What To Know About Backyard Astronomy

Getting started in backyard astronomy is actually easier than most people realize, because they’ve got all the tools they need right in their heads. This means, of course, that their eyes are the single best instruments for at least starting out in astronomy that they’ll ever use. Most experts advise that one learn what’s up in the night sky before buying a telescope, as a matter of fact.

What this means is that taking the time to gain just a little bit of knowledge about the objects existing in the nighttime or daytime skies is important to the study of astronomy. In fact, it can be far more enjoyable once one has a working understanding of celestial objects, such as galaxies, constellations, the planets and the like. Understanding these objects before starting out will increase enjoyment, for a fact.

Once this basic understanding is gained, it will then be time to start thinking about the kinds of astronomy and study of the skies that one wants to get involved in. Just go online or go to any bookstore and look in the astronomy section to get an idea of how vast the field really is. After all, with billions of galaxies, innumerable suns, moons and stars there’ll certainly be much to study, right?

Consider all of these pre-astronomy activities as being preparation for really getting into the pastime. With them, one’s better equipped to start seeking out astronomy clubs and also selecting a good quality telescope. A club can help in this regard because its members can make recommendations about telescopes and also about what forms of astronomy for the backyard may be the easiest to start out on.

As far as telescopes are concerned, for those just starting out in astronomy it’s a good idea to learn what they are and what they’re capable of. In truth, one doesn’t have to spend a lot of money to get a nice telescope that will be just fine for backyard activities. It’s important, though, to gain an understanding of telescope so that one knows exactly what it’s capable of doing, depending on the circumstance.

If one is just starting out, and needs to stay within a budget, it’s a good idea to find a telescope that strikes a good balance between price and magnification, for example. How “strong” is the telescope? “How wide is the telescope’s field of view?” is always a good question to ask before deciding to buy one. Ask, also, how portable the instrument will be and how easy will it be to move it so that objects in the sky can be tracked.

There are many resources available online for those wishing to get started in backyard astronomy, fortunately. Planetariums are also fantastic when it comes to at least getting started in the right direction, as well as local astronomy clubs (planetariums usually have lists, as do colleges and universities). A nice quality telescope used for amateur astronomy may cost less than 100 dollars, by the way, so why wait to get started?

Why Do Americans Love The Meade Telescopes?

Man had great fascination for observing celestial bodies from ancient period. Naked eye was one of the means by which the planetary positions were observed. This was a means which astronomers like Aryabhata, Bhaskara and Copernicus used before the invention of the telescope by Galileo. Pole star played an important mark by providing ancient astronomers the reference point they needed and this helped in the forecasting of eclipses keeping the relative positions of the stars in the calculations. Pole star in ancient Egypt was used in the construction of the pyramids by providing the perfect reference point in the night sky.

When telescope was invented in the 15th century it opened up a new field of view for space exploration. With the invention of telescope, the geocentric concept of the solar system was wiped away with a more rational heliocentric theory was put forth. Telescopes have undergone a great revolution with what used to be only possible to view the neighboring Venus and Mars being now stretched to the outer half of the solar system with the likes of Jupiter and Uranus being explored with ease. It is believed that with the current pace at which the technology is growing the dwarf planet Pluto can also be scaled without difficulty in the near future. Today there are alternate means which are used to observe distance stars and planets like x-rays and reflections from the stars.

With the availability of a wide range of telescopes the current scope of astronomy has widened greatly. Not long ago, people had to visit planetariums or observatories to know about the beauty of the stars and the planets. But this has changed with low cost telescopes being available that offer portability and ease of use. A large proportion of the astronomers community are amateurs who would be interested in enjoying the beauty of nature more than going in depths about scientific figures and calculations. There are telescopes like the Meade Telescopes that offer the amateur astronomers the space exploration at their homes.

Diameter of the aperture and the power of the lens go along way in determining the resolution the telescope can provide with its increased capability. Telescope makers provide manuals containing detailed instructions on how the telescopes can be assembled. Some maker’s do the assembly themselves for the customers should they require it. An amateur telescope itself can cover the Saturn’s rings on a clear night.

Telescopes can be a perfect way to enjoy and learn about astronomy. So, it would be best to choose the ones of good quality.

Why You Might Use Solar Power

If you are tired of paying for steep power bills and are looking for an alternative, then you might consider the use of solar power for your home. There are systems that go on your home and can create a source of power for the house to receive from the sun. This can reduce your bill totals and help the environment out.

