Stars
Stars are cosmic energy engines that give off heat, light, X-Rays, and other forms of radiation. Stars are composed mostly of Gas and Plasma. That basically means it’s a giant super heated ball of gas, plasma, and radiation particles.
Some stars always stand out from the rest when looking into the night sky. This is because of their brightness, color, or size. Size is ranged from dwarfs to supergiants. The star Aucarinae is a monster compared to our star/ the sun. If you looked at a scale of our sun and Aucarinae, you wouldn’t even be able to see the sun. Then there's BeetleJuice. It’s bigger than Aucarinae, but it’s no match for the biggest star ever found, R136a1. It’s about 8,700,000 times the brightness of our sun, and is 265 solar masses. (one SM equals the weight of our sun)
When stars as big as our sun are about to explode, their core becomes so hot that rare elements are made. Gold, silver, and platinum. But before the elements are made, the star will swell up to 1,000 times it’s normal size. and destroy everything around it. After the explosion, the star will leave behind it’s core, called “White Dwarf.” However, when stars much bigger that explode, they leave something else behind. It leaves behind it’s core, but it’s a purple color, and the density is so strong, it would suck the iron right out of your blood. It’s also spinning with giant beams of light coming from its north and south poles. But from that explosion, elements essential for life, erupt from the star. And finally, when stars bigger than that explode, they leave behind one of the most destructive forces in the universe, Black holes.
We are very lucky that our star, the sun, is the size it is. If our star was Aucarinae, it’s would be impossible for us to live here. This is because of the Solar wind. When Solar Flares come off a star and crash together, it creates the Solar wind. It’s a form of radiation. It would destroy us if Aucarinae was our star. The bigger the star, the deadlier the Solar wind.

The R136 Star cluster was once thought to be a hyper giant star of about 1500 solar masses, 30 times as brightness as our star, temperature of 55-60,000 K and about 50 million miles in diameter. It also contains the largest star ever found, R136a1. There are 12, very massive luminous stars in it's core. All 12 stars have close temperatures, and are rounded to 37 - 76 solar masses. There are three very luminous stars that dominate the core: R136a1, R136a2, and R136a3. The star R136a1, is the biggest star ever found.

This is the Orion Nebula. It's one of the brightest nebulae, and is visible to the naked eye in the night sky. It is rounded to be about 24 light years across, it's 2000 times the mass of our star, and it's frequently referred to as the Great Orion Nebula. The Orion Nebula has some of the biggest stars in all the nebulae.
