Well-known exoplanet researcher Michel Mayor announced on 21 April 2009 the discovery of the lightest exoplanet found so far. The planet, "e", in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist. These amazing discoveries are the outcome of more than four years of observations using the most successful low-mass-exoplanet hunter in the world, the HARPS spectrograph attached to the 3.6-metre ESO telescope at La Silla, Chile.

You need to provide a much smaller video window, this just will not play!!!!

@Chris: It play very good for me! Perhaps something wrong with your graphics settings or slow internet connection.

@portal team: Very nice website!!! I think, I will look in here every day. Is this only in 2009?

@Chris: Above is a HD video which may be very heavy for your computer - also we're linking directly to providers of the content, so above is not served from the PTTU servers.

@Marc: We hope very much it continues beyond 2009, but naturally depends on community involvement.

Cheers,
Holm (Development Lead on PTTU)

Great video - paused it and went to work - watched it once it had downloaded. Very interesting, and I concur nice site. Sounds like a cool place to visit - nice that they are large exoplanets - when is EOS perfecting wormhole travel so that we can get there to check it out???? :-)
