I just finishe...Hello,<br /><br />Sorry if this is off-topic. I just finished reading your book, I&#39;ve thoroughly enjoyed it. Reading about the transition to the digital astronomy was very interesting for me. I remember reading James Herriot&#39;s books a long time ago, I was similarly fascinated by his description of the many major transitions going on in his profession (okay, now this is definitely off-topic). I&#39;m going to remember the part about the sign language for infants -- for the future, just in case.<br /><br />I couldn&#39;t help wondering about a couple of things. One is when you mention that the coordinates of Xena and Easterbunny were found by someone else as well and sent to &quot;the place where you announce discoveries&quot;. Does that mean that it was sent anonymously? Because if it was sent by the same Spanish team, I think nobody would be able to argue a coincidence. Also, does it mean that if the authorities had formally followed the protocol, the guys who sent the announcement would have been recognized (at least initially) as the discoverers of Xena and Easterbunny?<br /><br />The second thing is that I couldn&#39;t help thinking that maybe it would have been possible to use more advanced methods than flipping between two images to detect the differences. Morphological image processing was well developed at that time already, so wouldn&#39;t it make sense to, say, find morphological components in the image and discard the artifacts based on their shape measurements?<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9094742788006644220.post-26415776783186809872015-10-16T11_28_28.576-07_002015-10-16T11_28_28.576-07_00The old algorithm doesn&#39;t exist anymore, I sus...The old algorithm doesn&#39;t exist anymore, I suspect.

A probe to Eris, or any of the other ...Yes, indeed. A probe to Eris, or any of the other trans-Plutonian &quot;planets&quot; would be great. Of course, it&#39;s slightly impossible just now, as we have no easy way to get to space as we used to with the Shuttle. But if we had a way to put a probe in Earth orbit, then a relatively cheap ion engine could push the probe out to wherever. It might take a decade or two, of course.<br /><br />Now if any of the &quot;warp drives&quot; in the news recently could actually work (not holding my breath, but still...) then even if we could only get to half the speed of light, the trip would take days, not decades; and even a maned excursion becomes possible if not plausible. I think Dr. Miguel Alcubierre&#39;s work shows the most promise. (See Wikipedia, of course...) While it might not offer FTL speeds, chugging along at half the speed of light would be just fine for exploring the Solar System.Reggiehttps://www.blogger.com/profile/17478546089651522517noreply@blogger.comtag:blogger.com,1999:blog-9094742788006644220.post-48939328340146995832015-05-11T21_56_32.873-07_002015-05-11T21_56_32.873-07_00Could Eris be worth sending a mission near?

Even NASA didn&#39;t have much information on it. I understand it is not likely ever going to happen, but it would be good to expand our knowledge of our solar system by going to one of the farthest objects in our solar system. If I am correct, It&#39;s orbit goes to the very edge or beyond the Kuiper Belt. It would certainly be a better idea to send a mission to Eris than other places, Eris is the most unique. The data could also be compared to that of Pluto, who is said to be it&#39;s &quot;twin&quot;.
