STYLE and ...............some of these
The ellipsis is one of the favorite constructions of internet chat rooms, and has evolved over the past ten years into a staple of text-messaging. Though an ellipsis is technically complete with three periods (...), its rise in popularity as a "trailing-off" or "silence" indicator, particularly in mid-20th century comic strip and comic book prose writing, has led to expanded uses online. It has been used in new ways online, sometimes at the end of a message "to signal that the rest of the message is forthcoming." [5]
Today, extended ellipsis of two, seven, ten, or even dozens of periods have become common constructions in internet chat rooms and text messages.[6]
"Elliptical commas", or, commas used in plurality for the effect of ellipsis or multiple ellipsis, have also grown in popularity online—though no style journal or manual has yet embraced them.[6]

Wikipedia information on The Sombrero Galaxy
Distance
At least two methods have been used to measure the distance to the Sombrero Galaxy.
The first method relies on comparing the measured fluxes from planetary nebulae in the Sombrero Galaxy to the known luminosities of planetary nebulae in the Milky Way. This method gave the distance to the Sombrero Galaxy as 29.0 ± 2.0 Mly (8.9 ± 0.6 Mpc).[1]
The other method used is the surface brightness fluctuations method. This method uses the grainy appearance of the galaxy's bulge to estimate the distance to it. Nearby galaxy bulges will appear very grainy, while more distant bulges will appear smooth. Early measurements using this technique gave distances of 30.6 ± 1.3 Mly (9.4 ± 0.4 Mpc).[25] Later, after some refinement of the technique, a distance of 32 ± 3Mly (9.8 ± 0.8 Mpc) was measured.[26] This was even further refined in 2003 to be 29.6 ± 2.5 Mly (9.1 ± 0.8 Mpc).[2]
The average distance measured through these two techniques is 29.3 Mly (9.0 Mpc) with an uncertainty of 1.6 Mly (0.5 Mpc).[a]
IT'S SO INTERESTING TO NOTE THAT ACTUAL DISTANCE ISN'T STATED BUT TRUST ME WHEN I SAY THAT IT IS REALLY REALLY FAR AWAY

Nucleus
The nucleus of the Sombrero galaxy is classified as a low ionization nuclear emission region (LINER).[12] These are nuclear regions where ionized gas is present, but the ions are only weakly ionized (i.e. the atoms are missing relatively few electrons). The source of energy for ionizing the gas in LINERs has been debated extensively. Some LINER nuclei may be powered by hot, young stars found in star formation regions, whereas other LINER nuclei may be powered by active galactic nuclei (highly energetic regions that contain supermassive black holes). Infrared spectroscopyobservations have demonstrated that the nucleus of the Sombrero Galaxy is probably devoid of any significant star formation activity. However, a supermassive black hole has been identified in the nucleus (as discussed in the subsection below), so thisactive galactic nucleus is probably the energy source that weakly ionizes the gas in the Sombrero Galaxy.[8]
[edit]Central supermassive black hole
In the 1990s, a research group led by John Kormendy demonstrated that asupermassive black hole is present within the Sombrero Galaxy.[13] Usingspectroscopy data from both the CFHT and the Hubble Space Telescope, the group showed that the speed of rotation of the stars within the center of the galaxy could not be maintained unless a mass 1 billion times the mass of the Sun, or 109M☉, is present in the center.[13] This is among the most massive black holes measured in any nearby galaxies.
THE MOST MASSIVE BLACK HOLE MEASURED IN ANY NEARBY GALAXY. SO FUNNY HOW THEY USE THE TERM NEARBY.
Discovery
The Sombrero Galaxy was discovered in March of 1767 by Pierre Méchain, who described the object in a May 1767 letter to J. Bernoulli that was later published in theBerliner Astronomisches Jahrbuch.[5][6] Charles Messier made a hand-written note about this and five other objects (now collectively recognized as M104 - M109) to his personal list of objects now known as the Messier Catalogue, but it was not "officially" included until 1921.[6] William Herschel independently discovered the object in 1784 and additionally noted the presence of a "dark stratum" in the galaxy's disc, what is now called a dust lane.[5][6] Later astronomers were able to connect Méchain's and Herschel's observations.[6]
HOW WERE THESE GUYS DISCOVERING ANYTHING? HOW BIG WERE THEIR TELESCOPES COMPARED TO PRESENT EQUIPMENT?
SO MANY QUESTIONS
SO MUCH SPACE TO OBSERVE
And in Copenhagen nobody can agree on how to solve our own personal problems regarding the environment.
That's why looking into Space is so cool.......
Discovery after discovery!
It's nice to know that someone like James Cameron,who is a fellow human being, can create his own world and somehow bring that vision to the screen.
AVATAR is a spectacular visual experience
Something akin to the Sombrero Galaxy and a lot closer to home......like just down the street and around the corner.

Technological applications
Rare earth elements are incorporated into many modern technological devices, including superconductors, samarium-cobalt and neodymium-iron-boron high-flux rare-earth magnets, electronic polishers, refining catalysts and hybrid car components (primarily batteries and magnets).[5] Rare earth ions are used as the active ions in luminescent materials used in optoelectronics applications, most notably the Nd:YAG laser. Erbium-doped fiber amplifiers are significant devices in optical-fiber communication systems. Phosphorswith rare earth dopants are also widely used in cathode ray tube technology such as television sets. The earliest color television CRTs had a poor-quality red; europium as a phosphor dopant made good red phosphors possible. Yttrium iron garnet (YIG) spheres have been useful as tunable microwave resonators. Rare earth oxides are mixed with tungsten to improve its high temperature properties for welding, replacing thorium, which was mildly hazardous to work with.
[edit]Global rare earth production
Until 1948, most of the world's rare earths were sourced from placersand deposits in India and Brazil.[6] Through the 1950s, South Africa took the status as the world's rare earth source, after large rare earth bearing veins were discovered in Monazite.[6] Today, those Indian and South African deposits still produce some rare earth concentrates, but they are dwarfed by the scale of Chinese production. China now produces over 95% of the world's rare earth supply.[5]
The use of rare earth elements in modern technology has increased dramatically over the past years. For example, dysprosium has gained significant importance for its use in the construction of hybrid carmotors.[7] Unfortunately, this new demand has strained supply, and there is growing concern that the world may soon face a shortage of the materials.[8] In several years, worldwide demand for rare earth elements is expected to exceed supply by 40,000 tonnes annually unless major new sources are developed.[9] All of the world's heavy rare earths (such as dysprosium) are sourced from Chinese rare earth sources such as the polymetallic Bayan Obo deposit.[10] Illegal rare earth mines are common in rural China and are often known to release toxic wastes into the general water supply.[11] A rare earth element mine in California is set to reopen by 2012. A site at Thor Lake in the Northwest Territories is also under development. Locations in Vietnam have also been considered.[9]
Chinese export quotas have also resulted in a dramatic shift in the world's rare earth knowledge base. For example, the division of General Motors which deals with miniaturized magnet research shut down its US office and moved all of its staff to China in 2006.[12]
On Sept. 1, 2009, China announced plans to reduce its quota to 35,000 tons per year in 2010-2015, supposedly to conserve scarce resources and protect the environment.[13] Other sources of rare earth has been searched to avoid shortages and China's monopoly, mainly in South Africa, Brazil and the United States.[14]
