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

On June 25, 2021, the Office of the Director of National Intelligence released a much-anticipated report on UFOs to Congress. The military has rebranded unidentified flying objects as unidentified aerial phenomena—UAPs—in part to avoid the stigma that has been attached to claims of aliens visiting the Earth since the Roswell incident in 1947. The report presents no convincing evidence that alien spacecraft have been spotted, but some of the data defy easy interpretation.

China landed a spacecraft on Mars for the first time on Saturday, a technically challenging feat more difficult than a moon landing, in the latest step forward for its ambitious goals in space.

Almost half a century ago the creators of Star Wars imagined a life-sustaining planet, Tatooine, orbiting a pair of stars. Now, 44 years later, scientists have found new evidence that that five known systems with multiple stars, Kepler-34, -35, -38, -64 and -413, are possible candidates for supporting life. A newly developed mathematical framework allowed researchers at New York University Abu Dhabi and the University of Washington to show that those systems—between 2764 and 5933 light years […]

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.
