Stars nearly as old as Sun found to have similar spin rates

Astrophysicists from Germany and America have for the first time measured the rotation periods of stars in a cluster nearly as old as the Sun. It turns out that these stars spin once in about twenty-six days — just like our Sun. This discovery significantly strengthens what is known as the solar-stellar connection, a fundamental principle that guides much of modern solar and stellar astrophysics.

Kepler finds tenth transiting ‘Tatooine’ exoplanet

Astronomers have discovered the tenth known ‘transiting circumbinary’ planet, which orbits two stars. Like the fictional planet “Tatooine” from Star Wars, this planet has two suns in its sky. Known as Kepler-453 b, the new planet is a gas-giant six times the diameter of Earth and lies in the habitable zone of its host pair of stars.
