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.
