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 ...
One of the most striking examples of a supernova remnant is the Crab Nebula, found in the constellation of Taurus. Sometime between April and June of 1054, a so-called "guest star" flared into being, visible to the naked eye where no star had been discernible before. Two years later, ...
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 ...
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...

A 3D illustration of a neutron star in the nebula. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. After such an outburst, the cores of these former stars compact into an ultradense object with the mass of...
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 ...
