Explanation: Looping through the Jovian system in the late 1990s, the Galileo spacecraft recorded stunning views of Europa and uncovered evidence that the moon’s icy surface likely hides a deep, global ocean. Galileo’s Europa image data has been remastered here, using improved new calibrations to produce a color image approximating what the human eye might see. Europa’s long curving fractures hint at the subsurface liquid water. The tidal flexing the large moon experiences in its elliptical orbit around Jupiter supplies the energy to keep the ocean liquid. But more tantalizing is the possibility that even in the absence of sunlight that process could also supply the energy to support life, making Europa one of the best places to look for life beyond Earth. What kind of life could thrive in a deep, dark, subsurface ocean? Consider planet Earth’s own extreme shrimp.
A young Catholic priest decided to enter a monastery. He joined one particularly strict sect. The head monk told him, at his indoctrination, that they were sworn to TOTAL silence. They could not speak one word at all. However, every ten years, they would be permitted to speak two words.
After 10 years of total silence, the head monk indicated it was now time for him to speak his two words. The monk said, “Bed hard!” And then he resumed his silent study and work.Another 10 years passed and the head monk again indicated it was time for him to speak his two words. The monk said, “Food bad!” And then he resumed his silent study and work.Another 10 years passed and the head monk again indicated it was time for him to speak his two words. The monk said, “I quit!”
The head monk shook his head and said, “I knew this was coming. You’ve done nothing but complain for the past 30 years!”
