From the name, a reflection nebula is an interstellar cloud of dust particles that reflect light from a nearby star. This means that as opposed to an emission nebula that gives off various colors, a reflection nebula is unable to give off its own light, but has to rely solely on the light given off […]
The Sun, Moon, stars and other celestial objects are beyond the reach of any instrument that can be used by observers here on Earth. Measuring the distance of a celestial object from the Earth might seem to be complicated. But measuring the distance of these remote entities have been simplified by the concept of parallax.
There are many terms in astronomy, and there is no doubt about that. One of which is the concept of Obliquity, more commonly known as the axial tilt. The angle between a certain rotational axis of an object and the specific perpendicular line in regards to the object’s orbital plane is better known as its
A group of up to a thousand young stars that were produced from one giant molecular cloud held together by joint gravitation is better known as an Open cluster. It is found in irregular and spiral galaxies where there is active star formation. It is sometimes referred to as Galactic clusters, because they are almost
The Omega nebula is a star-forming region in the constellation of Sagittarius. It is also called the Swan Nebula and the Horseshoe Nebula, as it takes the shape of both a swan and a horse shoe. It was discovered by Swiss astronomer Philippe Loys de Chéseaux in 1745-1746. It is just one of many galactic
The Nebulae and Clusters of Stars NGC, or New General Catalogue is a list or catalogue of deep sky objects. It was first compiled by a person named J. L. E. Dreyer in 1888, using observed data from various astronomers, among them William Herschel and his son, and James Dunlop. Dreyer was commissioned by the

Most celestial bodies can be observed as entities resembling a definite shape when the proper equipment is used. The Sun, when viewed under a solar filter resembles a great big ball without the harmful rays. Most of the stars can be viewed the same way, where it can be seen as a sphere. However, numerous
In space or astronomy, there are different stars, like our sun. Other stars may be bright, dim, big small and other physical characteristics. And the arrangement and study on what types of stars are in space is called Stellar Classification.

Stars are decorative fixtures in the night sky. Constellations make great wallpaper as it resembles an artwork crafted in the vast universe. But within these bodies are revelations of mystery, beauty and creativity. The vast number of stars in the universe, there are binary or multiple systems. These are essential for astronomers to be able
If you feel bored observing the sky on your own or would like the company of other people who share the same passion, you can organize a star party, the gathering of astronomers and fellow star gazers. Some star parties may be a whole night affair, such as the ones you may organize with your
