LOS ANGELES — Amateur astronomer William Bianco doesn’t huddle over a backyard telescope to hunt for undiscovered planets. He logs onto his computer.

That's a telescope and the astronomer at Washburn, Jim Lattice, well, he turns to me, and he said, well, I'll look through it from the studios of Cincinnati public radio.

Astronomers have been using NASA’s James Webb Space Telescope to collect data from K2-18 b, a planet about 8 times bigger than Earth that was first discovered in 2015.
