Astronomers find over 100 exoplanets in three months

An international team of astronomers has found more than 100 planets outside the solar system within three months using a combination of space and ground-based telescopes. They investigated 227 exoplanets found during NASA’s K2 mission and confirmed 104 of them. Seven of the confirmed exoplanets were found to have ultra-short orbital periods of less than 24 hours.
