Universe means unimaginably vast space which is unbounded with its dots of body's are by definition, the universe includes everything that abounds in space, and space is filled with matter which varies from the tiniest and cosmic particle to the gigantic galaxies.
Essay on Our Universe Geography Article shared by: Universe consists, constellation, in which Sun exists, is so big that from the core of constellation, light takes around 27 thousand years to reach up to sun.
The solar system which is part of Milky Way galaxy is in disc-shaped spiral form. Sun rotates round its axis from West to East.
Sun is not stationery and completes one rotation round its own axis in 25 days. One rotation of sun takes 25 days of Earth if observed from the equator while if we observe it from its poles, each rotation of sun takes 36 days.
The rotation of sun was observed by Galileo first of all. Sun is source of light, heat, energy and life on our Earth. Normally looking pale, this spherical ball of fire has 13 lakh multiples more volume than that of Earth and 3.
Pressure of gaseous material on its centre is billion multiples more than the pressure of air, Earth experiences while density of gases is times more than that of water. Temperature of sun is 50 lakh degrees Kelvin one Kelvin is equal to one degree on Celsius scale. Hydrogen in form of Plasma turns into Helium at this temperature.
This fusion gives birth to energy. The quantum of such produced energy may be imagined from the fact that fusion produced energy in one second is more than as much mankind has used on Earth till date.
This fusion is continuous process on the surface of Sun. Gravity of Sun is 28 times more than that of earth and black spots visible on sun are actually very powerful magnetic regions.
Each magnetic regions of sun is more than 10 thousand times more powerful than magnetic power of Earth. Actual size of each black spot may be lakhs of square kilometers. At corona this temperature varies from 10 lakh Kelvin to 50 lakh Kelvin.
Continuous winds blow at the surface of sun at speed of to kilometer per second and these may prove dangerous for Earth at times.
These winds have their fatal effect on Ionosphere. Solar storms disturb communication system on Earth.
Many a times, power grids get destroyed or seized because of disturbance at the surface of Sun. Optical telescope at Udaipur and Kodyekanal along with Radio telescope at Pune keep continuous watch over happenings related to Sun.
Planet is a Greek word which means, Wanderer. All the planets are spherical and are total eight in number. We can group these planets in two, that is: Inner planets are those planets which are nearer to sun as compared to others. Secondly their relief constitution includes rocks and metals.
These planets are known as terrestrial planets also. Outer planets are beyond asteroids and are constituted of gases, popularly known as Gas Giants. These are; Jupiter, Saturn, Uranus and Neptune.
The planets do not have any light of their own but these illuminate by reflecting sunlight and are visible at night.Abstract The universe is a known place to our young and sensitive eyes. Stars galaxies, planets, comets, asteroids are part of this abundant place that has an end of 8 billion years to us.
The age of the universe is still being challenged due to further understanding surrounding astronomical related elements. More scientists believe the universe is at least 5 billion years old, but other think it may be much older than that.
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before . Essay on The Big Bang And The Creation Of Our Universe - Ever since the dawn of man, we have tried to understand the world around us.
We still try to explain how this universe came to be and how we as humans came into existence.
Our Universe Our universe was created billions of years ago and no one is exactly sure of how. What will come of it in the future? Religions, beliefs, and scientists all have different perspectives of what will happen in the future to our earth and universe and they all have different views of how it all started.
Essay on Our Universe Our Universe contains billion (one billion = crores) constellations (group of stars) and each constellation includes hundreds of billion stars. Universe consists, constellation, in which Sun exists, is so big that from the core of constellation, light takes around 27 thousand years to .
