Scientists using a powerful telescope in Chile have found an alien planet circling a star that is nearly identical to the sun and located in a star cluster 2,500 light-years from Earth. The discovery marks the first time that scientists have found an exoplanet circling a solar twin in a star cluster, according to European Southern Observatory officials, the group that operates the telescope instrument that made the discovery. Scientists used ESO’s HARPS telescope instrument to find the exoplanet, which is a little smaller than Jupiter and takes seven days to orbit its star. The strange world, along with two other exoplanets also found by the HARPS instrument, are located in Messier 67, a star cluster populated by about 500 stars.
