Pythagorean Astronomy: Backyard Worlds

February saw the first launch of SpaceX’s Falcon Rocket from Launchpad 39A – the same launchpad used by the Apollo missions and the Space Shuttle. In this month’s Pythagorean Astronomy, Edward Gomez and Chris North discuss these impressive structures along with the study of a supernova (the explosive death of a massive star) just hours after it exploded, providing crucial insights into the very early stages of these extreme events.

A new Zooniverse project, Backyard Worlds: Planet 9, was also announced designed to let “citizen scientists” (i.e. you!) help track down Planet Nine – whose existence was seriously proposed a year ago. Project leader Marc Kuchner told us about that project.

For those wondering, we recorded this before the announcement of both TRAPPIST-1 and the SpaceX announcement of their planned lunar missions – but they’re pretty safe bets for discussion next month!
