Tell me what u know and feel about the sun, moon, stars, etc?

Question

basically space outside our earth's oxygenated atmosphere!

Answer 1

The sun or our star is a middle aged star that produces light and energy for Planet Earth. The Moon or Luna is our natural satellite that was once part of Earth til a large body the size of Mars slammed into Earth in it's early stages and spit out tons of molten rock into space til it formed the moon. There are billions of stars in this Galaxy and billions of galaxies in this universe making more stars that grains of sand on Earth. Stars go through certain phases. From white dwarf to red giant. Stars burn more energy the more they age and eventually burn out to a small single core the size of Earth then slowly fade away leaving the system in darkness. Some larger stars don't just burn off their energy when they die. They explode into supernovas then become black holes that suck anything into it. Including light. Stars are born out of the nebula's formed from supernovas and as gravity increases and bodies collide planets and moons are formed.

Answer 2

Here is what I know:

Normally sized Stars:

The Sun, and all stars, are basically massive burning balls of gas. They are incredibly dense because in order to fuse hydrogen in the core it needs to be dense. All stars, once the reach the end of their main sequence stage and start to run out of hydrogen bloat out so that the are many times larger than they were before, but with the same density. They are now called Red Giants, which are cooler and burn less brightly. This process is quick in astronomical terms, taking only millions of years. Once it becomes a red giant, the hydrogen is gone and the star starts to fuse helium. Once this runs out, the stars outer layers drift away leaving only the core and some surrounding gas. This is now called a White Dwarf, and it burns with little heat and light.

Massive Stars (3-50 times the size of the Sun):

The beginning phases of these stars are exactly the same as smaller stars, except instead of taking billions of years to run out of hydrogen it only takes millions. Once hydrogen runs out, it bloats out once again to form a Red SuperGiant.  Once this phase ends, the star collapses in less than a second and explodes, forming a supernova. If the core survives the explosion and is big enough, a black whole will form. A common misconception is that our star will explode or form a black whole. But it will not. Our star is way to small to do either of these two.

The Moon is a relatively small object orbiting the Earth. It is made of rock, and every year moves an inch away from the Earth. It has no atmosphere or magnetic field, and cannot support life because it is lacking essential materials.

I hope this helped, message me with anymore questions.

Answer 3

While we still sit here on earth, I consider the heavens aptly named. It is the abode of gods waiting for us to join them. One night changed my perspective. I camped out away from city lights and disturbances, and I saw the heavens. Luckily there was no moon that night. The Milky Way was like a shimmering band of silver and the whole sky had crushed diamonds strewn about. There were so many stars, I had a hard time finding simple constellations. Then the sun came up and concern of this earthly life continued.

Answer 4

the sun is a small star, the moon reflects light from the sun, stars are huge burning balls of gas and undergo nuclear fusion in which they at their core(billions and billions of degrees) fuel their life

when this fuel dies out the star collaspes because gravity pushes it in and it will supernova

and the earth's atmosphere is 60% nitrogen i believe

it's only 21% oxygen

Answer 5

As a professional astronomer, what I know about the rest of the Universe would fill several books, far too much to list on here.  If you want to learn more, I suggest you visit your nearest library.  They should have plenty of books there.
