Mark Twain: _Following the Equator_ Page 27

<<We are moving steadily southward-getting further and further down under the projecting paunch of the globe. Yesterday evening we saw the Big Dipper and the north star sink below the horizon and disappear from our world. No, not "we," but they. They saw it--somebody saw it--and told me about it. But it is no matter, I was not caring for those things, I am tired of them, any way. I think they are well enough, but one doesn't want them always hanging around. My interest was all in the Southern Cross. I had never seen that. I had heard about it all my life, and it was but natural that I should be burning to see it. No other constellation makes so much talk. I had nothing against the Big Dipper-- and naturally couldn't have anything against it, since it is a citizen of our own sky, and the property of the United States--but I did want it to move out of the way and give this foreigner a chance. Judging by the size of the talk which the Southern Cross had made, I supposed it would need a sky all to itself.

But that was a mistake. We saw the Cross to-night, and it is not large. Not large, and not strikingly bright. But it was low down toward the horizon, and it may improve when it gets up higher in the sky. It is ingeniously named, for it looks just as a cross would look if it looked like something else. But that description does not describe; it is too vague, too general, too indefinite. It does after a fashion suggest a cross across that is out of repair--or out of drawing; not correctly shaped. It is long, with a short cross-bar, and the cross-bar is canted out of the straight line.

---

It consists of four large stars and one little one. The little one is out of line and further damages the shape. It should have been placed at the intersection of the stem and the cross-bar. If you do not draw an imaginary line from star to star it does not suggest a cross--nor anything in particular.

One must ignore the little star, and leave it out of the combination--it confuses everything. If you leave it out, then you can make out of the four stars a sort of cross--out of true; or a sort of kite--out of true; or a sort of coffin-out of true.

Constellations have always been troublesome things to name. If you give one of them a fanciful name, it will always refuse to live up to it; it will always persist in not resembling the thing it has been named for. Ultimately, to satisfy the public, the fanciful name has to be discarded for a common-sense one, a manifestly descriptive one. The Great Bear remained the Great Bear--and unrecognizable as such--for thousands of years; and people complained about it all the time, and quite properly; but as soon as it became the property of the United States, Congress changed it to the Big Dipper, and now every body is satisfied, and there is no more talk about riots. I would not change the Southern Cross to the Southern Coffin, I would change it to the Southern Kite; for up there in the general emptiness is the proper home of a kite, but not for coffins and crosses and dippers. In a little while, now--I cannot tell exactly how long it will be--the globe will belong to the English- speaking race; and of course the skies also. Then the constellations will be re-organized, and polished up, and re-named--the most of them "Victoria," I reckon, but this one will sail thereafter as the Southern Kite, or go out of business.>>

I think you more or less gave us the answer yourself - you must search for patterns to discover them. Human beings are very good at seeing patterns, and in fact, we are so good at it that we sometimes see patterns where there are none.

You are watching a specific photo. It could be that another photo, with a higher resolution, would show you that the pattern isn't really there. Many photographs "enhance" the brightness of stars of certain magnitudes, while "suppressing" stars of other magnitudes, making false patterns appear.

Here is another picture of the same patch of the sky. Do you see the same patterns here?

It is possible - possible, mind you - that we are seeing long lines of stars that formed along a shock front of some sort in the Carina Nebula. But we can't say that for certain unless we know the distances to the stars in the apparent lines. It could well be that some are foreground stars and other background stars, in which case the apparent "lines" become illusions.

Why would it? We already get a good look at the asteroid belt, which is lit more brightly by the Sun by many orders of magnitude than any nearby supernova will manage.

A normal Type Ia supernova is ~5 billion (~71,000²) times brighter than the Sun and thus would appear as bright as the Sun if it were ~71,000 times as far away. Since light-year is ~63,000 AU, an Ia supernova would have to be about a light-year away to be brighter than the Sun for us (or about 7 light-years away to be brighter than the Sun for a Kuiper Belt object).

He has an IQ of 197 – it was 199 before he sustained a concussion during the collapse of Springfield's brief intellectual junta – and is a member of the Springfield chapter of Mensa. Frink is generally very polite and friendly. He has a trademark mannerism of using Jerry Lewis-style gibberish when excited, such as "HOYVIN-GLAVIN!" and "FLAVIN" and impulsively shouting other words that have no relevance to the situation at hand. He also occasionally refers to the importance of remembering to "carry the one" in various mathematical calculations. When he rambles he often speaks incoherently in run-on sentences without pauses. Frink also has a tendency to over-complicate simple matters and/or invent scientific terminology while expressing various concepts, e.g. "Father and I got along like positrons and antineutrinos!" or, "microcalifragilistics".>>

<<Taurus Poniatovii (Latin for Poniatowski's bull) was a constellation created by Marcin Odlanicki Poczobutt in 1777 to honor Stanislaus Poniatowski, king of Poland. It consisted of stars that are today considered part of Ophiuchus and Aquila. It is no longer in use. It was wedged in between Ophiuchus, Aquila and Serpens Cauda.

The stars were picked for the resemblance of their arrangement to the Hyades group which form the "head" of Taurus. Before the definition of Taurus Poniatovii, some of these had been part of the obsolete constellation River Tigris.

The brightest of these stars is 72 Oph (3.7 magnitude) in the "horn" of Taurus Poniatovii. The "face" of Taurus Poniatovii is formed by 67 Oph (4.0), 68 Oph (4.4) and 70 Oph (4.0). The five brightest stars belong to loose open cluster Collinder 359 or Melotte 186. Barnard's star is also inside the boundaries of this former constellation. Some minor stars (5th and 6th magnitude) now in Aquila formed the "rear" of Taurus Poniatovii.>>
