Kepler 438b is one of the most Earth-like planets yet discovered.
It circulates its sun every 35 days, the sky is red, and its likely to be rocky and hot – but there might be life there. And it’s only 470 light-years away!
We keep wondering whether there is life on other planets but pay rather too little attention to life on our own. What sort of species is it that is responsible for wiping out so many of the fellow inhabitants of this one?
Earth, the most beautiful and life-filled place we know – why are we vandalising it?
PS If it is 470 light years away then the radiation we are ‘seeing’ was emitted in 1545. What were you doing in 1545? Earth was rather different then, wasn’t it? Apart from a bit of fighting there didn’t seem to be much happening. 1544 was quite an interesting year – rats arrived in North America.
