Those Nebulous Days of Summer
My two daughters lounge on the grass contemplating the magic of space.
From APOD: Double, double toil and trouble; Fire burn, and cauldron bubble — maybe Macbeth should have consulted the Witch Head Nebula. This suggestively shaped reflection nebula is associated with the bright star Rigel in the constellation Orion. More formally known as IC 2118, the Witch Head Nebula glows primarily by light reflected from bright star Rigel, located just off the upper right edge of the full image. Fine dust in the nebula reflects the light. The blue color is caused not only by Rigel’s blue color but because the dust grains reflect blue light more efficiently than red. The same physical process causes Earth’s daytime sky to appear blue, although the scatterers in Earth’s atmosphere are molecules of nitrogen and oxygen. The nebula lies about 1000 light-years away

When I step out onto my balcony and look East, I always have magnificent views. I look towards the ridge opposite my house in the Dandenong Ranges. There are frequent colorful sunrises that materialise behind the dead branches of a large tree jutting through the forest canopy. You’ll find a number of photos from my balcony with the tree top as subject (just see yesterday’s post).
I took this image some time ago and was struck by the contrast between the red rising sun and the black early morning sky. I then wondered, what would this view be like if we were much closer to other star systems. What if a nebula was a nearby neighbor? Here’s my minds eye of what that would look like. I’ve combined an image of nebula NGC 1333 with my tree view.
This image of NGC 1333 was taken using the Mosaic-1 imager and the National Science Foundation’s Mayall 4-meter telescope at Kitt Peak. This star-forming region, located roughly 1,000 light-years from Earth in the direction of the constellation Perseus, harbors hundreds of newly formed stars less than one million years old. Many of these proto-stars exhibit energetic activity such as jets and strong stellar winds. NGC 1333 credit T.A. Rector/University of Alaska Anchorage, H. Schweiker/WIYN and NOAO/AURA/NSF

Here’s another Zenwalk Linux wallpaper. This one is based on my Nebula In My Backyard II image. The image featurres a photo off my balcony early one morning superimposed upon a Hubble Space Telepscope shot of the Orion Nebula. Download a hi-resolution version (1800×1200) here.

Call me an adult with an overactive imagination, a dreamer or a delusional geek but sometimes I just can’t help but wonder … What would my backyard look like if Earth was a little closer to the Orion Nebula?
Ah, now that’s worth pulling out the deck chairs and a pondering over a tequila sunrise.
Hubble’s Sharpest View of the Orion Nebula:
The Orion Nebula is a cavern of tumultuous gas and dust where thousands of stars are forming. The energy released by the young stars transforms their place of birth, whipping their surroundings into fantastic forms.
The Orion Nebula and God's Grove
This image was inspired by Dan Simmon’s book Hyperion. In it there is a planet called God’s Grove. God’s Grove is a forest planet, home of the Templars, whose worship of nature seeks to mold life to preserve and spread it throughout the galaxy. The Templars designed their star ships to look like giant trees.
High resolution images taken of Space are grand and majestic. However, few people have exposure to them. Occasionally I’ll develop a concept like this to utilize these powerful images. I do this for my own gratification but also to hopefully encourage more people to develop an appreciation and desire to learn more about objects in our heavens. The image above uses a Hubble Space Telescope shot of the Orion Nebula.
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south[b] of Orion‘s Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,270±76 light years[2] and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. Older texts frequently referred to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula. Yet older, astrological texts refer to it as Ensis (Latin for “sword”), which was also the name given to the star Eta Orionis, which can be seen close to the nebula from Earth.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
If you get a chance, read some of Simmon’s books. He does an excellent job of blending classical literature with Science Fiction and also, take the time to look upward and appreciate the majesty of space.
