Astronomy is exploration of space through instruments based on Earth. Space Exploration through space travel is exploration of space by travel through it, either in person or by drone. Closely associated with Space travel is Space Station, either manned or unmanned. All man-made satellites are a form of unmanned or manned space stations.

Unmanned Space travel includes the sciences of Spacecraft Propulsion, Rocket launch technology, Rocket, Astrodynamics, Unmanned space missions, and others.

Manned Space travel further includes the sciences of Microgravity environment, Space transport, Manned space missions, Interplanetary travel, Interstellar travel and Generation ship.

Unmanned space station

There are Astronomical satellites, Biosatellites, Communications satellites, Miniaturized satellites, Navigation satellites, Reconnaissance satellites, Earth observation satellites, Earth observation satellites and others. There are many different kinds of orbits possible for these devices.

Manned Space Station includes the sciences of Space Station and Floating cities.

Space colonization

Space colonization is a colossal science that includes all of the scientific disciplines needed to be able to build colonies on non-Earth planets and planetoids.

Space Colonization Justification includes the sciences of Space and survival.

Space Colony Research And Development Man can practice living on other worlds by building permanently inhabitable cities in extremely hostile environments of the Earth: The poles and the deserts. This is discussed in the articles Biosphere 2 and BIOS-3. Currently manned Earth hostile-environment stations include Amundsen-Scott South Pole Station, Devon Island, Mars Arctic Research Station, Mars Desert Research Station, climate, underwater structures for planets with oceans or very heavy atmospheres and others.

Space Colony Location is the science of figuring out the best planets and the best locations on those planets for colonization. Because water is such a necessity for human survival most searches are for locations close to some kind of water. These issues and other related issues are discussed in the articles Colonization of Mars, Mars Society, Colonization of Mercury, Colonization of Venus, Venusian terraforming, Colonization of the Moon, Artemis Project, Europa, Phobos, Colonization of the asteroids and others.

The European Radio Astronomy club (ERAC) is Europe’s only group coordinating the work of radio astronomers to jointly use radio waves to study the universe at radio wavelengths. It was founded in 1995 by Peter Wright and his wife, Angelika, who had the idea of writing a small newsletter to the then only 15-strong radio astronomy community in Europe, which were up to this date linked only by letters. Today E.R.A.C. has over 350 members in 19 different countries with a proportional membership of professionals and amateurs.

The European Radio Astronomy Club has its headquarters in Mannheim, Germany. The aim of the club to unite Europeans with a common interest in Radio Science. The main tool to do this is still a printed newsletter which goes out to all members. E.R.A.C. regularly holds an International Congress for Radio Astronomy which is attended by scientists from all over the world. Meeting in 1997, 2000, and 2003 were held at the Starkenburg Observatory in Heppenheim, before moving to the SRH University of Applied Science in Heidelberg in 2006.

In 1997, the director of the British Jodrell Bank Observatory met for the first time, the executive director of the SETI League . The result of this meeting was that SETI research was done for the very first time at Jodrell bank.

Institutes in Europe are thought to frown on amateurs with their backyard telescopes. This is in contrast with the situation in the United States; there, where amateurs had played such an important role in the birth of this new science, amateurs were tightly interwoven in all US radio astronomy work.

Narrowing the task

When looking for life on other planets, some simplifying assumptions are useful to reduce the size of the task of the astrobiologist. One is to assume that the vast majority of life forms in our galaxy are based on carbon chemistries, as are all life forms on Earth. While it is possible that non-carbon-based life exists, carbon is well known for the unusually wide variety of molecules that can be formed around it.

The presence of liquid water is a useful assumption, as it is a common molecule and provides an excellent environment for the formation of complicated carbon-based molecules that could eventually lead to the emergence of life. Some researchers posit environments of ammonia, or more likely water-ammonia mixtures. These environments are considered suitable for carbon or noncarbon-based life, while opening more temperature ranges (and thus worlds) for life.

