Alien Planets Found Around Sun.

For the first time, astronomers have discovered alien planets orbiting sun-like stars located in a crowded star cluster, scientists announced on 14 of September.

The two newfound worlds are Jupiter-like behemoths far too hot to be habitable. But their existence may hearten those searching for life beyond Earth by helping to show that planets can form in a wide range of environments, such as dense clusters, researchers said.

"We are detecting more and more planets that can thrive in diverse and extreme environments like these nearby clusters," Mario Perez, NASA astrophysics program scientist in the Origins of Solar Systems Program, said in a statement. "Our galaxy contains more than 1,000 of these open clusters, which potentially can present the physical conditions for harboring many more of these giant planets."
