1) If you consider the manner in which the planets are named in the solar system, then the sun’s name would be “Sol” which is the root of the word “solar”. 2) The sun is a star which is neither a solid or a gas but is made of something called plasma. 3) The fusion that creates the energy the sun provides takes place in the core and it takes 170 thousand years for it to make its way out and radiating into space. 4) The sun has an eleven year cycle in which all kinds of activity such as sunspots, flares and solar storms peak and can sometimes disrupt things here on Earth. 5) It is estimated that Earth has only 5 billion years left before the sun depletes its resources and turns into a red giant and fries all things on Earth to a cinder. The image was taken from the SOHO solar observatory. This is the first spacecraft to take advantage of what is called a “halo” orbit around the sun. This involves orbiting a spot called the Lagrangian point which is a spot in between the Earth and Sun where the pull on the object is equal on each side. This means that SOHO actually orbits a space occupied by nothing, and follows inside the orbit of Earth. The advantages of this position allows SOHO to observe the sun uninterrupted by not having to pass behind the Earth which has been an issue with every previous mission to observe the sun. IMAGE NOTE: What is shown in the image above is in ultraviolet light. I make an effort to not use images in false-color and favor visible light, but the sun cannot be imaged in this way for any kind of detail (other than sunspots). So, in the case of suns and stars… I make the exception.