When you think about all of the perks to buying some solar units, it only makes sense to do it. In fact, it is a wonder that more people do not follow this idea. Doing your part for the environment and saving money are two very good reasons to make the switch.

To find a source of solar energy makers, you will have to look them up online. When you have some manufactures info in front of you, then you might contact them to find out what their prices and packages include. They can tell you all about their products and give you an idea of how they install it and what process is involved.

The price of these panels depends on the make and the amount that you get. Some people will only get enough to heat half of the house and then rely on their bills to cover the rest. Whether the panels are for the whole home or just a part of it, they will be expensive initially to purchase. However, most claim that it is paid off in just a few years and then there are no more payments left. It is almost like your heat becomes free.

If everyone did their part and did not use so much electricity and heating for their home, then it would greatly help out the environment. However, even if just a few people are trying it for now, it is just a matter of time before it begins to catch on and others start to follow.

The use of solar energy is received from the sun and stored during the day. That helps to heat the home for a period of time, before it needs to be recharged again. Even if your area is mostly cloudy, it is common for houses to not be effected by this. The sun’s rays can break through cloud coverage and still provide a good provider of power.

The only issue that some homeowners have is that if there is snow in the area of the home, that the panels can become snow covered. That might leave the person to have to climb on the roof to clear it off. It might be tricky if you live in a cold and snowy climate, unless you are okay with roof climbing once in a while. Most panels are so slippery that snow just melts off or falls away.

The use of solar power is becoming more popular around the entire globe. As more people catch on to the great idea, it is helping the environment and putting money back into people’s pockets where it belongs.

Since 1970, the top retailer for solar power offers a wide variety of resources to aspiring scientists, kids science projects and science lab equipment. Learn about alternative energy solutions, among other scientific knowledge, with these high-quality alternative energy labs. Take advantage of the Feed in Tariff program and use alternative energy.

Do you feel nostalgic when you see small children fighting over owning a star in the sky before they go to bed? Are you one of those who as a child gazed the night sky to find the brightest star? Then, you should have one of the finest telescopes at your home to bring back those childhood memories. Telescope is a fabulous invention of mankind. You can explore the endless sky with the help of telescope without much effort.

A small reflector telescope would do, if you are buying it for home use. It is a tricky proposition to buy a telescope in any case. You should know the type of telescope that you need before going ahead with the purchase. If you do not know, ask an expert. Once you buy the telescope find a flat surface in your home from which maximum sky could be explored. If you have kids at home, they will enjoy looking through the eye pieces of the telescope. The enormous highly resolved moon is a fascinating experience for the kids.

So, I think, I have inspired you enough to go and buy a telescope right now. Before you rush to the shop for a buy, you should do some research and find the type of telescope that you want for your home. If you want to become a professional astronomer, then, you have to do a bit more research and talk to different experts in astronomy explaining them your needs and your future plans to become a professional. The experts might suggest you to buy a variety of eye pieces and filters that could provide greater magnification and protection to your eyes respectively. It is of utmost importance to take good care of your eyes along with enjoying the experience of seeing the deep sky objects much closer.

International astronomy day is celebrated on May 10th of every year and on this day you must visit one of the planetariums in your city to see what the current treads in the astronomy are and enjoy all the fabulous events on offer. If you know that there is an eclipse that is going to happen, then, you must visit a planetarium during that time to see the eclipse much closer.

Don’t wait too long to get your telescope though. You might miss some great sights!

Astronomy – Important Pre-Christian Dates

There is no uncertainty that astronomy is the oldest science and there is also no hesitation that astronomy was being studied by everyone, not only the wise men, thousands and thousands of years ago.

We do not understand exactly why they did it, but we can surmise that early man noticed a correlation between the weather and the stars, which were themselves not fully understood, of course.

Early man, almost certainly even as far back as Neanderthal man, noticed the connection between the weather and herd movements and crop growth, or at least fruit and nuts on local trees, if they did not have planted crops.

This means that people could see a connection between the stars and food availability. This relationship was probably ritualized into some sort of religion like early Wicca. Therefore, the stars became a very important part of the lives of every single person and it is likely that astrology and astronomy were widely intermixed by the average person.

However, there were also people who did not only use the stars as some enormous celestial clock and who tried to make sense of the whole shebang. I am going to narrate below, eight of the most important dates or years in the history of astronomy before Christ walked on the Earth. Never forget that they had nothing but an abacus to do there calculations and no telescopes, which came about two thousand years later.

