Simulated fly by


The Bubble Nebula is seven light-years across—about one-and-a-half times the distance from our sun to its nearest stellar neighbor, Alpha Centauri, and resides 7,100 light-years from Earth in the constellation Cassiopeia.

The seething star forming this nebula is 45 times more massive than our sun. Gas on the star gets so hot that it escapes away into space as a “stellar wind” moving at over four million miles per hour. This outflow sweeps up the cold, interstellar gas in front of it, forming the outer edge of the bubble much like a snowplow piles up snow in front of it as it moves forward.

As the surface of the bubble's shell expands outward, it slams into dense regions of cold gas on one side of the bubble. This asymmetry makes the star appear dramatically off-center from the bubble, with its location in the 10 o’clock position in the Hubble view.

Dense pillars of cool hydrogen gas laced with dust appear at the upper left of the picture, and more “fingers” can be seen nearly face-on, behind the translucent bubble.

The gases heated to varying temperatures emit different colors: oxygen is hot enough to emit blue light in the bubble near the star, while the cooler pillars are yellow from the combined light of hydrogen and nitrogen. The pillars are similar to the iconic columns in the “Pillars of Creation” Eagle Nebula. As seen with the structures in the Eagle Nebula, the Bubble Nebula pillars are being illuminated by the strong ultraviolet radiation from the brilliant star inside the bubble.

The Bubble Nebula was discovered in 1787 by William Herschel, a prominent British astronomer. It is being formed by an O star, BD +60º2522, an extremely bright, massive, and short-lived star that has lost most of its outer hydrogen and is now fusing helium into heavier elements. The star is about four million years old, and in 10 million to 20 million years, it will likely detonate as a supernova.

This. It's one of the few things that was actually worth what they paid for it.

ETA: I'm referring to Hubble.

There's that much oxygen out there?

I wonder what it looks like in natural colour.

I believe that the bubble nebula was featured in yesterday's Arfcom approved astronomy thread of the day.

Space is awesome

7,100 light years away.



And there are things behind it.




Amazing.

Me too. I didn't find out till a few years ago that they add color to the pictures we see of space.

It's crazy to think that it was first discovered 229years ago.

Yup.



And that's not all.

Hubble took a deep space shot that used a week of precious time as I recall. it was a region of space that black to all other observatories on Earth and after a week of light gathering,  to everyone's astonishment, the region was full of galaxies.  the cosmos is  beyond human intuition and capability to comprehend the distances and forces in play. distance is measured in time. the time it takes light to travel, which is 300,000 km per second, or 186,000 miles per second. the galaxies in the deep field shot are thought to be 8-10 BILLION light years away.  think about the distance.

That's a cool photo. I think I may have found a new wallpaper to replace my current wallpaper, The Pillars of Creation.

I wonder what that would look like without the background ?



Is there a way - or do we know what is in the bubble, and what is in front, and behind it?



Neat stuff - space is kinda mind boggling tho. I cannot think that big, or that far.

I'm going to take a stab at answering because I thought the same thing at first.  For me I realized that it looks a lot like what sci fi artists have been drawing or painting for hundreds of years.  The fact that in real life it looks so similar to their work gives it, at least for me, the feeling of unreality, like the cover of a sci fi book or the opening of a sci fi movie.




That makes it doubly awesome for me, because not only is it real, but so many sci fi authors and artists have gotten so close.

I may be wrong but the coloration is added based on best guesses of what things are composed of. The actual photos are B&W, they are touched up and colorized in a process similar to what is applied to old movies.

What I find most incredible is Hubble is 26 years old.

Jesus, where does the time go?

That is a very interesting observation that I hadn't thought of but once you said it made perfect sense.
