ESO: Media Telecon to Discuss Significant Exoplanet Finding

"On Monday 19 October 2009, astronomers will report at the international ESO/CAUP exoplanet conference in Porto, Portugal, on a significant discovery in the field of exoplanets, obtained with the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO's 3.6-meter telescope."

From the same authors, using the same instrument: arXiv:0906.2780: The HARPS search for southern extra-solar planets XVIII. An Earth-mass planet in the GJ 581 planetary system

"We report here the detection of an additional planet - GJ 581e - with a minimum mass of 1.9 M_earth With a period of 3.15 days, it is the innermost planet of the system and has a 5% transit probability."

President Obama kicked off Astronomy Night on the South Lawn of the White House. Some 150 middle school students from the Washington area got to learn more about their universe using more than 20 telescopes provided by NASA and other organizations. They observed Jupiter, the moon and selected stars. Other activities included science presentations with samples of meteorites and moon rocks. NASA's Museum Alliance, a consortium of museums, science centers and planetariums conducted activities worldwide to coincide with the White House event. Astronomy Night helped note the International Year of Astronomy, a global celebration of contributions to society and culture in the 400 years since Galileo first used a telescope.