A third assumption is to focus on sun-like stars. This comes from the idea of planetary habitability. Very big stars have relatively short lifetimes, meaning that life would not likely have time to evolve on planets orbiting them. Very small stars provide so little heat and warmth that only planets in very close orbits around them would not be frozen solid, and in such close orbits these planets would be tidally “locked” to the star. Without a thick atmosphere, one side of the planet would be perpetually baked and the other perpetually frozen. In 2005, the question was brought back to the attention of the scientific community, as the long lifetimes of red dwarfs could allow some biology on planets with thick atmospheres. This is significant, as red dwarfs are extremely common. (See Habitability of red dwarf systems).

It is estimated that 10% of the stars in our galaxy are sun-like; There are about a thousand such stars within 100 light-years of our Sun. These stars would be useful primary targets for interstellar listening. Since Earth is the only planet known to harbor life, there is no evident way to know if any of the simplifying assumptions are correct.

Drake, who turned 80 in May, is still at it, directing the Carl Sagan Center for the Study of Life in the Universe at the nonprofit SETI Institute in Mountain View, Calif. Instead of just borrowing time from other astronomical instruments, those in the field now have purpose-built tools at their disposal, such as the fledgling Allen Telescope Array (ATA) in Hat Creek, Calif. But funding is scarce–the ATA growth stalled at 42 dishes of a planned 350–and astronomers have not yet gathered enough data to make firm pronouncements about intelligent life in the universe.

“Although we have ‘been doing it’ for 50 years, we have not been on a telescope very much of that time,” says Jill Tarter, director of the Center for SETI Research at the SETI Institute. “What we can say is that every star system in the galaxy isn’t populated by a technology that’s broadcasting radio signals at this time.”

Theoretical astrophysicist Alan P. Boss of the Carnegie Institution for Science agrees. “The lack of a SETI signal to date simply means that civilizations that feel like broadcasting to us are not so common that the limited SETI searches would have found one,” Boss says. “There is still a lot of the galaxy that has not yet been searched.” One of the most extensive campaigns to date, Project Phoenix, surveyed nearby stars across a wide range of frequencies using some of the world’s largest radio telescopes. In nine years Phoenix sampled roughly 800 stars, less than one millionth of 1

Even for stars that have been scanned, the parameters for a possible signal are frustratingly numerous. Like those for terrestrial radio, they include frequency (what station does it broadcast on?), time (24/7 or midnight sign-off?), type of modulation (AM or FM?), and so on. “At the very least this search is nine-dimensional,” Tarter says, “and we could guess right about what to look for and build the right instrument for eight of those dimensions, but we could still miss it because we got one wrong.”

Arguments for SETI and for widespread life in general have been bolstered by the confirmation that planetary systems are common around other stars. Most of the 400-plus exoplanets are scalding giants inhospitable to life as we know it. But in the next few years NASA’s Kepler space telescope, now surveying more than 100,000 stars for planets, should settle the question of how common Earth-like planets are.

Even on Earth-like worlds, however, technological, radio-broadcasting life may not be common. Many researchers hold out more hope for finding simpler life-forms, such as microbes or slime molds. Boss says that life of this kind should be widespread, but we will not have the technology to detect it for two decades at best.

But what if someone does pick up a signal from an intelligent civilization? The SETI community has protocols in place, such as alerting observatories around the world for verification, but the same cannot be said of the world’s governments. A United Nations-level framework does not yet exist to guide the contentious next steps– if we hear a shout from a potentially hostile neighbor, do we dare shout back?

It would not be an entirely new experience for Drake, who as a graduate student thought he had made a detection. “You feel a very special emotion if you think that has happened, because you realize everything is going to change,” he says, noting that we would soon be enriched with new knowledge of other worlds, species and cultures. “It’s an emotion you have to feel to understand, and I felt it.”

