Exomoons are difficult to detect and confirm using current techniques,[3] and to date there have been no confirmed exomoon detections.[4] However, observations from missions such as Kepler have observed a number of candidates.[5][6] Two potential exomoons that may orbit rogue planets have also been detected by microlensing.[7][8] In September 2019, astronomers reported that the observed dimmings of Tabby's Star may have been produced by fragments resulting from the disruption of an orphaned exomoon.[9][10][11] Some exomoons may be potential habitats for extraterrestrial life.[2]
