It's unclear who invented the telescope, but it wasn't Galileo.&nbsp; He did, however, refine the technology and was the first to use it for peering at objects beyond the earth.&nbsp; He did this in 1609. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

<p>I believe he built his first telescope in 1609 from a discription written in 1608. He went public in 1610 with his second home built which allowed him a 30X magnification. </p><p>He was not the inventor of the telescope though. His significance in this was from what he did with it. He looked up!</p> <div class="Discussion_UserSignature"> </div>

From the ancestral time the world space research established on blind theory. We although demand that we have discovered lots of mysteries viz. milk ways, galaxies, nebulas, white drafts, black holes etc., in real they are creation of space mirror. SPACE MIRROR is the truth and hidden mystery of the space. Since we are unknown about space mirror, our research has diverted from original truth and we have spent lots of time and money behind the false truth. </font></p><p style="margin:0in0in0pt" class="MsoNormal"><font face="Times New Roman" size="3">Therefore it invites to visit </font><font face="Times New Roman" size="3">http://www.spacemirrormystery.com</font><font face="Times New Roman" size="3"> and for prosperous space research. </font></p><p><span style="font-size:12pt;font-family:'TimesNewRoman'"><br /></span>&nbsp;</p> <div class="Discussion_UserSignature"> <p>pradipta</p> </div>
