Halloween is in the air! Get ready for a spoooooky episode where we take a stroll through the haunted side of the Universe. Alex takes us on a trek through a graveyard to investigate the skeletons the Milky Way is hiding – and no, we’re not talking about the candy! Then Will tells us a ghost story about the old blue monsters hiding under our extragalactic beds, but don’t worry too much. He reassured us that they only eat dust.
