Trick or Treat! A Halloween Puzzle…

Thank you for visiting our blog and taking a guess about our Halloween image…

Well, it’s not a close-up of a leaf during peak foliage, it’s not our Sun, and it’s not part of a ghostly Halloween mask, either. You are looking at the most colorful moon in our Solar System, Jupiter’s Io. Io’s unusually bright yellow surface is full of active volcanoes fueled by molten rock exploding toward its surface. These volcanoes are so active, that they are effectively turning the entire moon inside out! And how’s this eerie fact just in time for Halloween — some of Io’s volcanic lava is so hot that it literally GLOWS IN THE DARK!!!! Booooo!!!
