| New research shows that stars of varying ages could have profound consequences for the development of emerging life forms. Newly formed stars spin faster than midde-aged stars, generating strong magnetic fields and emitting more intense radiation. This could have a dramatic effect on any life developing is such systems. |

| Astronomers searching for Earthlike planets often focus on the 'habitable zone' around stars – where the heat from the star is at the perfect level for liquid water to exist. New calculations indicate that planets close to their parent stars could experience tidal forces that limit the habitable zone and change the criteria habitable planets. |
