The moon is drifting away from us. Each year, our moon moves distinctly, inexorably farther from Earth—just a tiny bit, about an inch and a half, a nearly imperceptible change. There is no stopping this slow ebbing, no way to turn back the clock. The moon used to be closer. When it first formed, about 4.5 billion years ago, molded out of rocky debris that had been floating around Earth, the moon orbited 10 times nearer to the planet than it does today.

NASA is set to launch a spacecraft next month on the agency's first mission to a group of asteroids near Jupiter. The Lucy space probe is scheduled to lift off on an Atlas V rocket from Cape Canaveral Space Force Station in Florida on Oct. 16. NASA's Juno spacecraft has been circling Jupiter since 2016, but this will be the agency's first expedition to study two swarms of space rocks at the gas giant — one group that orbits the sun ahead of Jupiter and another that trails behind the planet.

But GW Orionis, a young, planet-forming system just 1,300 light-years away, has multiple protoplanetary rings orbiting a triple star system. A new study shows there must be planets in between those rings, making these the first planets discovered orbiting all three stars in a trinary system.

The strange celestial object, GW Ori, also has a disc split in two at a strange 38-degree angle – as if the rings of Saturn were broken in the middle and tilted askew.

The Lucy mission has passed all of its prelaunch tests and is set to leave Cape Canaveral Space Force Station at around 5:30 a.m. ET on October 16. The Trojan asteroids, which borrow their name from Greek mythology, orbit the sun in two swarms -- one that's ahead of Jupiter, the largest planet in our solar system, and a second one that lags behind it.

It is surrounded by a huge disk of dust and gas, a common feature of young star systems that are forming planets. But fascinatingly, it is a system with not one star, but three. As if that were not intriguing enough, GW Ori's disk is split in two, almost like Saturn's rings if they had a massive gap in between. And to make it even more bizarre, the outer ring is tilted at about 38 deg...
