The bubble nebula; I've seen a lot of pictures of nebulae that resemble earthly matter, but this one I find unique as well. This is one of the smallest nebulae that I have discovered, only ten light years in diameter. Small in comparison to many other nebulae that have been discovered over the years. That O-type star within the bubble is another interesting feature.

Personally, I think his conversation is just as likely to fly off at a tangent. :mrgreen:

M.L. Weems — The Life of Gen. Francis Marion. 1801 "But in reaching the ground where we had left him encamped, we got advice that he too, with all his troops, were gone off, at a tangent, as hard as he could drive."

James Fenimore Cooper — The Monikins. 1820 "This person was a Tangent, who had a besetting wish to become a Riddle, although the leaning of our house was decidedly Horizontal; and, as a matter of course, he took the Riddle side of this question."

Jack London — Michael, Brother of Jerry. 1896 "The mate obeyed, although he kept an anxious eye on the whale, which had gone off at a tangent and was smoking away to the eastward."

I daresay you`ve quite come to the conclusion by this time that Cullingworth is simply an interesting pathological study--a man in the first stage of lunacy or general paralysis. You might not be so sure about it if you were in close contact with him. He justifies his wildest flights by what he does. It sounds grotesque when put down in black and white; but then it would have sounded equally grotesque a year ago if he had said that he would build up a huge practice in a twelvemonth. Now we see that he has done it. His possibilities are immense. He has such huge energy at the back of his fertility of invention. I am afraid, on thinking over all that I have written to you, that I may have given you a false impression of the man by dwelling too much on those incidents in which he has shown the strange and violent side of his character, and omitting the stretches between where his wisdom and judgment have had a chance. His conversation when he does not fly off at a tangent is full of pith and idea. "The greatest monument ever erected to Napoleon Buonaparte was the British National debt," said he yesterday. Again, "We must never forget that the principal export of Great Britain to the United States IS the United States."

A ten light-year diameter space bubble for a little space girl seems disproportionate. Would a little earth girl even notice a ten ly diameter bubble at her wedding?? Just doesn’t sit right with me. Maybe that space girl isn’t so little. Or maybe she’s little on a bigger scale. Something’s got to give here. I’m straining but I have to be careful… too much pie for lunch.

It's a cosmic warning :: be careful when you take one tangerine to make a pie - even consuming a quarter of it can give you 1 helluva of a case of space bubbles .....

Naw! I figured since they blew soap bubbles after weddings at the bride and groom; after all, it is a space bubble. :)

<<In 1958, Jesse Lee Turner released the single "Little Space Girl" on Carlton Records; the tune hit #20 on the Billboard Hot 100 in 1959. The follow-up "Thinkin'" failed to chart, and Turner switched to Top Rank Records to release "Do I Worry". The record was promoted poorly and sold poorly. Moving to Sudden Records, he wrote and issued "Ballad of Billy SOL Estes." Turner is now an evangelist who sings rock´n´roll songs with Christian lyrics. On his homepage he tells the story of his bad luck in becoming a star.>>

http://en.wikipedia.org/wiki/Crystal_skull wrote: <<The crystal skulls are a number of human skull hardstone carvings made from clear or milky quartz rock, known in art history as "rock crystal", claimed to be pre-Columbian Mesoamerican artifacts by their alleged finders. However, none of the specimens made available for scientific study have been authenticated as pre-Columbian in origin. The results of these studies demonstrated that those examined were manufactured in the mid-19th century or later, almost certainly in Europe. Despite some claims presented in an assortment of popularizing literature, legends of crystal skulls with mystical powers do not figure in genuine Mesoamerican or other Native American mythologies and spiritual accounts.

Some believers in the paranormal claim that crystal skulls can produce a variety of miracles. In the 1931 play The Satin Slipper, by Paul Claudel, King Philip II of Spain uses "a death's head made from a single piece of rock crystal," lit by "a ray of the setting sun," to see the defeat of his Armada in its attack on England. Another novel and historically unfounded speculation ties in the legend of the crystal skulls with the completion of the current Maya calendar b'ak'tun-cycle on December 21, 2012, claiming the re-uniting of the thirteen mystical skulls will forestall a catastrophe allegedly predicted or implied by the ending of this calendar. An airing of this claim appeared in The Mystery of the Crystal Skulls, a 2008 program produced for the Sci Fi Channel in May and shown on Discovery Channel Canada in June. Interviewees included Richard Hoagland, who attempted to link the skulls and the Maya to life on Mars, and David Hatcher Childress, proponent of lost Atlantean civilizations and anti-gravity claims.>>

The universe always surprises to me, but years ago when I first saw a photo of this nebula, I was droolling, as it was possible formation of that nature?
Now, I know the data of 10 light-years diameter, I am surprised all over again.

I know everything is in the eye of the beholder, but it looks more like a 'balloon' nebula to me. The string of stars appearing to come from the beneath makes it look like a balloon floating through space. Either way, it is beautiful!

There's a little space girl??

Congrats to Dave Jurasevich for his image's selection as an APOD!

What an interesting view! It does look like a giant soap bubble. Maybe the little space girl got married? :mrgreen: 10 light years across; that's a pretty good stellar wind from the O type star. 8-)

Image The Bubble Nebula

Explanation: Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Above and right of the Bubble's center is a hot, O-type star, several hundred thousand times more luminous and approximately 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. A false-color Hubble palette was used to create this sharp image and shows emission from sulfur, hydrogen, and oxygen atoms in red, green, and blue hues. The image data was recorded using a small telescope under clear, steady skies, from Mount Wilson Observatory.
