Areflection nebulais adark nebula. However, it is visible because light from a nearby source is reflected off it, hence its name. The source of the light could be either something behind it, another nebula or a star. A well known Reflection Nebula is theWitch Head Nebulawhere it is refle...
Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off by a star as it collapsed to a white dwarf. (Image credit: NASA, ESA, J. Hester, A. Loll (ASU)) Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a ...
TheOrion Nebulais an emission nebula and star-forming region. It is the most active star-forming region in our Galaxy, and can easily be observed up-close with a small telescope. The Orion Nebula is a perfect example of a star-forming region or “stellar nursery”. Planetary Nebulae When ...

An example of a star-forming region and one of the most famous nebulae in the sky is the Orion Nebula.The Orion nebula is the most active area of star formation in our galaxy.Although it is visible to the unaided eye,it is only a vague glow.Through a telescope, the extent of its ...
What is a Star? It's a cloudless night and you're sitting outside, looking up at twinkling lights in the dark sky above you. You wonder about those stars and what they're made of. People thousands of years ago wondered the same things, and now we have some pretty cool answers to ...
When a star reaches the end of its life, it releases most of its mass back into the interstellar medium. This is done either through the formation of a planetary nebula or a supernova. In this way, stars produce and distribute heavier elements such as carbon, nitrogen, and oxygen in the...
A stellar nebula is a cloud of superheated gases and other elements formed by the explosive death of a massive star.Stellar nebulae emit brilliant waves of infrared light generated by dust particles within the cloud. The cosmic objects known as nebulae, from the Latin for cloud, serve as the...
Some say it is a super-star, a collection of bright stars or a super-black hole. The centre is commonly known as a supermassive black hole. The centre of the Milky Way is so far away that we have not yet been able to determine what is there. We know that we are in the suburbs ...
