“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside. Participants learn that planetary scientists at NASA are investigating “icy worlds” in the outer solar system, looking for evidence of liquid water and possible signs of life beneath the icy surface.
- Ocean worlds may be the most likely places to discover life beyond Earth.
- Scientists think that ocean worlds have ice-cold frozen exteriors, and warmer, liquid interiors.
- Some astrobiologists are studying ocean worlds for evidence and signs of life.
