SOLAR FLARES & SOLAR WINDS Volume 1, Issue 1: By Jesus & Nayla

What is a solar flare? A solar flare is a sudden flash of increased Sun's brightness, usually observed near its surface.

What causes a solar flare? When magnetic energy that has built up in the solar atmosphere is suddenly released.

How do solar flares affect life on earth? Solar flares produce high energy particles and radiation that are dangerous to living  organisms. 

What are Solar Winds? Solar winds are a stream with charged particles that are released from the sun. This is called the Corona. Solar Winds are made of plasma.

What effect does the solar winds have on earth? The solar winds affect the solar system and helps  sun produce light to earth.  


The Aurora Borealis The Aurora is ​a natural electrical phenomenon that usually looks like  colorful lights in the sky, usually near  the northern or southern magnetic  pole. The Aurora is caused by the Sun  sending small particles to the Sun.  Earth has a ​ protective magnetic field that shields us from most of the energy and particles that are being shot at us. There is a constant streaming solar wind and solar storms. During one kind of solar storm called a coronal mass ejection, the sun pushes out a huge bubble of electrified gas that travel through space at high speeds. When solar storm comes toward us, the energy and small particles move down the magnetic field lines at the north and south poles into Earth’s atmosphere causing the lights around the north and south poles.

What Are Sunspots? Sunspots are darker, cooler areas on the surface of the sun in a region   called the photosphere. The photosphere has a temperature of 5,800 degrees  Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark  only in comparison with the brighter and hotter regions of the photosphere  around them     


● Sunspots are actually fairly bright, but they appear dark because the rest of the Sun is so much brighter.  ● Solar flares are often followed by a large ejection of plasma from the  surface of the Sun called a Coronal Mass Ejection (CME). 


Sun Structure

The sun is made up of 6 different parts. It includes the Inner core, Radiative zone, Convective zone, Photosphere, Chromosphere, and Corona. Inner Core-Solar energy is produced at the center of the Sun, where temperatures reach 27,000,000 degrees F. It is in the core that nuclear fusion takes place , releasing enormous amounts of energy that makes the sun shine. Radiative Zone- Energy from the core slowly rises in the radiative zone. It takes the energy about 1 million years to travel out the radiative zone Convective Zone- Convective zone carries energy to just beneath the Sun’s Surface Photosphere- The photosphere is the visible surface of the sun, where the temperature is 10,000 degrees F. This is the part that gives off light. It takes 8 minutes for this light to reach earth. Chromosphere-The chromosphere is a thin layer of gas above the photosphere. Along with the corona, it forms the sun’s atmosphere Corona- The corona is a thick layer of gas above the chromosphere. It extends for millions of miles around the sun. The corona is the outermost layer of our local star .
