Jupiter and the Leaves Before the Storm by Radical Retinoscopy, on Flickr

111 thirty second exposures were combined using StarStaX to make this 55 minute star trail exposure. This photo was taken in Lancaster, Pennsylvania as the centered tree was illuminated by a waxing moon. Supplementary lighting was done by light painting with a LED flashlight. The camera was a Canon t2i with a Sigma 10-20 mm lens at f/4.5 at ISO 400. I was fortunate the weather and conditions were favorable this evening to take this photograph. A few days after this photo was taken, wind and rain from hurricane sandy stripped the beautiful leaves from this tree.

The view looking up at Cygnus and the Milky Way from the antenna farm next to the Mt. Wilson Observatory is a reminder that our broadcasts are also being sent to the stars. The bubble of our radio transmissions is currently around 100 light-years in radius, plus or minus a few years, depending if you measure from our first dots and dashes or voice transmissions.

The antenna array is the main point for commercial broadcasts covering the Los Angeles Basin. From 1928-1980, Mt. Wilson Observatory was operated in a partnership between the Carnegie Institution and Caltech, but is now operated by the independent Mt. Wilson Institute. Illumination is from the rising nearly full moon as well as the lights of Los Angeles.

The Tarantula Nebula and Super Star Cluster R136
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Link to large image (2MB)

The Tarantula Nebula, named for its appearance that somewhat resembles a giant spider in the sky, is the largest known emission nebula in the Local Group of galaxies. It is about 1000 light years wide and would appear incredibly bright if it were located in the place of the Orion Nebula. It is however located 160,000 light years away in the Large Magellanic Cloud, the largest of the dwarf galaxies that accompany our Milky Way.
In the very centre of the nebula lies R136, a super star cluster which is a very large region of star formation thought to be the precursor of a globular cluster. It is a very young cluster at only 1-2 million years and consists of giant and supergiant stars of which the majority are spectral type O3. The cluster also contains several Wolf-Rayet stars.
Speculation long sorrounded the nature of the central component of the cluster, named separately as R136a, and it was once thought to be a single hypergiant star of an incredible 1500 solar masses. R136a's true nature was recently resolved by holographic speckle interferometry and found to be a dense star cluster containing very massive and luminous stars. Three extremely luminous stars (R136a1, R136a2 and R136a3) dominate this cluster and are separated by only 0.10 and 0.48 arc seconds. R136a1 is the most massive star found to date with 265 solar masses, as well as being the most luminous at 10 million times the brightness of the Sun.
The entire R136 super cluster produces most of the energy that makes the Tarantula Nebula visible. The estimated mass of the cluster is 450,000 solar masses, suggesting it will probably become a globular cluster in the future.
A super star cluster, named Westerlund 1, also exists in the Milky Way but is heavily obscured by galactic dust.

NGC 6357 Pismis 24 The Lobster / Crab / War and Peace Nebula
http://www.pbase.com/boren
Copyright: Harel Boren Mid Res 1600x1303 pixels - click: http://www.pbase.com/boren/image/146391038/original
Hi Res 2736x2228 pixels - click: http://www.pbase.com/boren/image/146385803

Massive stars lie within NGC 6357, the central part of which is shown in the very middle of this image. That central region spans about 10 light years and the whole expansive complex lies about 8,000 light years away in the tail of the constellation Scorpius.

In fact, positioned just below center in this view of NGC 6357, star cluster Pismis 24 includes some of the most massive stars known in the galaxy, stars with over 100 times the mass of the Sun. The nebula's bright central region also contains dusty pillars of molecular gas, likely hiding massive protostars from the prying eyes of optical instruments. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. The overall glow of the nebula results from the emission of light from ionized hydrogen gas (ref. http://apod.nasa.gov/apod/ap081009.html; http://apod.nasa.gov/apod/ap101121.html).

The unusual name of “War and Peace” was given to this nebula not because of the famous novel by Tolstoy, but was given to this object by scientists working on the Midcourse Space Experiment (see: http://en.wikipedia.org/wiki/Midcourse_Space_Experiment). They noted that the bright, western part of the nebula resembled a dove, while the eastern part looked like a skull in their infrared images. Unfortunately this effect cannot be seen in the visible-light image presented here. The object is also occasionally nicknamed the Lobster Nebula (ref. http://asterisk.apod.com/viewtopic.php?f=29&t=28928).

NGC 6357 was first recorded visually by John Herschel from South Africa in 1837. He only recorded the brightest central parts and the full scale of this huge nebula was only seen in photographs much later.
