These mysterious starlike objects shine from the outermost limits of the universe, helping scientists learn about the earliest stages of existence. We’ve since learned that a quasar is actually a black hole at the center of a huge, distant galaxy. Perhaps more interesting, quasars give off 1,000 times more energy than the entire Milky Way galaxy.
You may have learned that some planets in the solar system are gaseous, but did you know that Saturn, that blinged-out planet with all the rings, could float in water? The planet’s density is 0.687 g/cm3 versus water’s density of .998 g/cm3. So Saturn would make an awesome rubber ducky in the universe’s largest bathtub. If only we had a prodigal billionaire to help make that happen. Paging Richard Branson?
