Bennu is a small, near-Earth asteroid that passes close to Earth about every six years. It was the target of NASA's OSIRIS-REx mission to collect an asteroid sample and bring it to Earth.

Former Port Jervis Science Teacher (and Radio Catskill volunteer) Joe Johnson talks about the surprising  phosphate finding in the asteroid sample, as well as other science stories that caught his eye: 'dark oxygen' produced four thousand meters below the ocean's surface and the mysterious 'dark fungi' lurking everywhere.
