ESO releases ESOcast 18: Exoplanet Caught on the Move

The astronomy podcast featuring news and cutting edge science from ESO

10 Giugno 2010

For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves from one side of its host star to the other. The planet has the smallest orbit so far of all directly imaged exoplanets, lying almost as close to its parent star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. Because the star is so young, this discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms.

Together with the press release describing this discovery made with ESO’s Very Large Telescope, ESO has issued a new video podcast, ESOcast 18, entitled “Exoplanet Caught on the Move”, with our host, Dr J. The ESOCast provides a nice explanation of the discovery and its importance, and contains also several beautiful artist’s impressions.

The video is available in various formats, including HD, and can be watched or downloaded, also directly from iTunes.
