John Batchelor and I welcomed Dr. Jeff Coughlin to discuss the recent announcements about the false positives for finding exoplanets regarding the Kepler mission. False positives for identifying exoplanets regarding large bodies is upwards of 52%. Our guest discussed why this was so and why the discovery of the false positive rate for large objects was not a big surprise. False positives for smaller exoplanets is not nearly as high as for the large bodies. Dr. Coughlin talked about the process used to confirm that an object is an exoplanet rather than something else. The process involves the use of ground based observations, the study of brightness of the object, and much more. He talked about how the James Webb Space Telescope will make it easier to detect exoplanets from something else though the use of Hubble is not that applicable given how hard it is to get time on Hubble and the cost of using Hubble. Dr. Coughlin suggested that finding an Earth-like exoplanet with an oxygen and nitrogen atmosphere is certainly possible within “our” lifetime and he said he was optimistic about finding such a discovery.
