Remember the first two exoplanets discovered(1996)? well, now they've discovered one of them looks like a carbon-copy of our own 1,300 light-years away. With the same distance from it's Sun(which is also a twin of our star), same volume and size.
The planet(which was formally detected by gravitation pulse in 1996 as Planet Z) appears to have many lands and oceans(which can only exist in the presence of the elements that make up our world). You can see for yourself at
this location!