King Ramses II , who reigned for 67 years during the nineteenth dynasty of the 12th century BC, was notable as “Ramses the Great”. He is known as one of Egypt’s quality warriors, but too as a peace-maker and for the memorials he left behind all over Egypt. He was the first king in history to signal a peace pact with his oppositions, the Hittites, finish long years of warfares and aggression.King Ramses dominated for 67 years (1292–1225 B.C.). Under him Egypt acquired unprecedented grandness. His empire huge from Syria to near the Fourth Cataract of the Nile.

King Ramses given repositories throughout Egypt. The essential ones are probably the temple at Karnak, which he completed; the Rameseum, his mortuary temple, at Thebes; the temple at Luxor; and the special rock temple at Abu Simbel with four seated forms of the king on the facade. The menstruation of his rule was characterise by great luxury, accumulated slavery, and the growth of a mundane army, all of which directed to the final decline of Egypt.

King Ramses II was born to Queen Tuy , his father king Seti I. He was passed the throne at the age of around 20 and ruled for 67 years. This allowed him to be the second longest ruling king. Successor to Harmhab and rule of ancient Egypt during the 19th and 20th dynasties King Ramses I was grandfather of Ramses 2. This boy of Seti, who was non heir to the throne but alternatively upsurped it, bestowed Egypt to unexampled brilliance during his long reign from 1292 B.C to 1225 B.C. Born about 1303 B. C. in the eastern River Nile Delta,

Ramses given a great number of edifices alike the new capital in the River Nile delta. He ended the pillared great hall in the temple of Amon-re at Karnak. At Abu Simbel Ramses established the rock temple and taken reference for many of his ancestor’s constructions. His honey of architecture and force left him to hard more memorials and temples than any other Egyptian Pharaoh.  Temple of Abu Simbel, credibly Ramses II’s most amazing structure was etched from a sandstone cliff that looked to the eastside. This was settled in ancient Nubia.  Although Abu Simbel remains his nearly identified construction, he had many another more architectural proposes. Among them, is taken the expanding upon of Luxor and Karnak.  There he finished earlier projects set forth by his father and erected many another more monuments.  It was noted Ramses II wanted to leave a set as a reminder of his great strength and wealth.

Nowadays, it cannot be stressed enough how having an outdoor swing setis important in keeping your children in good health. Because of technology, urban development and the constant demand for children to excel at an early age these days, most children do not get to play outside anymore. Instead, they get to sit in front of the television set, the computer or the latest gaming console.

And yet, staying indoors and sitting stagnantly for long periods of time are not good for children. They should be encouraged to play indoors every once in a while so that they can stay healthy and promote their physical development. A good outdoor swing setis the perfect toy that will push them to go out and play.

But how exactly can an outdoor swing setpromote better physical health for children? Here are four reasons why an outdoor swing setis good for keeping children healthy.

1. It gets them to exercise. An outdoor swing setwill force your children to move. Children these days are resistant to any physical activity that they see labeled as “exercise” and would rather play computer games or watch television. But when they see the exercise as “play,” they are more likely to get into it wholeheartedly. With an outdoor play set, they get to exercise as they push their playmates on the swing, climb ladders, swing on monkey bars, go down on slides and generally just run around.

2. It strengthens their bodies. Because an outdoor swing setgets the children to exercise, their bodies in turn become stronger and less resistant to ill

3. It helps develop motor skills. Since children get to move a lot with their outdoor play set, they also get to develop their motor skills. They will learn to have a better sense of balance and a keener sense of space, which will help them coordinate their movements with a lot more ease and comfort. They will also develop sharper reflexes, which can save them from getting into accidents and injuries in the future.

4. It gets them to sleep better at night. Studies have shown that children who do not get enough exercise often find it hard to sleep at night. A good night’s sleep is essential to a child’s mental and emotional development, and so a child must have around eight hours’ sleep at night. Because their bodies are tired out by playing with their outdoor play set, children would not have any trouble sleeping come bedtime.

Being able to play outdoors is a very important element to your child’s physical development. It keeps them healthy and helps them develop resilience against diseases that may affect them as adults. A good outdoor swing setwill help address this need for your children to have some exercise.

