 A new laser system should make it possible to detect potentially habitable Earth-like planets for the first time by watching for their effects on the light produced by the stars they orbit.</p> <P>Researchers at the Harvard-Smithsonian Center for Astrophysics have adapted a relatively young laser technology to discern the once undetectably faint gravitational influence a rocky, Earth-like planet revolving around a Sun-like star exerts on their home stars' light output.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/04/harvard-center.html">If the Harvard technique holds up in use on actual telescopes, it could
be "a huge breakthrough" in the search for Earth-like planets, which
will help scientists "understand how our own Earth came to be" and
search for life beyond our planet, says Sara Seager, a professor of
earth and planetary sciences at MIT in an interview with the MIT Technology Review.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/04/harvard-center.html"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/www.dailygalaxy.com/img/67B38E40-998F-4319-B1CF-9EC5FED5E1DD" alt="Laser_x220_2" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/04/harvard-center.html">To date, astronomers have discovered nearly 300 exoplanets, outside
