Astronomy compels the soul to look upwards and leads us from this world to another.
Welcome!

Astronomy is an infinitely captivating subject and the oldest of the natural sciences. It is one of the few areas of science that amateurs can assist professionals and directly contribute to science.

As a science, astronomy began tens of thousands of years ago in ancient Mesopotamia. Later observations made by the ancient Chinese, Babylonians, and Greeks. They tracked the motion of the Sun, Moon, planets, and stars across the night sky. It was important to know the position of the moon and sun throughout the year for planning agriculture and preparing for winter. They were the first to devise the seasons. Astronomy has since advanced into a complex study of the laws of nature which govern these phenomena.

Astronomy is however more than simply a mapping the motion of the stars, Moon and Sun. It is now the scientific study of the contents of entire Universe, stars, planets, comets, asteroids, galaxies, and space and time, as well as its history.

If you’re starting out and looking at the sky at night, the contents of this site will take you through what you can see at night as well as some equipment advice. The tutorials cover the types of objects you can see and also illustrate some basic astronomy concepts.

 

The Celestial Sphere - Right Ascension and Declination
4th April 2008Astronomy
The most fundamental property that any astronomer needs to know is our place in the heavens and the position of astronomical objects that lie on the surface of the celestial sphere. We will look at the Celestial Sphere, the ecliptic and how to locate objects using Right Ascension and Declination.
Kepler's Laws of Planetary Motion
19th March 2008Astronomy
In 1609, a German mathematician by the name of Johannes Kepler discovered a simple relationship between the distance from the Sun and a planet's orbital period. This relationship became the foundation for Kepler's laws of planetary motion.
Good things come to those who wait. Good things come to those who work their asses off and never give up.
How far away is the Moon?
19th March 2008Astronomy
How far away is the Moon? Hipparchus first calculated the distance in 190BC using a simple method involving trigonometry and was accurate to 1,000km!
How Large is the Earth?
19th March 2008Astronomy
How large is the Earth, and how do we know that? It was the Greek mathematician and astronomer Eratosthenes who first calculated the size of the Earth, and he did it in 200 BC with a stick!
What is Cosmology
22nd December 2007Cosmology
Cosmology is the astrophysical study of the history, structure, and dynamics of the universe. The word cosmology is derived from two Greek words, "kosmos" meaning the world, and "logos" meaning knowledge or science.
Harvest Moon Rising
27th September 2007Observations
Time for a quick update, the pain and swelling from my wrist operation are subsiding now which is good, and I'm sleeping better at night which is also good.
My Second M31 and Milky Way
15th September 2007Observations
It has been a while since I have done any astrophotography, mainly due to all the clouds and lack of a summer this year!
Great Night Viewing
12th August 2007Observations
Tonight I had a very good nights astronomy, starting with my first visual of Jupiter this year.