Outdoor swing set is available in several different, versatile “configurations” available at http://www.creativeplaythings.com

The temple of Karnak is a vast complex that was built over a 1,300 year period and is considered to be the largest temple ever built by man. While originally started to honor the god Amun, it was expanded over time to include many smaller temples.

There are three main temples dedicated to Mut, Montu and Amun, which are enclosed by enormous brick walls. The main complex, The Temple of Amun, is located in the center of the complex. The Temple of Monthu is to the north of the Temple of Amun, while the Temple of Mut is to the south. There are also smaller temples dedicated to Khonsu, Opet, Ptah and Osiris Hek-Djet.

Inside the Great Temple of Amun is the Hypostyle hall. The hall is considered to be one of the world’s greatest architectural masterpieces. Construction began during the reign of Ramesses I, who was the king that founded the Nineteenth Dynasty. While Ramesses I was king for only one year, the work continued under Seti I. Construction was then passed on and completed by Seti I’s son, Ramesses II.

The walls, ceilings and columns are painted with the natural earth tones. The hall ceiling was 82 feet high and was supported by 12 papyrus columns. The columns are made of sandstone and set in two rows of six. Each row is flanked on either side by 7 rows of columns that are 42 feet high. The reliefs throughout the hall contain symbols of Creation. The reliefs in the northern half are from the time period of Seti I and are obviously better done than those completed under his son Ramesses II, which are located in the southern h

The outer walls of the Hypostyle Hall are covered with scenes of battle. Over time, the scenes have lost their color and the outlines of the scenes have been blurred by the centuries of wind and sun. It is unclear whether the scenes of battle are based on historical fact or of ritual significance. It is thought that when the battle details are very precise, real events are most likely involved. Seti’s battles take place in Lebanon, southern Palestine and Syria. The southern walls of Ramesses II have hieroglyphic texts which actually record details of the Hittite king and Ramesses II signing a peace treaty in the twenty-first year of Ramesses reign. This is the first evidence found for a formal diplomatic agreement and is certainly historical.

Leaving the hypostyle hall, there is a narrow court where there once stood several obelisks. One of the obelisks was erected by Tuthmosis I, who was the father of Hatshepsut. This obelisk stands 70 feet tall and weighs about 143 tons. During the centuries between Tuthmosis I and Ramesses VI, it was common practice to dismantle older structures and reuse the pieces for new temples and buildings. Amazingly, this obelisk was never touched. The original inscription was left in place however two kings did add their inscription on either side of the original.

Beyond this obelisk is the only remaining Obelisk of Hatshepsut. It is 97 feet high and weighs approximately 320 tons. Hatshepsut was a woman who considered herself a Pharaoh, thus challenging the tradition of male kingship. After her death, her name and memory suffered systematic obliteration.

The top of Hatshepsut’s obelisk was visible for 50 miles. The pink granite for the obelisk was quarried at Aswan, which is located several hundred miles south of Karnak. The stone was moved several miles over to the river and shipped down to Thebes. The setting of the stone is shown on reliefs as the pharaoh raising it with a single rope tied to its upper extremity. This is most probably symbolic, but may have been done this way with several hundred workers pulling together.

Tuthmosis III was Hatshepsut’s successor. When he came to power, he constructed a high wall around her obelisk. This wall hid the lower two-thirds but left the upper towering above. It has been thought that this was an easier and cheaper way of destroying her memory than actually tearing it down and removing it.

For those with a love of mp3 music, beware white noise. Report any unusual signals and sounds you pick up to the authorities and switch off immediately. Do not, under any circumstances, attempt to decipher or interact with these noises.

It is feared that unintentional and un-thought out communication with extra terrestrials will herald a wave of unwanted attention from alien beings and this is totally illegal, what the unofficial embargo on unauthorised communications with other worldly beings. It is also thought that music may be the medium of choice for these communications.

NASA, for reasons strictly on a need to know basis, beamed a Beatles track towards the North Star, much to the consternation of SETI, the organisation that is searching for life on Mars, or any other planet come to that.

