Observatory domes for astronomers are the equipments which have become popular round the globe. In olden days, it was the equipment which was mainly used in museums and laboratories, but now you can find these devices even in residential areas. Most of the amateur astronomers install it in their gardens or backyards for different purposes.
Mainly astronomers use it for viewing the star movement, for observing the things happening in the entire universe. Mostly people who are fond of staring at the sky and stars use this equipment for making researches. Well if you are among one of them, then you have stepped up to the right place. Today skimming through this article would enable you to get to know about domes and their different features.
There are some features of the observatories which you must look up while buying one such device: these are as follows: the first thing is the maintenance cost, you must select the dome which cost you minimum in maintenance. There are some devices which requires maintenance only once in a year. Secondly, you must look up for the weather-proof equipment.
There are some of the observatories which are water-resistant, which can withstand cold, and heat. Moreover you should find water proof equipment; it should withstand rain and snow. It needs to be leak proof so that you can use it in worse climatic conditions too.
There are many uses of this device like it is also used for protecting the house from harmful and negative rays. It also acts as a shield against bad climatic conditions. You can install it in the garden or in the backyard of the house. It is used in commercial buildings like in laboratories, schools, colleges, science labs, computer labs, museums, companies, organizations and agencies.
The dome can be made comfortable in usage, if you construct a mount for it. It is found in many different sizes like in small, medium and large size. If you have bought a small-sized observatory, you can construct a mount with bricks and timber for it and can make it comfortable for usage.
There are some manufacturers who provide you the option to buy the dome of your favorite color, now it is found in many different colors and you have the option to buy the device of any color. Mostly people like to buy white observatories. In residential areas there are certain rules and regulations which you must follow for installing the dome. You need to select the color which is most suited as per your needs and usage.
Now you must be thinking of that from where to buy this device? Well if you are an individual who have heard about it for the first time, then it would require you to conduct thorough research about it and then plan to buy it. Initially you need to go through the online websites which contains information on observatories. You must read the reviews and testimonials which can help you understand it more closely.
You would be able to get to know about the price range of the domes and then you can plan out your budget. According to the budget you can start the search for buying the dome. You can buy the device as per your needs like for what purpose mainly you want to buy it, whether it is only your hobby or you want to take it professionally. The next step towards making purchases of these devices is to visit the market for viewing it closely. You can buy it through online stores, but it would be more convenient for you if you shop around in the market.
Our Sun happens to be a celestial subject that when looked at more closely, has the potential to transform the way it is commonly viewed. Instead of it just being that blinding spot above our heads that is much too intense to be looked at, it becomes an awe-inspiring burning sphere that is constantly warming up and brightening our home, and its true power and closeness can be appreciated.
In spite of this, many of us fail to think about the Sun when we bring to mind observable sights in the sky, despite it actually being the absolute brightest body around in our skies, simply because of the fact it’s only around in the day instead of the nighttime.
The Sun is really a fantastic source of enjoyment for observers when the proper safety measures are taken to be sure that zero injury to the stargazer’s eye sight happens. Simply looking at the Sun using the naked eye may cause lasting eyesight damage, and trying to observe it by means of binoculars or a telescope, in traditional fashion, is not safe because this will certainly cause the loss of one’s sight very rapidly. Fortunately there are numerous safe methods of look at the Sun and enable one to observe the Sun’s remarkably lively surface.
While viewing the Sun you may take note of one of its more interesting phenomena, the sun spots upon its exterior. These darkish patches are actually parts which are cooler than the majority of the Sun’s outer surface. They’re caused by magnetic activity found at these locations blocking heat transfer through convection.
Sunspots undoubtedly are an active phenomena, always forming and diminishing. They can remain present for several hours to many months at a stretch. The greatest ones are known to be 50,000km and can be successfully observed by way of a telescope with a appropriate solar filter.
Looking straight at the Sun just isn’t safe, fortunately there exist three basic means to view the Sun besides the expensive equipment which are only found in observatories or astronomical satellites. The first one is pinhole projection. This can be done by making a tiny opening into a piece of paper or a card and then holding it right between the Sun and another white sheet. The sunlight coming from the Sun will now project through the tiny hole and make a picture on the white surface that is perfectly safe to view.
The next technique is to project an image using an optical device. Using this method is comparable to the last, with the exception of, opposed to using a card that has a tiny opening, a pair of binoculars or a telescope is pointed at the sun so the picture is focused using the eye piece right onto empty page instead.
Make certain not to look through the telescope or the binoculars when pointed it in the direction of the Sun since it will destroy your eyesight. The third technique is to buy a solar filter, which are offered for your telescope, or to start using a solar telescope which happen to be specifically designed for viewing the Sun risk-free.
The Arecibo Observatory was built in Puerto Rico because of its proximity to the Equator and its limestone sinkholes in the Karst region which could easily accommodate the 305 meter reflector needed to enhance the power of the radio or radar telescope. The Observatory is part of the US National Astronomy and Ionosphere Center and is now operated by Cornell University.
History of the Arecibo Observatory
The Arecibo Observatory was the vision of Professor William E. Gordon, who worked in the field of ionosphere studies at Cornell in the 1950s. Construction of the Observatory was begun in 1960 and it was officially opened in 1963, when it was under the control of the US Department of Defense. In 1969 the Department relinquished control which was then given to the National Science Foundation.
It expanded its research and is now an international centre for scientists who wish to study not only the ionosphere, but planets, outer galaxies, pulsars, quasars and dark matter.
Some Scientific Achievements Made at the Observatory
As early as 1965, scientist working at the Observatory established that the planet Mercury rotates in 59 days, not in the 88 that had been previously estimated.
In 1974 Russel Hulse and Joseph Taylor found the first pulsar in a binary system and it was this discovery which proved the veracity of Einstein’s general theory of relativity, and it was for this work that they received the Nobel. Prize in physics.
Scientists working at the Observatory have assisted NASA in the preparations for some of its missions, including that of Titan. It also found a satellite of the European Space Agency with which communication had been lost in 1998. This meant that it could resume its mission and data was received from this up to 2003.
The Arecibo Message
Although the Observatory is not concerned with finding extra-terrestrial life forms as SETI is, it has beamed a message into space.
In 1974 the Observatory celebrated the update to its equipment by transmitting a message to a star cluster known as M13, 25,000 light years away from Earth. This was a message in a binary string put together by the scientists Frank Drake and Carl Sagan (the latter successfully popularized science through his television series).
If the message is eventually received and deciphered, an alien civilization would have an image of a human being, one of the actual telescope which beamed the message to it, the DNA of humans and an image of the solar system.
The Angel Ramos Visitor Center
Visitors to the center are given talks on the basics of astronomy and atmospheric science, and will gain an understanding of how the telescope works and of the work that is carried out at the Observatory. There is a platform from which they can see the reflector and when they leave they will have an understanding of how the telescope works.
There are interactive exhibits which are ideal for children, as they can have hands on experience and learn more about their universe, and what is out in space that we cannot see without sophisticated tools. They will be excited when they see images of pulsars, quasars and dark matter, which is the stuff of science fiction fantasies.
If you visit Puerto Rico, there are many tours to this Observatory on offer, and some also offer tours to other parts of this Caribbean island. You can also organize you own appointments for visits, and the Visitors Center is open from 9amto 4 pm every day except for public holidays. If you are interested in the world around you and the way it works this should certainly be on your itinerary.
