The late Paul Allen’s research vessel, the Petrel, has found another historic warship at the bottom of the ocean. In the wake of an initial discovery in late January, the expedition crew has confirmed that it found the USS Hornet, an aircraft carrier that played a pivotal role in WWII through moments like the Doolittle Raid on Japan and the pivotal Battle of Midway.
In 1960, the US Air Force asked the RAND Corporation to evaluate the possibility of using stationary rockets to pause the Earth’s rotation in the event of a nuclear attack. Called “Project Retro,” the idea was that the “a huge rectangular array of one thousand first-stage Atlas engines… (would) be fastened securely to the earth in a horizontal position.” As missiles approached, the rockets would fire, stopping the Earth’s rotation just enough for the nukes to overshoot their targets.

Scientists have long believed that our solar system might have a ninth planet orbiting well beyond Neptune and Pluto. Scientists hypothesize that the mysterious planet would be between five and 20 Earth masses and would orbit on an elliptical some hundreds or thousands of times more distant from the Sun than the Earth.
All things considered, outer space is a pretty terrifying place. It’s utterly silent, unfathomably vast, and it experiences weather extremes that make Earth’s seem mild in comparison. And then there’s the radiation. We’re pretty much protected from hazardous levels galactic cosmic rays (GCRs) by our planet’s magnetic field but, just past low orbit, high-energy protons and charged particles can cause serious health and cognition problems.

Researchers have discovered a “rogue” planet outside of our solar system using the Very Large Array (VLA), the first time such a discovery has been made using a radio telescope. The planet is called rogue due to its lack of a parent star, having the distinction of being something between a planet and a brown dwarf