585 BC: Thales of Miletus (c. 625- c. 547), a Greek, predicted a solar eclipse in Asia Minor purely on the basis of his observations and calculations. It was not a lucky guess!

c. 400 BC: the astronomer Oenopedes (5th. century). also a Greek, announces that the Earth is tilted on its axis with respect to the Sun.

352 BC: the Chinese report what they called a ‘guest star’, a supernova, which was the earliest reported sighting.

340 BC: The astronomer, Kidinnu (b. Babylon c. 379 BC) discovers the precession of the Equinoxes, ie the apparent change in the position of the stars caused by the Earth’s wobbling on its axis.

c. 300 BC: a ‘committee’ of Chinese astronomers compile star maps of the visible universe.

c. 240 BC: Chinese astronomers observe and make notes about Halley’s Comet. Also Eratosthenes of Cyrene (c. 276 – c.194 BC), a Greek, correctly calculate the Earth’s dimensions.

165 BC: Chinese astronomers notice sunspots for the first time.

c. 130 BC: the astronomer Hipparchus of Nicea (b. 147 BC), a Greek, correctly calculates the distance to the Earth’s Moon and also rediscovers the precession of the Equinoxes.

You will see from the dates above that clearly not everyone let nature and the stars govern their lives, as the common farmer or hunter did. Some men actually put pen to paper, but before pen and paper even existed, and tried to work out ‘why these manifestations took place?’.

These individuals must have been remarkable men to have worked these measurements out by calculation, observation by the naked eye and rationalization alone.

The Chinese Lunar Calendar

Previous to their implementation of the Western solar calendar scheme, the Chinese almost exclusively followed their own lunar calendar for determining the times of planting and harvesting and festival days. Although people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old system still serves as the basis for working out numerous recurring holidays. This coexistence of two calendar schemes has long been acknowledged by the people of China.

However, this does not only apply to China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.

A lunar month is determined by measuring the period of time needed for the moon to complete its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is corrected every 19 years by the addition of seven lunar months.

The 12 lunar months are further divided into 24 solar divisions characterized by the four seasons and times of heat and cold, all of which bear a close relationship to the annual cycle of agricultural work.

The Chinese calendar – very much like the Hebrew calendar- is a combination of the solar and lunar calendars in that it strives to have its years coincide with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.

For example, an ordinary year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When determining what a Chinese year will be like, one needs to make a number of astronomical calculations.

First of all, you have to work out the dates for the new moons. In these instances, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used by the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.

The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Julian calendar.Anyone who sought to work with them had to follow suit. This is why national policy often differs from local custom in Third World countries.

The government desires to trade on the International markets, but the normal family in the country can not. So, the government adopted the Julian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for example and no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for instance in Muslim countries.

Astronomy Telescope, Endless Possibilities For Imagination And Education

Where would mankind be today in discoveries if not for the invention of the astronomy telescope? Not as far as putting a man on the moon? Or maybe the space shuttle would still be a few years in the making? None of us would know what planets were up there and the Rover probably wouldn’t be on Mars.

Galileo is the most well known inventor of a telescope. While there were a few inventors of various kinds of changes and kinds of telescopes, Galileo is the more well known of them all. When he brought into focus the stars, he had no idea the possibilities that would later be discovered due to his invention.

If you are planning on getting your own telescope, you are going to need to know a bit about them first. There a many different kinds to choose from, so you will want to be able to get the one that is going to suit your viewing needs. A refractor telescope is the kind that uses the bending of air to enable you to look through the eyepiece and see those stars up close and personal. The light from the air bending when it hits the medium glass is what causes you to be able to see everything in the heaven’s that your telescope can bring down to you closely.

Reflecting telescopes are a little different in that they incorporate images from the reflections of a few mirrors, then that reflection goes back to the eyepiece so you can see it. This is one astronomy telescope that has undertaken many improvements since its invention and is now a great way to be able to view the night skies and see a lot of things up close.

If you are interested in learning about the stars and being able to see them clearly while doing so, then you need to go online. You can find many telescope dealers that will help you in choosing the right telescope for you. You will also need to get a few accessories such as a tripod, eyepieces, finders, specialty cleaning supplies, and a dust cover. One very important accessory is charts of what you are looking at.

You will do well to research telescopes before you make the choice of a particular one. This research will come in handy when you are talking to someone about purchasing one. Being able to tell them what you want from your telescope is going to help them in finding the right one for your star gazing.

You should let your eyes get adjusted to darkness before looking through your telescope. Stay out of bright light for a bit because going from light to dark like that will distort your vision’s ability to see well through the lens. Make sure that you cover one eye while viewing to see better. Move your telescope a little at a time for great viewing and finding things to view.

