APOD: N11: Star Clouds of the LMC (2013 Feb 11)

Post by APOD Robot » Mon Feb 11, 2013 5:06 am

Image N11: Star Clouds of the LMC

Explanation: Massive stars, abrasive winds, mountains of dust, and energetic light sculpt one of the largest and most picturesque regions of star formation in the Local Group of Galaxies. Known as N11, the region is visible on the upper right of many images of its home galaxy, the Milky Way neighbor known as the Large Magellanic Clouds (LMC). The above image was taken for scientific purposes by the Hubble Space Telescope and reprocessed for artistry by an amateur to win the Hubble's Hidden Treasures competition. Although the section imaged above is known as NGC 1763, the entire N11 emission nebula is second in LMC size only to 30 Doradus. Studying the stars in N11 has shown that it actually houses three successive generations of star formation. Compact globules of dark dust housing emerging young stars are also visible around the image.

Kind of a Horned Dolphin Nebula, thingy...or Weird Alien Kanguru, perhaps? Wow.

Neat video, on N11 Link.

Periorbital dark circles

<<Periorbital dark circles (also known as dark circles) are dark blemishes around the eyes. There are many causes of this symptom, including heredity and bruising. In most cases, the dark circles under the eyes are blood vessels that can be seen through the skin. The skin around the eyelids (periorbital skin) is the thinnest skin in the body. Like varicose veins, dark circles under the eyes are usually an inherited trait. When blood passes through the large veins close to the surface of the skin, it can produce a bluish tint. The more transparent the skin—also an inherited trait—the darker the circles appear. In people with a deep-set bone structure, shadowing can also contribute to the dark color under the eyes.>>

What does the LHA 120 stand for?

Post by MargaritaMc » Mon Feb 11, 2013 5:40 pm

Oh! :roll: :bang:

I get so STUMPED by initials!

I am making up a reference list to help me, and up to now have found them via Google. But the only initials for LHA even slightly astronomically related is Local Hour Angle. Which doesn't seen likely.

Can anyone help clarify this for me?

PS. The video is superb, by the way. Thank you for posting it, Neufer :clap:

I have a hard time imagining how big this is. If the earth was in the picture, would I be able to see it?

The entire N11 emission nebula is second in LMC size only to 30 Doradus
Apod quote
30 Doradus ... 1000 light-years in diameter

A light-year, also light year or lightyear (symbol: ly), is a unit of length equal to just under 10 trillion kilometres (or about 6 trillion miles).

Mmmm. Like Neufer said - the short answer is "No"! :wink:

There could be any number of earths around any of those stars and we'd never know from simply looking at a single snapshot. So many planets, so hard to see...
Just call me "geck" because "zilla" is like a last name.
