Telfrow, you cheated <img src="/images/icons/shocked.gif" /><br />I can't approve my own images yet <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

Sorry <img src="/images/icons/frown.gif" />...are they the same? <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>

No, no, I was just joking ... <img src="/images/icons/laugh.gif" /> <br />Thanks for posting those great examples of illusion ! <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

<font color="yellow">"A lava dome?...Or Meteor Crater?"</font><br /><br />Great example! I hope it gives pause to those who think they see giant worms or trees in Mars orbiter images. <div class="Discussion_UserSignature"> </div>

I sincerely doubt it will. <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>

Well, at least good examples of such optical illusions will help more reasonable people resist arguments that are based on the proposition that such illusions do not exist. <div class="Discussion_UserSignature"> </div>

Of course, most of the people who see fossils where there aren't any are not falling prey to this particular optical illusion. Paredolia (sp?) is a more common cause of this. (However, this particular optical illusion has led to some claims of lava tubes -- or worm trails -- on other worlds.) <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

<b>Craters, Craters Everywhere</b><br /><br /><i>Craters within craters cover the scarred face of Saturn's moon Rhea in this oblique, high-resolution view of terrain on the moon's western hemisphere. <br /><br />A large, degraded crater lies at the center, filled with rolling mounds and many smaller craters. A couple of linear depressions are visible in the terrain (especially at lower right), possibly marking tectonic faults. The crater is about 90 kilometers-wide (56-miles) and is located at 8.5 degrees south latitude, 154.9 west longitude. The moon's icy regolith, or loose surface material, has likely been pummeled into a fine powder over the eons. <br /><br />This is one of the highest-resolution images of Rhea's surface obtained during Cassini's close flyby on Nov. 26, 2005, during which the spacecraft swooped to within 500 kilometers (310 miles) of the large moon. Rhea is 1,528 kilometers (949 miles) across and is Saturn's second largest moon, after planet-sized Titan. <br /><br />The clear filter image was acquired with the wide-angle camera at an altitude of 620 kilometers (385 miles) above Rhea. Image scale is about 85 meters (280 feet) per pixel. </i><br /><br />http://www.nasa.gov/mission_pages/cassini/multimedia/pia07765.html <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>
