Hey Space Placers!Pi recently played a crucial role in new discoveries about Alpha Draconis, a well-studied pair of stars. After discovering these stars regularly eclipse each other, pi helped scientists learn more about them. Scientists detected the eclipses while monitoring the brightness of Alpha Draconis for periodic dips that could’ve been caused by planets passing between the star and us. Instead of a planet, though, researchers found that its smaller partner in crime was passing in between us and the larger star for about six hours at a time! 💫CREDIT: NASA3/14 is National Pi Day.See how NASA uses Pi and where Pi comes in handy in the Universe.While contemplating Pi and the Universe here are two other items of recent interest about our Universe:LHC discovers four new particles which plainly shows we don't know everything about the universe of the very, very small particles that make up the Universe - and us!A great article on why astronomers think Dark Matter exists.Oh, and enjoy your Earth bound pie today on Daylight Savings Time (in the U.S.)Sky Guy in VA
