What is Sun?

The sun is a star. It is a huge glowing ball of hydrogen and helium gases. The sun is mainly made up of hydrogen gas which is turned into helium gases through nuclear process called 'fusion'. The energy thus released is being scattered in space as sunlight.
The sun looks much bigger and brighter to us then the other stars, because it is much closer to the earth, when compared with other stars.
The sun is about 149.6 million kilometers away from the earth, while the next closer star, Proxima Centauri, is about 2,50,000 times further away.
The sun has a diameter of 1.4 million kilometers. It is about one million times bigger then our planet Earth. More then 1,000,000 globes with the size of the earth, could fit inside the Sun.
Almost all the light and heat of the Sun are emitted from its surface. So the Sun's surface is also called 'Photosphere'. The average temperature of the photosphere is 55000C.
All the planets in our solar system orbit the Sun, and in turn, our solar system, orbits the centre of our Galaxy -The Milky Way. It takes about 225 millon years, or one cosmic year, for the Sun and the eight planets to orbit the Milky Way once.
The gravitation of the Sun is far greater that of our earth. The Sun's force of gravity is 28 times stronger then that of earth's. The Sun emits many kinds of radiations, in addition to heat and light. Radio waves are one among them. Scientist learn a lot about the Sun by studying about these waves with radio telescopes.
Scientists believe that after a hundred billion years, the Sun will shrink to become a white dwarf star, which will eventually fade into the cool, dark Universe.

Sun

When did the Sun originate?

The Sun was born from a solar nebula, a vast cloud of gas, dust and debris. The birth of sun may have occurred 4600 million years ago. Gradually, the core of this huge cloud contracted into a proto star. This proto star shrunk, and become the Sun. The planets and their moons were formed much later, from the leftover matter of the nebula. Many billions of stars were already there, before the birth of the Sun and many more followed.
The Sun is 149.6 million kilomters away from the earth, and it takes more then 8 minutes for its rays to reach us. The sun's gravity keeps all the planets orbiting around it, from flying off in a straight line into outer space.
Different Layers of The Sun
The sun have several layers. The sun temperatures and the pressure increases as we move towards the centre of the sun. The photosphere is outer layer. The temp. of the photosphere is 60000C.
The core is the hottest part of the sun. As the name suggests, it is the central part of the sun. Here the temperature is 14,000,0000C.
The core is surrounded by the radiative zone. In this zone, the solar material is hot and dense enough hot for heat to be transferred from the core through thermal radiation. The convective zone surrounds the radiative zone.

Sunspots And Sun Flares

Sunspots are the dark patches seen on the visible surface of the sun. Sunspots are caused by a strong magnetic field which blocks the outward flow of heat and energy from the core to photo-sphare. The sunspots are relatively cooler regions on the sun's surface, but they still have a temperature of about 40000 C.
Sunflares are the violent eruptions on the surface of the sun. Huge quantities of heat and energy are released in these eruptions. They are caused by the collapse of magnetic field around the sunspots. At times, the gigantic flame may shoot up to the height of 100000 kilometers. Such flames are known as 'Solar Promenences".

Sun Pillar

In most places on Earth, a lucky viewer can see a Sun-pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually these ice crystals evaporate before reaching the ground. During freezing temperatures, however, flat fluttering ice crystals may form near the ground in a form of light snow, sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun-pillar.

Sun Pillar in British Columbia

Notice the spot of light above the fourth boat from the left? That's a sun pillar, a narrow column of light that appears to beam directly upward (and sometimes downward) from the sun. Pillars are not vertical rays. Rather, the distinctive features are produced by light glinting off ice crystals in the atmosphere. Sun pillars are often longer and brighter after sunset. Doug Farmer took this photograph on June 21, 2014, while looking out over English Bay in Vancouver, British Columbia.

Q. hermoso cielo,que bueno es nuestro DIOS al regalarnos esta maravilla de poder ver sus grandes maravillas!


Ans. Any sane, logical person would be able to look up and know the skies are being heavily sprayed and manipulated at this point. And as it continues to get worse and spiral out of control, anyone who vehemently opposes the geoengineering reality is either insanely IGNOREant or a paid shill choosing pieces of paper with no real value over humanity and it's vast potential. I mean really...just how blatantly severe does it have to get?
