In two new papers, scientists using Kepler spacecraft data announced the confirmation of 41 more exoplanets in 27 star systems. That brings the total number of confirmed exoplanets to nearly 800.
A huge shift has occurred in the past two decades. Before that, we knew of nine planets in the cosmos. Now, there are eight planets in the Solar System-- Pluto having been demoted to dwarf planet status-- a hundred times that number confirmed in other star systems, and thousands more awaiting confirmation. It's remarkable.
