Astronomers using telescopes at ESO's observatories in Chile have discovered three planets around a dim dwarf star just 40 light-years from Earth. These worlds have sizes and temperatures similar to those of Venus and the Earth, and they are the best targets so far found in the hunt for life elsewhere in the Universe.
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, published in Nature. “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 be analysed with current technology, he told AFP.
