Researchers have identified more than 100 giant exoplanets that may have potentially life-hosting moons. The new analysis could change the way scientists search for life in the cosmos, study team members said.

That search has generally focused on places more or less like Earth — rocky planets in the „habitable zone“ of their host star, that just-right range of distances where liquid water could exist on a world’s surface. Jupiter-like planets don’t seem like good candidates in this regard, because they have no discernible surface. But the rocky moons of such gas giants may be a different story, study team members said. [How Habitable Zones for Alien Planets and Stars Work (Infographic)]
„There are currently 175 known moons orbiting the eight planets in our solar system,“ study co-author Stephen Kane, an associate professor of planetary astrophysics at UCR and a member of UCR’s Alternative Earths Astrobiology Center, said in a statement.
