Astronomers have discovered a planet only 20 light-years away which some say has a "100 per cent chance" of having life.

Read it, and you do a double-take, though. It's only 14 million miles from its sun?? 😮 (We are 93 million.) Three times the mass (hence gravity) of Earth? And most boils as it faces its sun. Yeah, a "new Earth" I could do without visiting - and more arrogance from scientists with this "100 per cent" certainty.
