SciShow Asks ‘Bad Astronomer’ Phil Plait How We Measure the Distance of Stars

Host Hank Green welcomes guest Phil Plait from the Bad Astronomy blog and asks him how we measure the distance of stars in a recent episode of SciShow (see previously).

The episode is part of “School of YouTube Week,” a charity promotion by YouTube and Comic Relief that asks popular YouTube channels to focus on learning or teaching something, and asks viewers to donate to help fund education for children in impoverished nations.