Fortunately, this slip up on behalf of NASA has caused no unwanted attention – so far. Advertising humanities place in the universe without organised back up could possibly be responsible for the wiping out of mankind. Any alien species capable of picking up any communication from earth, deciphering it and having the means to find us would be far more advanced than mankind and assumed unfriendly.

According to the SETI institute, if symbolic messages are sent into outer space, there needs to be worldwide consultation on what they will say, if anything is sent at all.

For those of us with mp3 music, how about we all get together and have a simultaneous session of playing The Cheeky Girls? Surely that would be enough to deter an

We could arm ourselves with mp3 music from David Bowie. He always had a fascination for beings from outer space. Bowie suggested there was a starman waiting in the sky, he’s like to come and meet us but he thinks he’d blow our minds. He also suggests we try tuning into channel two on the TV to make contact. Not quite beaming music into space but you never know.

Continuing with the Mars theme, Blondie produced Rapture. In the musical sense, not the physical, unless you were a late teen in the early eighties when she would have done it for you. However, I digress.

According to her music, out comes a man from Mars, you try to run but he’s got a gun. He shoots you dead, then eats your head, then you’re in the man from Mars and go out all night eating cars!

Aiming our mp3 music towards Mars with this kind of offering is bound to put them in a bad mood!

Sheb Wooley thinks he knows how to identify an alien. Apparently, they are purple people eaters with one long horn, one big eye, pigeon toed and undergrowed. If you get accosted by anything matching this description whilst listening to your mp3 music, be sure to hand over the goods and report this incident to your nearest mental institution for evaluation.

Of course, any fans of the Carpenters mp3 music will appreciate their more professional approach to alien interaction. They realise that ‘in your mind you have capacities….to telepath messages through the vast unknown’. They are calling occupants of interplanetary craft, acknowledging ‘you’ve been observing our earth’ and reassuring them ‘we’d like to make contact with you, we are your friends’.

And just how do they know? If SETI are right in what they are saying, and aliens may not be little green men with cute faces and three fingers, then maybe we should be more careful what we put across the airwaves.

Let us tell you a few words about what a screensaver is. A screensaver is a small program which gets started automatically when a user do not operates computer for a certain period of time. All the operating systems offer some standard screensavers which, unfortunately, make a nuisance of themselves very soon. That is why most of the advanced users start surfing the Net in order to find something new and eye-catching for their desktops. For this purpose there are lots of portals where a great variety of screensavers is given. All the possible themes and scenes are available there. Thus, users may choose and download a screensaver on their PCs in accord with their taste. On account of the great demand on screensavers among Web users, they started to be used for much more purposes then before. Let’s have a look on the main field of screensavers application.

ADVERTISMENT

A screensaver may be considered as a small media presentation with animation and musical illustration. This property of a screensaver gives an opportunity to promote almost any brand in business. When creating such a screensaver you should take into account the target audience of the brand, goods or services. After market analyses and primary audience definition such a screensaver becomes an effective tool to affect on the target audience.

CRPORATE STILE

Corporate style should be represented almost everywhere and office PC desktop is not exclusion. This method gives a good opportunity to emphasize company stile, it build positive business image in the eyes of clien

SECURITY

Most of the screensavers may be installed with a lock. You may ask us how it works. Let us describe the procedure in a few words. If you need to leave your work place with PC on, then a screensaver may start running automatically (or you may even start it by your own). Thanks to this screensaver peculiarity nobody will see your secret information on the desktop before screensaver is unlocked with your secret password.

DISTRIBUTED COMPUTING

The idea of such screensaver characteristic is rather easy. If your computer has an Internet outlet or local network, its computing power will be used by the others at the moment of the downtime. A PC accepts data block, operates it and sends the analyzed information back. An instance for it may exemplify SETI project (http://www.seti.org/) or Search for Extraterrestrial Intelligence and for such projects screensavers may be very useful.
