New Solar System discovered with LIVEABLE climate and a type of alien that looks like a human

A NEW solar system was discovered on May 1, 2021 and there was a planet that looked somewhat like earth but it was flat and it also had one moon. Unfortunately the Astronomer’s name is unknown and no pictures but there seems to be a type of alien floating above the surface with no oxygen tank the Astronomer says it looked aggressive and was about to attack but luckily the robot was able to take an atmosphere test and go.
