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. Astronomy is 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 in Astronomy and looking at the sky at night, the contents of this site will guide you through what you can see at night as well as equipment advice, observation tips and tutorials. The astronomy articles cover the types of objects you can see and illustrate some basic astronomy concepts which are important to learn. You can also find several astronomy DIY projects which you can build yourself.

 

The Physics Governing the Universe
22nd September 2008Cosmology
In this article, we will have a look at some of the important physics concepts needed to understand how the universe works.
Apparent Magnitude, Absolute Magnitude and Distance
22nd April 2008Astronomy
The apparent magnitude and absolute magnitude are two ways of comparing an object's brightness. In this example, we look at the relationship between absolute magnitude, apparent magnitude and luminosity.

Luminosity of Stars
22nd April 2008Solar Physics
In astronomy, luminosity is the total amount of energy radiated by a star, galaxy, or another astronomical object per unit time. It is related to the brightness, which is the luminosity of an object in a given spectral region. In SI units luminosity is measured in joules per second or watts.
Flux
21st April 2008Solar Physics
Flux is a term used to describe the brightness of a star and is a measure of the total energy from an object per unit area over time. Flux calculations are used to calculate luminosity, a more meaningful representation of a star's brightness.
The Magnitude Scale
21st April 2008Astronomy
The visual brightness of stars, planets and other astronomical objects is based on the visual magnitude scale. We look at this scale and how astronomers use it to measure relative brightnesses of objects in the night's sky.
Sidereal Time, Civil Time and Solar Time
17th April 2008Astronomy
There are several different systems for measuring Time. Civil time is the system we are all familiar with, however, astronomers use a different system - sidereal time which is measured with reference to background stars in the sky, as opposed to the Sun.
What is Angular Size?
17th April 2008Astronomy
You may have heard the terms arc-minute and arc-second mentioned on the TV, magazines or other websites. These are the units of measurement for angular size used in modern astronomy. Angular size is used to describe the dimensions of an object as it appears in the sky.
Parallax, Distance and Parsecs
17th April 2008Astronomy
In Astronomy, parallax is a method used to determine the distance to the closest stars. This technique for measuring astronomical distances is very important because it is a geometric method and independent of the object being observed.
