Phototherapy is still used to today to treat conditions such as eczema, psoriasis, jaundice, mood and sleep disorders, and some cancers. The healing power of the sun is a powerful reminder that the sun plays an important role in human health should not be avoided.
What is the Sun's magnetic field?
The Sun has a very strong magnetic field. Magnetic energy released by the Sun during magnetic storms causes solar flares. We see these as sunspots. In sunspots, the magnetic lines twist and they spin, much like a tornado would on Earth. The Sun generates solar wind. The wind is a stream of charged particles.
How fast does solar wind travel?
This travels at approximately 450 kilometres per second through the solar system. Solar wind occurs when the magnetic field of the Sun extends into space. Sol is the Latin for Sun. This is where the word “solar” comes from, which is used to describe things that are derived from, related to, or caused by the Sun.
What happens when the Sun burns all its hydrogen?
The Sun will consume the Earth. When the Sun has burned all its Hydrogen, it will continue to burn helium for 130 million more years. During this time, it will expand to the point that it will engulf Mercury, Venus, and the Earth. At this stage it will have become a red giant.
How many Earths can fit in the Sun?
One million Earths could fit inside the Sun. A hollow Sun would fit around 960,000 spherical Earths. If squished inside with no wasted space, then around 1,300,000 would fit inside. The Sun’s surface area is 11,990 times that of the Earth’s. The Sun contains 99.86% of the mass in the Solar System.
Why are sunspots darker than surrounding areas?
Sunspots are areas of the Sun’s surface that appear darker than the surrounding areas, this is because they are cooler. They form in areas of strong magnetic activity that inhibit heat transfer.

The Sun is a main-sequence G2V star (or Yellow Dwarf). The Sun is 109 times wider than the Earth and 330,000 times as massive. The Sun’s surface area is 11,990 times that of the Earth’s. A hollow Sun would fit around 960,000 spherical Earths.
What is the Sun?
The Sun is the star at the centre of our solar system. It is an almost perfect sphere of super-hot gases whose gravity holds the solar system together. The energy produced by the Sun is essential for life on Earth and is a driving force behind the Earth’s weather.
What formed the Sun?
Whereas the orbiting disk shape clouds formed the other solar system objects such as planets, moons, asteroids, and other solar system objects. High-density clouds and dust of solar nebula collected at the center of the rotating disk and hen ce formed the sun.

What does it mean, the sun has created a system where these all bodies exist and it is called the solar system. The solar system is so big and no human technology has crossed the solar system. This Sun is orbiting the center of the milky way galaxy at a speed of around 220 km/sec with these all bodies. Do you know the below interesting fact of the ...
How does the Sun create energy?
The sun creates energy by nuclear fusion of Hydrogen into Helium. Generally, it helps life on earth by photosynthesis and also responsible for climates and weather on earth, but knowing deeply about it is going to amaze you.
How did the Sun form?
Our sun was formed around 4.5 billion years ago, due to the gravitational collapse of a solar nebula. A solar nebula contains giant clouds and dust. And the gravitational collapse is the contraction process of any object due to its own high gravity .
What is the reason for the available energy even on Earth?
The sun is the reason for the available energy even on earth. In the core, hydrogen converts into helium by the nuclear fusion reaction. In nuclear fusion, two or more atomic nuclei combined and form other atomic nuclei in the presence of very high temperatures (1.5 × 107 K).
What happens when the moon comes between the Sun and Earth?

The Sun has circled the Milky Way galaxy more than 18 times during its 4.6-billion-year lifetime. The Sun is the closest star to Earth.
What is the color of the sun?
Sunlight appears yellowish, but it is actually a combination of a rainbow of colors. Solar flares from the Sun are sudden bursts of brightness that happen in places near the sunspots. Solar flares produce bursts of electromagnetic radiation, x-rays, ultraviolet radiation, visible light, and radio waves.
What are the two types of radiation from the Sun?
Radiations of the Sun are in two forms, electromagnetic (photons) and particle (electrons, protons, alpha particles , etc.) radiation. In addition to heat and light, the Sun also emits a low-density stream of charged particles (mostly electrons and protons) known as the solar wind which propagates throughout the solar system at about 450 km/sec.
What is the atmosphere of the Sun?
The atmosphere of the Sun is composed of three areas: the photosphere, chromosphere, and solar corona. The visible part of the Sun is called the photosphere. Corona is the Sun’s outer atmosphere with temperatures that range from a few thousand kelvins to a few million kelvins.
Why is the Sun closer to Earth than all other stars?
