After a couple of weeks filled with rumour and speculation, the much-anticipated latest findings from the Curiosity rover were presented yesterday morning at the American Geophysical Union (AGU) meeting in San Francisco. So, has Curiosity found organics yet or not?
Well, who would have thought? Water ice on Mercury, that scorched little planet closest to the Sun? That’s just what scientists have found, as well as organic material, at Mercury’s north pole, it was announced yesterday.
If you are searching for other inhabited worlds, almost any kind of star may do according to current findings, except perhaps for white dwarfs. As it turns out, planets orbiting these dying stars, as well as brown dwarfs, are probably very poor candidates for life.
