Astronomy can be defined as the branch of science that deals with the study of natures and motion of celestial bodies like stars, planets and galaxies. There are yet different definitions for Astronomy. This includes the study of matter and objects outside earth's atmosphere and having their own physical and chemical properties. Some different views include -Astronomy is the study of everything. This is because astronomy is the study of universe and everything is part of the universe.

One can say that all these definitions are correct and hence there are many sub fields within astronomy. Cosmologists, Astrometrists, Planetologist, Radio astronomers, Mathematical astronomers are some among these sub divisions. Cosmologists study universe as a whole including its origin and beginning. Planetologists do study about all those planets with in the solar system and those orbiting distant stars. Astrometrists calculate distances connected with universe. Again Radio astronomers use radio telescopes to study the universe. Numbers, calculations and statistics are used by mathematical astronomers in order to explain universe.

We can't say that astronomy is a stand alone subject. It is a combination of different fields. These fields include mathematics, geology, chemistry, physics, geology, biology. Physics can be said to be as one of the most integral part of astronomy. That is why some of the astronomers are known as Astrophysicists. Astronomy can be said to be the oldest science. During the early age, astronomers were priests and holy men, who tried to fix the puzzle of the universe. They tried to determine planting cycles and celebrations. Astronomy theories where first developed and introduced by ancient Greeks. They made out theories about the universe design as a whole. There were many astronomers who proved them to be great astronomers. Later many of the facts provided by them proved to be wrong, as technology came forward with a helping hand. Some of them include Ptolemy, Copernicus, Galileo Galilee, Johannes Kepler etc. but one fact is sure that with out the contributions of all those greats the facts known today could not have reached upon.

Again it can be said that astrology is the study of cosmos. An attempt to understand the history and make up of universe can be termed to be as astronomy. An unlimited area of fields is covered under astronomy. They include stars, nebula, planets, sol, star clusters, galaxies, dark matter, black holes etc. each of these can be again divided into multiple topics. Research is done in the whole electromagnetic spectrum. This includes ultraviolet, visible, x-ray and infrared. Thus it really covers lots of things when it comes to astronomy.

Interesting Astronomy Facts and its relation with other branch of science

The astronomy and its facts directly concerned with other science branches. Evolutionary science and chemistry are the prominent beneficiaries of astronomy facts. The origin of planets rather universe is the key stone of evolution. Biology scientist would be greatly benefited in order to define the origin of life if the origin of universe has been discovered. Chemistry scientists are closely associated with the astronomy while they define the properties of a matter.

The history of astronomy always projects some visionaries who discovered a lot of astronomy facts and published them to the world. "The course of science has changed often due to the new discoveries by utilizing new tools" says Patrick Brady. We all are interested in the facts which lead the science; especially anything related to astronomy. Here we discuss some basic astronomy facts.

A light ray needs to travel 8 minutes to reach Earth from the Sun. If you are looking at a star, for example Andromeda galaxy, it is 2.3 million light year away from the earth. So, when you watch andromeda galaxy now, you are watching the galaxy as it was 23 lakh years ago! Even if anyone is able to travel with the speed of light, they would take almost 10000 years to cross our galaxy. Such astronomy facts give us an idea about how big our universe is!

Galileo believed that Saturn had ears when he first watched Saturn through telescope. However, years later man found that it was not ears but dust particles. If we put Saturn in water, the planet would float on the water; because the density of this planet is lesser than that of water.

Do you know the weight of Jupiter? It is heavier than all the other planets of the solar system put together. Some astronomy facts are astonishing as well as funnier than anything. If you look at the sky at night time, you can only watch around 3000 stars. However, there are 100,000,000, 000 stars even in our galaxy.

The previously discovered astronomy facts help an astrophysicist to define the new theories and discoveries. It is a fact that astronomy is considered as the older science which is known to mankind. Greece and India were the center for astronomy wisdom in ancient time. They discovered lots of astronomy facts and recorded it. Astronomy is always owed to lots of ancient amateur astrophysicist who recorded hundreds of astronomy facts without having any sophisticated equipments but simply observing the universe.

Astronomy news dissemination: What are the practical approaches?

We all read or watch news about astronomy daily. Nowadays newspaper industry is facing a problem that they striving hard to keep their subscribers. People are searching for other options to up to date the news without spending money. In 1970, the average newspaper subscription was 1.3 however in 2000 it became .53. So, if we need to spread the astronomy news to the people, we have to adhere with the new technologies and new options because the people are busy.

The best way nowadays to spread the astronomy news to the readers is internet. Blog is a powerful medium to deliver the news. The main adaptability of blog is that it is easy to read and understand. Just search and gather the news related to astronomy and write it in your own words, then just publish it. The readers can communicate with the blogger. This gives more acceptances to blog. Astronomy news readers are interested in reading such blogs. The blogs redefine the so called 'frame' of journalistic language.

Another best way to spread astronomy news is newsletters. E-news letters are fine option for readers who are not a 'voracious' reader. This method allows them to get information of a whole week or a particular interval in a concise form. There are hundreds of astronomy websites which enable the readers to enjoy this facility.

The astronomy news can also be disseminated through the planetariums and the various research centers. They can conduct exhibitions and provide the people with notices and pamphlets. The planetariums are the places where the people can experience the feeling of astronomical observations and these are the best places to provide them with the astronomy news. The news can be provided with attractive photographs and also with guidelines for the people to observe the sky.

Documentaries, short films etc. are the best ways to propagate the astronomy news. The films make the viewer to watch the whole show and make them interested in the field of astronomy. The short films can also be posted in the websites and these can also be shown at the exhibition centers. The main attraction of this method is that the people can grasp the themes without reading and can comprehend the astronomy news well.

The research centers can also form an 'astronomy news club' among the lay people and provide them with the news through weekly or fortnightly alerts through e-mails or through newsletters. This can sustain with the public donations and can be a good method to spread the astronomy news.
