Kepler:The Search for Earth-Size Planets Begins

Since its launch in March, 2009, the Kepler Mission has announced the discovery of 9 confirmed exoplanets (or planets outside our solar system). This video explores how the team works to combine photometry from the spacecraft, data from ground-based observatories and precise asteroseismic analysis to determine if Earths are common or rare in our Galaxy.

MPL3D Solar System - Star sounds

This video shows a computer emulation of stellar seismology in different stars. The surface of a star usually oscillates, and this oscillation can be tranformed into an audible sound wave. Stellar seismology is the study of the propagation of these wave oscillations in the stars, particularly acoustic pressure waves. Star pressure waves are generated in the convection zone near the surface, then the acoustic waves are transmitted to the outer photosphere of the star. The oscillations are detectable on images of the Sun, or by measuring the doppler shift of photospheric absorption lines of a star.

Kepler Mission

In addition to its search for extrasolar planets, the NASA Kepler Mission is studying stars like our own Sun through observations of gentle oscillations of the stars, the field of asteroseismology. These oscillations are the visible manifestation of sound waves trapped in the stellar interiors. The video shows sound waves trapped in the interior of one such star, with an orbiting planet in the foreground. Kepler has observed oscillations in more than 500 solar-type stars, and the background stars represent this ensemble.

Real Star Wars Planet just like Tatooine with 2 suns

NEW YORK - The 1977 movie Star Wars featured a planet with two suns called Tatooine. Now scientists said they have found the first real two-sun planet 200 light years away from Earth. "After 35 years, science fiction has finally become reality," said Mr Alan Boss, a theoretical astrophysicist at the Carnegie Institution for Science in Washington and an author of the study on the planet released on Thursday by the journal Science. The new planet, called Kepler-16b, is about the size and mass of Saturn, and moves in a circular orbit 65 million miles from its suns. Unlike Tatooine, Kepler-16b is far too cold to support life, with temperatures about 100 degrees centigrade lower than Earth, Mr Boss said. The Kepler-16b planet's two suns are different sizes, with the larger one glowing orange and the smaller sun a more reddish colour. Some days the two suns rise and set simultaneously, while at other times they rise or set a couple of hours apart. While some double-star systems, of which there are billions in the galaxy, have been suspected to harbour planets, those smaller bodies have never been seen. Beyond the wow factor, astronomers said the discovery - as so many discoveries of so-called exoplanets have done - had thrown a wrench into another well-received theory of how planets can and cannot form. "In other words," said Ms Sara Seager, a planetary expert at the Massachusetts Institute of Technology who was not part of the discovery team, "people don't really know how to form this planet". It was long thought, Ms Seager said, that for its orbit to be stable, a planet belonging to two stars at once would have to be at least seven times as far from the stars as the stars were from each other. According to that, Kepler-16b would have to be twice as far out as it is to survive. "This planet broke the rule," she said. todayonline
