How a star is born?

How a star is born? Since the time human has started to think, they started to strive to understand nature. Our universe has always been a big part of human curiosity. Even in ancient times, man had started to assume about all the other bodies present in the universe. They must be thinking about the stars in the sky. Because of the same curiosity, humans have been able to invent so much. But the one question has always occupied the largest portion of our curiosity. how exactly star is born? and how do they die? What is Nebulae? The place where a star is born is called Nebula. A  nebula  is a giant cloud of dust and gas in space. Some nebulae come from the gas and dust thrown out by the explosion of a dying star, such as a  supernova . Other nebulae are formed, when gas on large scale spread in the space, it starts to accumulate due to mutual gravitational attraction. In those regions, a star is born. For this reason, ...

Most abundant element in the universe.

Most abundant element in the universe. No word is more simple than the universe. It simply means all, no comparison, no differentiation, no addition, no subtraction. But also the universe is the most sophisticated if we try to understand the meaning of the word. It consists of an infinite number of bodies in it, in the form of Planets, Asteroids, Comets, Stars, Galaxies, Nebulas, Blackholes etc. The universe is made up of many elements, but the elements in the most abundant quantities are mentioned here (The data is on the basis of the research till date). The Universe Most abundant elements are: 1.Hydrogen. 2.Helium. 3.Oxygen. 4.Carbon. 5.Neon. 6.Nitrogen. 7.Magnesium. 8.Silicon. 9.Iron. 10.Sulfur. Most of the most abundant elements are in the form of gases. Hydrogen is about 75% of all the elements in the universe. Helium is about 23-24% and the rest is the other elements. Most of the stars are made of Hydrogen and Helium only. Nebulas are made of dust and ga...

The Pluto - a dwarf planet

  The Pluto - a dwarf planet Had you asked anyone before 2006, which is the smallest planet in the solar system? An immediate reply would have been The Pluto . But now it is mere at the status of a dwarf planet. Now we can say The Pluto - a dwarf planet. The size of the dwarf planet is way smaller than the moon, about 66% of the diameter of the moon. Why and when Pluto lost the status of the planet? The planet is anything which is revolving around The Sun. As per this logic, Pluto should also be a planet as it used to be, but this is not the case anymore. Eris a dwarf planet was discovered in 2005, in the scattered orbital disc. The discovery of Eris led the scientist to think about the status of Pluto as a Planet. In 2006, Scientists formally defined the term Planet. Till 2006, there used to be nine planets in our solar system, but now there remains eight only. Pluto has lost the status of a planet in 2006 and got the status of a ...

What is a Satellite?

What is a Satellite?           Satellite is an object which revolves around another bigger object. Its two main types are, Natural and Artificial. Moon is the natural satellite of Earth. Similarly, our eight planets are the natural satellites of the Sun. Every planet has its own moon except Venus. A satellite stays in its orbit and revolves with the help of the balance between gravitational force and centrifugal force. Gravitational force act inwards while centrifugal force towards in outer direction. When an object takes a circular path a natural called centrifugal force acts on the body in outer direction. Our Solar System          Earth has only one Moon. For the longest period of time, Jupiter was considered to have the highest number of natural satellites but recently Saturn has overtaken Jupiter to have the highest number of natural Satellites. However, this figure also is also not final as ...

IC 1101( The largest known Galaxy)

           IC 1101( The largest known Galaxy)            A Galaxy consists of stars, a huge collection of gases, interstellar remnants, dust, dark matters etc. Galaxies are classified into a spiral, elliptical or irregular based on their formation. The largest known galaxy ever discovered is IC 1101. It is a massive elliptical galaxy. It is at a distance of 1.045 billion light-years away from the Earth, and its diameter is 1.97million light year. It also consists of the largest known black hole known to man. Andromeda is the largest galaxy in the local group. It is also the closest to our Milkyway Galaxy.     The size comparison of Galaxy IC 1101 with our Galaxy Milkyway is shown in the picture below. Some interesting facts about Galaxy IC 1101. 1. There are about 100 lakh crore (100 trillion) stars exist in this supermassive  Galaxy.  2. The Galaxy is in Virgo constellation.  3. The Galaxy was discovered in 1790 by Brit...
