According to MSL scientists based at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., the ball isn't as big as it looks — it's approximately one centimeter wide. Their explanation is that it is most likely something known as a "concretion." Other examples of concretions have been found on the Martian surface before — take, for example, the tiny haematite concretions, or "blueberries", observed by Mars rover Opportunity in 2004 — and they were created during sedimentary rock formation when Mars was abundant in liquid water many millions of years ago.

College classes, which used to only cover old-fashioned concepts like math and Beyoncé, are finally getting with the times and taking on the subjects that really matter. No, not computer programming or military drone maintenance, we're talking about the Marvel Cinematic Universe. According to The Hollywood Reporter, Baltimore's University Of Baltimore—home of the Fightin' Poes—is now offering a class on Marvel's movies and their "important insights into modern culture." The class will apparently focus on the ways that movies like Guardians Of The Galaxy and The Avengers explore issues like "the nature of heroism," "our willingness to trade freedom for security," and, obviously, "the great responsibilities that come with wielding great power."
