Indian River State College recently held a “brain bowl” for its students, who compete to answer questions on music, art, literature, history, geography, philosophy, math and science. In honor of the brain bowl, here’s a quiz for you: Where is the Sea of Serenity? What is Newton’s Third Law of Motion? What’s the tallest volcano in the solar system? Which star is closest to earth? What is New Horizons? Here are the answers: The Sea of Serenity is a dry lava basin on the moon. Newton’s Third Law states that for every action there is an equal and opposite reaction. The tallest volcano is fifteen-mile-high Mt. Olympus on Mars. The nearest star after the sun is Proxima, part of the Alpha Centauri system, 25 trillion miles away. And New Horizons is a spacecraft that was launched toward Pluto; it reached this distant world a couple of years ago and sent back incredible images of Pluto and its moons.
