It would seem we are not alone.
And while we are not quite ready for something like Star Trek’s
United Federation of Planets, the almost daily discovery of new planets
has brought the number of known worlds to well over 450.
Some of these worlds exhibit characteristics that have scientists
scratching their heads. Eccentric orbits, wild temperature extremes,
multiple suns and super-Earths that could potentially harbor life, are
just a few of the surprising finds by researchers. What will we see when
we arrive at these planets? And when will that happen?
