Of Note: Ever heard of a free floating planet not attached to a star? No? Neither had most people. This week NASA announced to the surprise of many that these solitary orbs do exist and may twice outnumber stars in the universe. Turns out that planets are exceedingly hard to find and cannot be seen at all if less than the size of Jupiter. One NASA official explained: "Although free-floating planets have been predicted, they finally have been detected. This has major implications for models of planetary formation and evolution." Some researchers postulate that the bodies are stars called Brown Dwarfs that simply did not "turn on." Others believe that the loaners have been ejected from solar systems by the gravitational pull of other stars or planets. Could be a little of each. A few scientists believe that our own solar system is populated with planets from outer space since the planets encircling our sun really don't match. We have the inner solid planets, an asteroid belt, then the large outer gaseous planets. Pluto, though not officially a planet any longer, is the real outlier. Ancient astrology even postulates that a few more invisible planets have yet to be discovered. Thus, just when we think there is little to learn about such a mundane topic as planets, along comes a new wave of discoveries. Many believe in the coming Age of Aquarius, this is just the beginning.
