Hi Bryce Forum

This is not directly related to Bryce but I know some of you like Space and the Universe so I thought I put a bit of What makes Stars Work. A Star Can come in Many Sizes and can be either Very Big or Extremely Small. The Sun is a 4.5 Billion Year old Main Sequece Star Yellow Dwarf Class G2. It is losing millions of tonnes of Energy as it converts Hydrogen into Helium it gives of the energy in this process of Millions of Hydrogen Bombs every Second. The Sun is Roughly 93 Million Miles away and it can still burn you eyeballs out of your head if you look at it directly. it is 400 Times Bigger than the Moon and the is 400 Times Closer to us than the Sun so when there is a solar ecclipse it more or less covers the sun and all you can see is the Corona. The Suns Surface Tempreture is 5500°C 10,000°F. The Sunspots are a warning there is going to be a CME(Coronal Mass Ejection or Solar Flare).The Sun is 99.8% of the Solar Systems Mass and Jupiter Takes up the Rest. You can fit 1.3 Million Earth Sized objects in the Sun. And the Sun is actually an average middle age Star. The Smallest Stars on the Main Sequence are Red Dwarfs and they can shine for Trillions of Years(although The Universe is only 13.7 Billion Years old so it is technically a theory.). When the Sun Dies it will Swell to Become a Red Giant and Destroy Mercury, Venus possibly the Earth too When the Red Giant Stage Ends it will shed its loose outer layers to become a tiny white Dwarf that will burn pretty much to the end of time. and when that Stage ends it will hypotheorectially Become a Black Dwarf Star. When a Red Dwarf looses it fuel it will swell to become a Blue Dwarf(also Theorectial some say it will wink out of existance). Bigger Stars like Super Giants are Much Bigger than the Sun and use their fuel up much more Quickly the Fusion doesn't end with Helium like in dwarf stars it then fuses helium into calcium, Gold, Silver iron and others I forgot. Iron is what kills them they have seconds to live once they fuse Iron they Explode in a Super Nova Leaving behind a Nebula(The sun will leave a planetary nebula nothing like Super Giant Nebula's and nothing to do with planets.) or a Neutron Star at the first Satge will be a Magnetar which will become a Magenetpulsar and then a Pulsar. The Fastest Spinning pulsar is over a million times a second. If a Pulsar or White Dwarf Entered the Solar System we would be doomed. if one hit the sun it would explode it in a Type 2 Supernova. Hypergiant Stars live even shorter lives and when they Explode in an Hypernova they leave behind a Black Hole. The Biggest Star in the Diameter is NML Cyngi at 1650 times the radius of the sun and its a Red Hypergiant. And the Biggest in Mass at 265 Times the Mass of the Sun is R136a1 and its a Blue Hypergiant. in Stars the Blue ones are the Hottest and the Red are the Coolest. Stars are not on fire they are more like Neculear Reactors they are kept alight not by fire but Nuclear Fusion. And Thats a few facts about Stars.

I hope you like it
