APOD: Close-up of the Bubble Nebula (2016 Apr 03)

Post by APOD Robot » Sun Apr 03, 2016 4:07 am

Image Close-up of the Bubble Nebula

Explanation: It's the bubble versus the cloud. NGC 7635, the Bubble Nebula, is being pushed out by the stellar wind of massive central star BD+602522. Next door, though, lives a giant molecular cloud, visible to the right. At this place in space, an irresistible force meets an immovable object in an interesting way. The cloud is able to contain the expansion of the bubble gas, but gets blasted by the hot radiation from the bubble's central star. The radiation heats up dense regions of the molecular cloud causing it to glow. The Bubble Nebula, featured here in scientifically mapped colors to bring up contrast, is about 10 light-years across and part of a much larger complex of stars and shells. The Bubble Nebula can be seen with a small telescope towards the constellation of the Queen of Aethiopia (Cassiopeia).

Has anybody noted that the molecular cloud formation in the lower left of the image [pictured today] resembles the Statue of Liberty? Or is this particular formation already named?

I kind of see your "Statue of Liberty"... but up above that, I see an Angel...wings expanded and all...

What would a Molecular Cloud be doing inside a bubble?
Molecular Clouds are dark, are they not? Like the example...

Close up ???? Interesting irony. This item is 10 light years across, if we could get close to it we would no longer be aware of it.

<<A close-up or closeup ... is a type of shot, which tightly frames a person or an object. Close-ups display the most detail, but they do not include the broader scene. Film historians disagree as to which filmmaker first used a close-up. One of the best claims is for George Albert Smith in Hove, who used medium close-ups in films as early as 1898 and by 1900 was incorporating extreme close-ups in films such as As Seen Through a Telescope and Grandma's Reading Glass. In 1901, James Williamson, also working in Hove, made perhaps the most extreme close-up of all in The Big Swallow, when his character approaches the camera and appears to swallow it.>>

Reminds me of the closing scene in 2001 - A Space Odyssey.
