What Are The Different Types Of Galaxies?

 HELLO GUYS,


I will be defining what are the types of galaxies.





 Galaxies comes in all shapes and sizes, but astronomers divide them into just a few main types. More than half of all galaxies are elliptical, named because of their egg like shape. They are made of large numbers of old, red stars and galaxies are spiral in shape, like the Milky Way. Old stars are packed tightly in their centres, while new stars are continually being born from the large amount of gas and dust in spiral arms. Some spiral galaxies are classed separately because their nucleus is elongated into a bar. The bar is made of stars in motion, and the spiral arms extend from the ends of the bar. Some galaxies cannot be classed as either spirals or ellipticals because they have no recognizable shape. These galaxies are called irregulars, and are full of gas in which new stars are forming.

The Book of Invention: The Jet Aircraft

Image
  In 1939, World War Two began in Europe. This war would last for almost five years. In Germany, Hans von Ohain designed and installed a completely new type of engine in an aircraft, an engine which would enable the aircraft to fly at a truly high speed. This was the first jet engine, pushed forward by air which was first sucked up and compressed, and the exhaust gases expelled at great pressure. Two years later, quite independently of von Ohain, an English engineer, Frank Whittle achieved the same results. But the first people to install the new motor in an aircraft were the Germans. Their Messerschmitt Me 262 , used during the last stages of the Second World War, gave the best performance.                 By the end of the War, jet engines had begun to be used in passenger aircraft, too. Now, people could fly at higher speeds and so complete their journeys within an unbelievably short time. Passengers tr...

How The Solar System Was Formed

Image
  Hello Guys , I will be telling how the Solar System was formed. Our Solar System formed from the force of an exploding star. When some stars reach the end of their lives, they can explode into a supernova, sending shockwaves of energy deep into space. Roughly 4.6 billion years ago, a shockwave from a supernova, travelling at 30 billion kilometers (19 million miles) per hour, hit a cloud of ice, dust and gas. The force of the impact caused the cloud to flatten and rotate. From the spinning disc, our Solar System began to form
