00:09an earth-like world is only the beginning scientists believe a solar system like ours
00:15with its particular makeup of planets and other rocky bodies is also vitally important science
00:21alert reports the discovery of a pair of worlds around a star eerily similar to our own sun
00:28could be the closest we've come to finding such a system even if it's 175 light years away

01:34ingredients essential for life the findings submitted to the monthly notices of the royal astronomical
