		<description>&quot;We know that a number of ancient civilisations were able to predict the positions of the stars and planets with great accuracy, but what about eclipses? It seems to me that predicting the recurrence of eclipses would be pretty difficult without developing a Copernican cosmology, but then again that just might be arrogant 21st Century me looking back with 20/20 hindsight. Were there any ancient civilisations that were able to predict solar and lunar eclipses?&quot;

I&#039;m pretty sure that the ancient Greeks and Chinese were able to predict ecplipses, as well as medieval Muslims and Christians.  Probably some other civilizations could as well - India, the Mayans, etc.

By the late 15th century Europeans had printed almanacs stating when eclipses would occur.  There&#039;s a story that Columbus, who got stranded on Jamaica during his 4th voyage, intimidated the Jamaican natives into providing him and his crew with food by predicting an eclipse of the moon based on an almanac that he was carrying.</description>

		<description>WHAT ABOUT A COMBINED PLANETARY OCCULTATION AND LUNAR ECLIPSE??? The other day I watched as a star popped out from behind the moon on the opposite side from the edge of the moon growing in light as the earth&#039;s shadow left it. Would there be any way to calculate when (past or future) we would have BOTH a planetary occultation and eclipse simultaneously?</description>

		<description>Special relativity &amp; quantum mechanics aren&#039;t alternative (competing) physical theories. Relativity alone can not be made to forecast the results of quantal experiments, not even &quot;awkwardly&quot;. In fact, it&#039;s necessary to unify special relativity into quantum mechanics (Dirac theory) in order to generalize QM. They&#039;re definitely not competing theories; they&#039;re more like partners.</description>

		<description>I don&#039;t get what people think is so mysterious? Yes, Saturn looks big. But then, you&#039;re only seeing a segment of the Moon in that image - so the Moon looks pretty darn huge, too.  We&#039;re seeing an est 45 degree arc segment of the Lunar silhouette, with the center point offset to the bottom of the image.    I see an ~30cm diam Moon with a .5 cm diam Saturn (no rings).  No size disparity apparent to me.

TheBlackCat said:
&gt; What is the time difference between the first and last picture?

I guess you missed the posted *LINK*

&lt;blockquote&gt;A number of shots were taken at 30s intervals (10s movie captures at 60fps, fixed on Saturn) which gave me the positional information I needed to build the composite you see here. The RGB image of Saturn was captured just before the occultation and the lunar limb just after (this is a three frame mosaic). The interval positions shown are separated by 90s in time. South is up in the image and the Moon would be moving towards the upper right. &lt;/blockquote&gt;



Gary Ansorge said:
&gt; Again, Relativity can make many of the calculations needed to explain what we see on a sub-atomic level just as accurately as quantum mechanics, itâ€™s just incredibly akward and time consuming.

Uh, I don&#039;t think they deal with the same aspects of physics. Got something I can read on that?</description>

		<description>BMurray,

You&#039;re right that were you to travel the 1/4-million miles to the Moon the percent change in your distance to Saturn would be too small to be important. But the telescope doesn&#039;t simulate a translation through space. It magnifies everything in its field of view by the same factor. It increases their angular diameters. So, given that to the naked eye on Earth the Moon occupies an angle of about 1/2 degree, and Saturn occupies an angle so small that it appears as only a bright spot, if the telescope magnifies Saturn&#039;s angular size enough to resolve into a disc with rings, then the Moon magnified by the same factor will assume a positively huge angle, as it does in the above photo.</description>

		<description>I don&#039;t understand why Saturn would appear to be interestingly bigger seen from near the moon than it appears from earth.  It should be only trivially closer in the best case.  Is this an artifact of the way magnification works with this telescope, in that the relative sizes are not actually the same as if I was that apparent distance from the moon?</description>

		<description>Hey, Nanny Filters are an &lt;i&gt;endless&lt;/i&gt; source of amusement. 8-)

I&#039;ve been blocked from a page on a news site because it discussed gays!  The headline was something like &quot;IBM tops poll of best places to work if you&#039;re gay.&quot;

A friend of mine once tried to warn her other friends about the infamous &quot;Melissa&quot; virus, only to have her warning blocked because it contained the word &quot;virus&quot; in it!

But apart from mis-identifying the BA (as well as potentially a lot of medical sites, as &quot;occult&quot; is also used in medical jargon), the religious arrogance of that ISP is staggering.

Oh!  I just got your pun!  (I&#039;m a bit slow.:-))</description>

<p>Uh, I think that&#8217;s &#8220;selenology.&#8221; They&#8217;d have to wait until they got back to do &#8220;geology.&#8221;</p>

		<description>Hi Rosemary,

While on the Moon the astronauts&#039; principle agenda was geology, for study of the Moon itself. That&#039;s the one thing which they could do better on the lunar surface than anything else. The Moon isn&#039;t significantly closer or farther from the other planets than is Earth, so Earthbound astronomers, with their large telescopes, were in a better position for planetary observations than the Apollo crews.</description>

		<description>Eclipses can be predicted w/o Copernican cosmology, but it&#039;s REALLY, REALLY difficult, which is one reason the heliocentric theory caught on, because it explained what we were seeing and allowed us to calculate the positions of planets, etc, much more easily. I&#039;ve always thought the main reason we progress is because we&#039;re basically lazy,,,well, I am,,,

Again, Relativity can make many of the calculations needed to explain what we see on a sub-atomic level just as accurately as quantum mechanics, it&#039;s just incredibly akward and time consuming.

So, we look for theories that are more &quot;elegant&quot; in their application, ie, beautiful in their simplicity, and easy to use,,,


Yeah, we&#039;re definetly lazy,,,but, ya know, whatever works,,

		<description>Actually, all the eclipse talk lately brings up a point that might be interesting for a Q&amp;BA. We know that a number of ancient civilisations were able to predict the positions of the stars and planets with great accuracy, but what about eclipses? It seems to me that predicting the recurrence of eclipses would be pretty difficult without developing a Copernican cosmology, but then again that just might be arrogant 21st Century me looking back with 20/20 hindsight. Were there any ancient civilisations that were able to predict solar and lunar eclipses?</description>

		<description>There was a similar series shown in National Geographic (1974 maybe?) Full occultation though.  Possibly elsewhere. I did cut it out and made a flip book of it.  That is much cooler.  I&#039;m glad there are hobbiest out there to bring it home!</description>

		<description>Anyone know how many grazing occultations involving moon/planet there have been since, um, when we can start counting?</description>

		<description>&quot;The Moon passed in front of Saturn as seen from England the other day, and Peter was on it. &quot;

So much for the moon hoaxies&#039; (hoaxers?) claim man hasn&#039;t returned to moon for decades.</description>
