Yellow Dwarf Star, Our Beautiful Sun.

Trying to find a subject beginning with"Y" was looking like quite a challenge when I got to work this morning but I still had to deal with the letter "X" so I didn't spend too much time thinking about it. After publishing the "X" post I had to get back to work, things were a bit hectic. Later on things calmed down and I had a little time to search for some "Space" subject beginning with the letter "Y". The first thing that popped up was Yellow Dwarf Star and lo and behold, Our sun is a Yellow Dwarf. I've heard this before so was not too surprised about the fact and decided this was the star I wanted to write about, I haven't written about our sun yet so here goes.
Believe it or not our sun is one of the brightest stars in the Milky-way being brighter than about 85% of the stars. Most stars in the Milky-way are known as red dwarfs with only about 5% of the stars in our galaxy being bigger than the sun. One wonders why they would call it a dwarf if almost everything else is smaller than our sun. It's known to be a very hot and young star with temperatures reaching as high as 15.7 million degrees centigrade in the center. The light, and of course the heat from the sun takes just a little over eight minutes to reach us. We are quite a long way from the sun, for which I'm actually grateful, 150 000 000 kilometers.
The sun has this eleven year cycle it goes through with sunspots and coronal mass ejections appearing when it's most active and being almost uniform when it's at it's most peaceful. We are told that the sun comprises mostly Hydrogen which is changed into Helium through nuclear processes. This process which creates sunlight and warmth, which is completely free by the way, is what has sustained all life on this little world ever since God created it. Thank you Lord.
People have known just how important the sun is for a few years now, they have even built entire societies and civilizations worshiping it and in some instances gotten into a whole lot of trouble for that. God got quite annoyed with the Egyptians, the Israelites and a few other wayward peoples. Worship God, not the sun silly people.
There is a very well written and interesting article in Universe Today about the sun that is well worth taking a look at.
Well it's once again time for me to get back to work. Blessings to everyone and have a fantastic weekend, Geoff.

  1. Great article about our sun! Seems I remember in the recesses of my mind learning it was a "dwarf" in school. God's orchestration of his creation is beyond our comprehension. For all the information science has given us, for all the knowledge we have, it is but a drop in the bucket compared to the reality. But we shall "understand it better by and by."

    Man often falls into the trap of worshiping the creation over the creator. Now days we see man celebrating himself and and any debauchery that comes to mind instead of recognizing the precious gift we have been given.
