A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

The wonders of life on Earth are endless, but all that may never have come to pass were it not for the planet having the perfect amount of oxygen at birth.
