♁ as NASA'S science news explains, a "super moon" will be dominating the sky on march 19th. basically, there's a fairly happy coincidence: a full moon just as our lunar neighbor's orbit brings it as close to earth as it gets. so the moon will appear much larger than normal, especially when its close to the horizon and what NASA calls the "moon illusion" sort of tricks our eyes into making it seem especially big.
♁ if you need me, ill be dancing around a bonfire and baying at the moon with the dogs