Making the choice to get an astronomy telescope will bring you hours of enjoyment and discovery. These are great to get for the kids in your family and is one awesome way to spend time with them, imagining and gazing into the heavens and seeing what is up there that we don’t know about yet.

Astronomy telescopes are sometimes confusing on which one to purchase. Go to Perception Optics/telescopes where you will find information and helpful points to help you make a decision.

Astronomy – An Introduction

Although astronomy is the oldest science, it continues to be at the forefront of not only scientific thought, but that of the public at large too. Who has not looked up at the galaxy while walking home late at night and wondered? Having said that though, the ancient people of certainly the northern hemisphere, but probably both, knew the movements of the stars and planets better than most of us do nowadays.

They knew even then, thousands of years ago, that the majority of stars seem to appear in the Eastern skies at night and travel on circular paths. They also noticed that some ’stars’ were ‘wanderers’ (we call them planets) and that sometimes they went ‘against the flow’.

They also named groups of stars that we now call constellations or even galaxies and knew that those visible in the winter were not the same as those seen in the summer.and that others were visible all year round. The average common man of 5,000 – 10,000 years ago almost certainly knew more about the movement of the heavenly bodies than the average common man of our times. (I mean men and women here, of course).

They learned how to calculate or at least locate the extremities of the sunrise and went to extraordinary lengths to mark those positions with huge stone structures, such as Stonehenge in the United Kingdom, probably to facilitate the location of certain positions of the sun or other planets or stars, which may have been important to their religious beliefs or crop cycles.

In 1609, Galileo invented the first artificial device for looking at the stars and planets. It was the first astronomical telescope and through it he was able to see objects millions of miles away that no one had ever seen before. Because of the deductions he drew from his observations, he clashed with the Roman Catholic Church and was often in serious danger for his life, so radical were his discoveries.

But humankind was not to be intimidated, and since then we have gone on to construct ever bigger and ever better astronomical telescopes through which we can even detect radio waves, microwaves, X-rays, infrared waves and gamma waves from outer space. Forty years ago, we even travelled to our Moon. and we have sent probes to eight of the nine planets in our Solar System, as well as to quite a few comets and asteroids.

Where are we going next? That decision was always up to the government of the United States and the old Soviet Union, but now there are other players in the field. What will China or India want to explore with their possibly slightly different outlook on life? Or will it be just a question of financial benefit?

The world may be in a state of flux and power may be moving from its traditional seats in the West, but it has not diminished interest in questions that scientists think can only be answered in space. These are exciting times for the science of astronomy, but then man has always found astronomy enthralling .

Astronomy For Teens.

Astronomy is a very exact branch of science, although a lot of people get involved with it when they are very young. Astronomy is inspiring pursuit that can show children about the other sciences in general. Certain astronomical subjects inspire kids and movies like Star Wars and they only increase this interest.

Our only natural satellite is called the moon. Its orbit around the Earth takes just over twenty seven days to complete. Man’s knowledge being what it is and because the moon is so close, it is the only space object that mankind has ever set foot on, except for the Earth of course. The effects of gravity between the moon and Earth causes the seas’ tides. The moon is one of the first objects that sparks a child’s interest in astronomy because it can be clearly seen with the naked eye.

Let’s move on to the sun. Earth is quite far from the sun, although the distance actually fluctuates between about 91 million miles and about 94 million miles. The reason for this variance is because of Earth’s elliptical orbit. Life on Earth is only possible because of the sun, which is our source of important elements such as light and heat. A little-known fact is that the sun contains about 98% of the mass of the whole solar system! Just think about how small a person is compared to that.

Our planet is in the galaxy called the Milky Way. Like all other galaxies it’s a very large collection of gas, dust, stars and planets. Most of the area in a galaxy is filled with nothing, only empty space. That means that most of its volume, 3,000 light years high by 100,000 light years diameter, the volume of our galaxy, is nothingness.

Our Earth is located somewhere in the neighbourhood of 30,000 light years from the very centre of our galaxy. The emptiness is broken up by over 100 billion stars. In fact, the galaxy was named for the thick group of stars in the main portion of it.

It looks like a pool of liquid, which is why it was called the Milky Way. There are four kinds of galaxies: elliptical, lenticular, irregular and, like the Milky Way, spiral.

There is a great deal of information on astronomy on the Internet that is suitable for children: it ranges from dictionaries and encyclopaedic references to programs that show the orbits of the different planets, solar systems and objects right on the computer’s monitor! In fact, there’s more information out there than a child could ever get through.
