The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
SUN Behavioral Columbus is a 144-bed psychiatric hospital located on the north side of Columbus. The hospital provides a full continuum of specialized care, including inpatient and day hospital services, for those suffering from mental health illness and substance use disorders.

The Sun is all the colours mixed together, this appears white to our eyes.The Sun is composed of hydrogen (70%) and Helium (28%).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.Sunspots
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.
Solar Flares
When the magnetic fields near sunspots cross, tangle or are reorganised, an explosion of energy can be released. Intense solar flares can interfere with radio communications on Earth.

Learn about the Sun, the star at the centre of our solar system, its composition, temperature, lifespan, and features. Find out how the Sun affects Earth and other planets, and explore its history and future.
- Composition. The sun is made up of a blazing combination of gases. These gases are actually in the form of plasma. Plasma is a state of matter similar to gas, but with most of the particles ionized.
- Electromagnetic Radiation. The sun’s energy travels to Earth at the speed of light in the form of electromagnetic radiation (EMR). The electromagnetic spectrumexists as waves of different frequencies and wavelengths.
- Evolution of the Sun. The sun, although it has sustained all life on our planet, will not shine forever. The sun has already existed for about 4.5 billion years.
- Sun’s Structure. The sun is made up of six layers: core, radiative zone, convective zone, photosphere, chromosphere, and corona. Core. The sun’s core, more than a thousand times the size of Earth and more than 10 times denserthan lead, is a huge furnace.
Jun 20, 2024 · The Sun wields a huge influence on Earth. Its gravity holds our planet in its orbit, and solar energy drives the seasons, ocean currents, weather, climate, radiation belts, and auroras on Earth. The solar wind, a flow of charged particles from the Sun, constantly bombards Earth’s magnetosphere, a vast magnetic shield around the planet.
Jan 22, 2013 · Learn about the sun's interior, atmosphere, and solar wind, and how they produce visible light and magnetic fields. Explore the sun's zones, layers, and phenomena, such as sunspots, flares, and coronal mass ejections.
