More planets could be homes for aliens than we thought, scientists say

There might be many more planets that could be home to aliens than we thought, according to a new study.

For years, scientists have searched for life in the “habitable” or “goldilocks” zone – where it is neither too hot or too cold to have liquid water. Those worlds have been the centre of our search for alien life, since we believe that liquid water is necessary to make a planet habitable.
