HAMPTON, Va. (AP) — A discussion at NASA’s Langley Research Center in Hampton is exploring oceans at the edge of the solar system.

Officials say Kevin Hand from NASA’s Jet Propulsion Laboratory will present “Ocean Worlds of the Outer Solar System” Tuesday afternoon.

He’ll present a similar program at the Virginia Air & Space Center in downtown Hampton on Tuesday night.

Hand is the deputy chief scientist for solar system exploration at the Jet Propulsion Laboratory in California.

Officials say at least five moons in the outer solar system may have liquid water oceans. These oceans are considered good candidates for NASA’s search for life beyond Earth.

Hand will explain the science behind why researchers think they know these oceans exist, and what they know about the physical and chemical conditions on these worlds.
