Civil Geeks: Exoplanetpalooza
Astronomers in Hawaii play a critical role in the search for planets orbiting stars beyond our own solar system. My latest “Civil Geeks” column explores a recent sky survey that identified over 100 new exoplanets.
Although the existence of alien life will be hard to prove, it’s becoming increasingly probable.

“Now we know the answer, and they are more common than I think most astronomers expected,” he said.
