Formation of black holes

Hello friends! In my previous blog you know about formation of stars. In this blog you will know about black holes. A illustration of black hole Image source: Wired A black hole is generally a region in space with a very high gravity from which not even light can escape. It has a high mass and a high density and a high gravity. Formation of black holes A black hole is most commonly formed when life of a massive star ends. A star must have 2.7, 3.0 or 3.2 solar masses to form a black hole. If it does not have the required mass it will turn into a white dwarf. Recommended:  Formation of Star A star burns on hydrogen, the force applied by heat and radiation oppose the gravity keeping the star balanced. But, when star had used all its hydrogen, the force of radiation becomes weak and gravity of the star makes the core collapse. The point at which the matter of star collide is called singularity. As the matter collide its mass at the center increase which increase the

Hello friends, You might have seen a night sky with beautiful shiny objects known as stars. They look beautiful, but have you ever thought that how they are formed and how much it takes to form them. Today in this blog I will tell that how are they formed. Starting material (stellar nurseries) Stellar Nurseries (Vast molecular cloud) Image source: Wikipedia Stellar Nurseries also known as Vast Molecular Clouds are the starting material for a star to form. They have a large amount of stellar dust and almost 70% of hydrogen and some helium and other materials. These are called Molecular  cloud because most of the hydrogen is in the form of molecules eg. H 2. These clouds collapse due to any type of gravitational disturbance caused due to a nearby supernova explosion. This lead the particles to come together and form the cores. As they are denser they have gravity which pulls more matter toward itself and gradually increasing its mass and gravity. Once the gr

Emission Nebula

Welcome to my new and first blog which I have created just now and the name is emission nebula. The name looks like something which is not so common. You might be thinking that what will happen and what type of information you will get from this blog? You will get all the information about science and technology from a simple curcuit to nuclear science, everything. You will get it more clear after reading the posts. This blog is going to be for everyone who is interested in the Information Technology. We will try our all to help you learn many things. So share the contents if you like them. So get ready to welcome our blog. Please note that the information provided is for educational purpose only and we are not responsible for any damage caused to anyone or any misuse of information.
