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

- 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.

NASA's Mars 2020 Perseverance rover has a challenging road ahead: After having to make it through the harrowing entry, descent, and landing phase of the mission on Feb. 18, 2021, it will begin searching for traces of microscopic life from billions of years back. That's why it's packing PIXL, a precision X-ray device powered by artificial intelligence (AI).

What's the most interesting fact you know about Uranus? The fact that its rotational axis is completely out of line with every other planet in the solar system? Or that Uranus' magnetosphere is asymmetrical, notably tilted relative to its rotational axis, and significantly offset from the center of the planet? Or that its moons are all named after characters from Shakespeare or Alexander Pope?
