In 1894, with the help of William Pickering, Percival Lowell, a wealthy Bostonian, founded the Lowell Observatory in Flagstaff, Arizona. In 1906, convinced he could resolve the conundrum of Uranus’s orbit, he began an extensive project to search for a planet beyond Neptune, which he named Planet X, a name previously used by Gabriel Dallet. The X in the name represents an unknown and is pronounced as the letter, as opposed to the Roman numeral for 10 (at the time, and now, Planet X would be the ninth planet). — Wikipedia

A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: A hypothesized, distant body in our solar system dubbed "Planet Nine."

When they reached Mars' surface in 1976, NASA's two Viking landers touched down with a gentle thud. At 7 feet tall, 10 feet long, and weighing around 1,300 pounds, these spacecraft—the first U.S. mission to successfully land on the Martian surface—looked like overgrown pill bugs.
- Do octopuses' arms have a mind of their own?on November 2, 2020 at 5:45 pm
Often described as aliens, octopuses are one of most unusual creatures on the planet, with three hearts, eight limbs and a keen intelligence. They can open jars, solve puzzles and even escape from their tanks, aided by their eight ultra-flexible and versatile arms. But determining how exactly octopuses control all eight limbs is a puzzle that scientists are still trying to crack.

The search for Planet Nine—a hypothesized ninth planet in our solar system—may come down to pinpointing the faintest orbital trails in an incredibly dark corner of space.

Three scientists won the Nobel Prize in physics Tuesday for establishing the all-too-weird reality of black holes—the straight-out-of-science-fiction cosmic monsters that suck up light and time and will eventually swallow us, too.
