                    9, 2008:</STRONG> A gigantic telescope on the Moon has been 
                    a dream of astronomers since the dawn of the space age. A 
                    lunar telescope the same size as Hubble (2.4 meters across) 
                    would be a major astronomical research tool. One as big as 
                    the largest telescope on Earth—10.4 meters across—would see 
                    far more than any Earth-based telescope because the Moon has 
                    no atmosphere. But why stop there? In the Moon's weak gravity, 
                    it might be possible to build a telescope with a mirror as 
                    large as 50 meters across, half the length of a football field—big 
                    enough to analyze the chemistry on planets around other stars 
                    for signs of life.</FONT></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://science.nasa.gov/headlines/y2008/09jul_moonscope.htm"><FONT face="Verdana, Arial, Helvetica, sans-serif" size="2"><A href="http://science.nasa.gov/headlines/y2008/images/moonscope/lunartelescope_big.jpg"><IMG hspace="10" height="225" border="1" align="right" width="268" alt="see caption" src="http://science.nasa.gov/headlines/y2008/images/moonscope/lunartelescope_med2.jpg" /></A>That's 
                    the dream of Peter C. Chen, astrophysicist at NASA Goddard 
                    Space Flight Center. And he wants to build it using lunar 
                    dust—because that might just be the most economical approach.</FONT></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://science.nasa.gov/headlines/y2008/09jul_moonscope.htm"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/science.nasa.gov/img/DF8297DD-AA63-41EB-BC90-50D86710CF3C" alt="see caption" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/93ED28DF-050F-4A9A-BC04-D8F4A5BBB158/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
