head online at least a couple of times a year, and it seems this year will be no exception. It’s a GIF showing the motions of the Sun and planets through space, trailing glowing lines (which they don’t…

Friday Fun: Plop Plop, Fizz Fizz…in Zero-G

During his 340-day-long One-Year Mission in 2015-2016 NASA astronaut Scott Kelly conducted—and was the subject of—countless experiments on the effects of long-duration space travel aboard the ISS.

Apollo 10’s “Outer-Space-Type Music” Explained

There’s been some buzz recently (no pun intended, Mr. Aldrin) concerning supposed “space music” heard by Apollo 10 astronauts while they were traveling around the far side of the Moon in May of 1969. This is in no small part due to the season three opener of NASA’s Unexplained Files* on the Science Channel, which aired on…
