Introduction

 

There’s a mass of things we know about space although there’s a great deal more information we don’t know. As time grows space simultaneously gets lesser and greater in mass.

Goldilocks And The Three Zones

 

The Goldilocks zone is the same distance away from the sun to earth or specifically the distance that can sustain life, or water. Earth is just the right distance away from the sun to keep life for million to billion years. 

 

Soon, as in a million years, Mars will be in the Goldilocks zone and be habitable. The nearest Solar System is Proxima Centauri B. It could have a planet in the goldilocks zone. Trappist-1 Solar System had over 3 planets that can be in the Goldilocks zone. In millions of years, the Earth may not be in the zone, because as the sun expands into a red dwarf, it may consume the Earth as it collapses in on itself.

     The Superb Supernova

 

A supernova is when a star dies, or collapses in on itself. Then it releases all kinds of gases or elements. It’s for a brief second. But if we see one with the naked eye it happened a hundred light years before we see it because only travels that fast.

Particularly, a star named Betelgeuse is almost ready to become a supernova. Betelgeuse is the 3rd largest star, a red giant Once it does we will see our sky  light up. It could have already collapsed in on itself, and we are just waiting for the light to reach us. Also, if a star collapses in on itself, and its close, we can possibly see it.

Milky Way (Not The Candy)

 

The Milky Way Galaxy has has about 200 Billion stars in it. It became its current size and shape by eating up other galaxies, and is still doing so today. In fact, the Canis Major Dwarf Galaxy is the closest galaxy to the Milky Way because its stars are currently being added to the Milky Way’s disk and our galaxy has consumed others in its long history, such as the Sagittarius Dwarf Galaxy.

The closest Spiral galaxy though is the Andromeda Galaxy a.k.a. Messier 31. It is the largest galaxy out of its neighboring galaxies, including the Milky Way. Also it is soon to become part of the Milky Way in a few billion years. It is now colliding with Messier 32.

 

 

The First Moon Of Saturn

Titan is the largest of 62 moons that is orbiting Saturn. It was the first known moon of Saturn. It is the only moon to have a dense atmosphere. The atmosphere is made mostly of nitrogen. It is made out of ice and rock. So if it has ice it can turn in to water and could inhabit life.    

 

The climate temp. is – 179°c. It has a north and south pole much like Earth. The crust of it is Ice. Like earth it has wind and rain. It could have dunes, rivers, lakes, and seas. The seas and lakes are made up of liquid methane and ethane.

Conclusion

The Universe is all of space and everything in it. As it expanded, galaxies with stars and planets were formed.

“Look again at that dot. That’s here. That’s home. That’s us. On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there—on a mote of dust suspended in a sunbeam.”- Carl Sagan
