NASA announced on Wednesday that seven Earth-sized planets have been
spotted around a small star in the Aquarius constellation. Michaël
Gillon, an astrophysicist at the University of Liège in Belgium, said
the star is "so small and cold that the seven planets are temperate,
which means that they could have some liquid water and maybe life, by
extension, on the surface." The discovery marks the first time that so
many planets close to Earth's size have been found in orbit around the
same star, called Trappist-1. Scientists have said the news brings new
hope that the Milky Way may resemble our own home and even could spur on
the hunt for alien life. |
