NASA’s Kepler Mission Discovers a World Orbiting Two Stars
The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA's Kepler mission has made the first unambiguous detection of a circumbinary planet -- a planet orbiting two stars -- 200 light-years from Earth.
The turbulent lives of stars
The stars are boiling! The reason is the energy generated in the center of the star that wants to escape. If this does not happen quickly enough, the star starts to ‘boil’ in the outer layers causing vibrations that result in light variations, like in the Sun. Such oscillations have now been discovered by Victoria Antoci and collaborators using the NASA spacecraft Kepler, but in a much hotter star. The scientists publish this in the most recent issue of “Nature”.

Of those, 408 reside in systems containing two or more planets, and most of those look very different than our solar system. David Latham of the Harvard-Smithsonian Center for Astrophysics presented findings today in a press conference at the 218th meeting of the American Astronomical Society.
How to Learn a Star’s True Age
For many movie stars, their age is a well-kept secret. The same is true of stars in space. Like our Sun, most stars look almost the same for most of their lives. So how can we tell if a star is one billion or 10 billion years old? Astronomers may have found a solution – measuring the star’s spin. Søren Meibom of the Harvard-Smithsonian Center for Astrophysics presented findings today in a press conference at the 218th meeting of the American Astronomical Society.
Kepler discovery of a unique triply eclipsing triple star
Star HD 181068 , a 7th magnitude star almost visible to the naked eye is in reality a complex triple system in which three stars undergo mutual eclipses as each of the stars gets behind or in front of the others. The most luminous object is a red giant star around which a close pair of two red dwarfs orbits with a period of 45.5 days. The combined light from the three stars show sharp brightness decreases with a period of 0.9 days produced by the mutual eclipses of the close pair of dwarfs, while it takes 2 days for the close pair to pass in front of or behind the red giant.
