Alien life could be more common than we thought, according to scientists.
But any extraterrestrial life out in the universe is likely to inhabit a very different star system, very far away, the researchers conclude.
The new study looked at a theoretical twin of Earth and explored how it might fit in with a binary star system. Unlike our own solar system, such places have planets that revolve around two stars.
They found out that in 87 per cent of cases, those planets should be tilted similarly to Earth. That in turn is thought to be an ingredient for a climate that favours the birth of complex life, like ourselves or aliens.
