For the trivia buffs out there, I present a challenge. I will give away a SpaceTalkNOW t-shirt to the first 10 people who can correctly answer my trivia question.
Which is brighter?
a) a full moon, or
b) two half moons
I’ll also include a mug for those who can go the next step and explain why.
Send your entry to trivia@SpaceTalkNOW.org and be sure to include your name.
