For nearly nine years after its takeoff, the Kepler Space Telescope has been successfully validating approximately 1300 exoplanets only since 2017 using the transit photometry method for exoplanets detection. A new research, however, indicates that the Kepler would not be 100 percent precise in validating exoplanets or may supply “false positives”.
The new study, issued recently in the renowned Astronomical Journal, has shed light on how scientists are examining whether the Kepler Space Telescope has uncovered an exoplanet or not.
As reported in the before-mentioned publication, scientists check the data supplied by the Kepler Space Telescope with a secondary telescope to ascertain and confirm if Kepler has really uncovered an exoplanet once it has recognized a “drop in brightness”. In some cases, the astronomers say, the “drop in brightness” was provoked by a different space object passing by that resulted in the stars light to fade away.
Kepler Space Telescope provided “false positive” readings due to incorrect NASA’s math equations on the transit photometry method for exoplanets detections
The new research actually indicated that errors are more probable at the moment when NASA space agency is articulating the modalities for authenticating exoplanets of the same size as our planet or situated at the same approximate distance to their home star as the distance between us and our Sun.
Kepler discovered the exoplanets in such vast numbers that NASA was not effective in tracing and verifying the authenticity of the data separately. That is why NASA’s astronomers have begun working in a different manner.
As part of the new validation method, the scientists used mathematical equations to examine the authenticity of the findings the Kepler Space Telescope has made. In the view of the scientists who participated in the new study, however, the issue with the use of the new transit photometry method’s math equations for detecting exoplanets is that NASA’s mathematical equations do not address errors and/or incoherencies in the scanning instruments.
Therefore, Kepler Space Telescope may have sent tons of “false positive” readings back to NASA.
