Posted on 09/03/2012 12:23:54 PM PDT by SunkenCiv
Explanation: Perhaps the most famous star cluster on the sky, the Pleiades can be seen without binoculars from even the depths of a light-polluted city. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and closest open clusters. The Pleiades contains over 3000 stars, is about 400 light years away, and only 13 light years across. Quite evident in the above photograph are the blue reflection nebulae that surround the brighter cluster stars. Low mass, faint, brown dwarfs have also been found in the Pleiades. (Editors' note: The prominent diffraction spikes are caused by the telescope itself and may be either distracting or provide aesthetic enhancement, depending on your point of view.)

M45 is about seven miles from here.
Always a crowd pleaser.
The Subaru logo.
Yep. Subaru is Japanese for The Pleiades.
Had one, hope to have one again some day. Great little car.
Why do you think it’s 400 light years away?
The Pleiades is a good object to illustrate an anomaly of our vision. Our eyes cannot collect the most light when looking straight ahead, but when looking slightly to the side. You might be able to see a certain number of stars in the Pleiades (perhaps 5 to 8) on a clear night when looking straight at it, but you might be able to see another star or two when you look slightly to the side and catch it “out of the corner of your eye”, so to speak. Try it. It works.
God to Job: “Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion?” (Job 38:31)
“The heavens declare the glory of God, and the firmament shows His handiwork.” (Psalm 19:1)
God, the awesome creator!
Because it takes 400 years to get all that dark out of the way.
Like my girls said, “Oooohhhh, sparkly!” Beautiful, Sunky.
That’s where the greys are from. Or so they say.
The phenomena that you describe is due to the structure of the human eye. Basically the receptors in the eyes are cells that are rod shaped and cone shaped. The cones are in the center and the rods at the edge. You use the cones in good light and the rods in poor light conditions.
To illustrate this, toss a ball into the air in poor light, after dusk. If you try to look directly at the ball, you will not catch it. Look to the side and you, using the rods, will see it more clearly and be able to catch it!
ask any of your atheist friends if they think that this just “happened”?????
I love that segment of the heavens!
Galileo published this diagram of his observation of the Pleiades. I can find corrrespondence of most of the lesser stars to a modern photograph, but their spatial relation is quite distorted. This is because the field of view of his telescope was so small that he had to mentally stitch the scene together. Even with this allowance, I find the three stars at the top under "CONSTELLATIO" problematical to identify.
:’) Some of ‘em, anyway.
If you want to question the revealed word of God, that’s your business.
In the meantime I’ll LOL at your 400 million year “theory”.
They may have faded since his time. There are known dark stars in the cluster. :’)
You’re completely off your rocker.
Shove it up your keister.
It's got "just happened" written all over it. That is, it has every appearance of having evolved according to natural law, and there are many other globular and open clusters which show various stages of this evolution and other differences which depend on natural circumstance.
I have no problem at all with them evolving naturally over the eons.....where were they the day before they started to "evolve"....did they just suddenly appear out of nowhere for no reason....I can't dig up enough faith to believe that.
oh good...finally an educated, scientific response to an actual question. At least you point out your interests in your spare time.....voted for Obama too, didn't you???
I sure wish I could read minds as you do. But then again, I’m not a presumptuous ass.
Put this one on “ignore,” my dear Mr. Civilizations.
if anyone in the world can figure out what this drivel means....please advise!!!
I think you have the wrong idea about stellar evolution. This study includes well founded theories on the birth of various types of stars, for example in the famous Hubble image of the Eagle Nebula. The Pleiades are "young hot stars" at ~100 million years old, dating their birth to the age of the dinosaurs on earth. Isn't that something. I never knew it!
And you’re incapable of reading comprehension and self examination after being criticized for your unwarranted rudeness to our very popular thread host.
Awful to be you.
I am never rude to anyone...I merely asked a question....if you can't answer it then so be it.......one day before these magnificant stars appeared....where were they? but lets go back a few years before that....what, if anything, existed ten minutes before the first "thing" appeared anywhere????? In my never to be humble opinion, nothing existed except God . God then created EVERYTHING. It didn't just happen, it was created.
The same may be said of snowflakes. In fact, stars are very much in the nature of snowflakes from a cosmic perspective. If you want to say, "The Lord God made them all," I won't quibble.
I might quibble, though, over the time scale. If you were privileged to witness the formation of the stars in the Pleiades, you wouldn't see much happening day by day. I suppose 10,000 years might make a good frame step, corresponding to some fraction of a second in the formation of a snowflake.
