Hi, Jon...thanks for your response. My Hoagland bio post in the 1st Iapetus segment did not garner even ONE response. <br />You said, "Many amateur astronomers are highly skilled individuals who make major contributions in science but have no formal qualifications." And how true this is. Just as many have also been scorned and ridiculed at their observations. Remember the Hale-Bopp "companion" flap? <img src="/images/icons/smile.gif" /><br />You said, further, "John Lewis published papers in 1971 and 1976 on the possibility of an ocean on Europa. These papers have been widely cited and were written 4 and 9 years before Hoagland's article in a popular science magazine" I am apt to believe you, but since you were so insistent on my info, might you, too, wish to supply our members here the name and date of this peer-reviewed document? If not, that's fine.<br />And then you said, "this discussion of Hoagland's "qualifications" is proving to be something of a diversion" Well, thank GOD for common ground! <img src="/images/icons/smile.gif" /> We certainly agree on that point. I was wondering why you insisted on having Richard's peer-reviewed resume. Why you insisted on this, close to a dozen times! "Diversion" or "distraction", whatever the word, it has become dejour in this "demon-haunted" thread! <img src="/images/icons/smile.gif" /><br /><br />And if NASA provides us new images of Iapetus, as they did on January 1st, and "amatures" or others make observations about the bizarre annomalies seen therein, and postulate ANY reasoned theories about the origin of said strangeness, then it is our job as "space enthusiasts" to be enthused, I suppose. And we SHOULD "stick to the point" which is NOT "whether there is any evidence for artificiality in images of Iapetus", but in fact, is there enough ENTHUSIASM to INVESTIGATE this newest data and gather up even more data to confirm or deny the new hypothesis. Anybody see the RADAR taken of Iapetus on January 1st? <div class="Discussion_UserSignature"> </div>
