An
international team of scientists said on 2 May that they had discovered a trio
of Earth-like planers that are the best-bet so far for finding life outside our
solar system. The three orbit an ultracool dwarf star a mere 39 light years
away, and are likely comparable in size and temperature to Earth and Venus,
they reported in a study.
“This
is the first opportunity to find chemical traces of life outside our solar
system.” said lead author Michael Gillon, an astrophysicist at the University
of Liege in Belgium. All three planets had the “winning combination” of being
similar in size to Earth, “potentially habitable” and close enough so their
atmospheres can analysed with current technology, he said.
