Surprising number of exoplanets could host life
A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter.
This is the conclusion of a study led by UC Riverside astrobiologist Stephen Kane published this week in the Astronomical Journal.
The search for life in outer space is typically focused on what scientists call the “habitable zone,” which is the area around a star in which an orbiting planet could have liquid water oceans—a condition for life as we know it.
Kane had been studying a nearby solar system called Trappist-1, which has three Earth-like planets in its
