Astronomers discover second-closest know exoplanet
The School of Arts and Sciences’ Cullen Blake weighed in on the identification of an earth-like exoplanet called Barnard’s Star b. Blake said that while the data used to locate it may be muddied by nearby stellar activity, the exoplanet has been observed enough times to be a strong planetary candidate.
