On Aug. 4, 1972, the crew of a U.S. Task Force 77 aircraft flying near a naval minefield in the waters off Hon La observed 20 to 25 explosions over about 30 seconds. They also witnessed an additional 25 to 30 mud spots in the waters nearby.
Destructor sea mines had been deployed here during Operation Pocket Money, a mining campaign launched in 1972 against principal North Vietnamese ports.

On October 19, 2017, astronomers first saw an object from another solar system traveling through our own. Zipping into our solar system from above, the interloper, now known as 1I/2017 U1 (‘Oumuamua), swung around the Sun and shot away again, never to return once it leaves our neck of the woods for interstellar space once more.
What have we learned about thi ...read more
