Navigate in Space

Kia Ora readers,

Welcome back to my blog. During hurumanu 3, we are given a question about navigate in space. These questions that we have to search and find out information about it. We must include an explanation about the information we found.  

Here are the questions that we must find the answer, and the answers that I found:

1. What is a solar system?

- A solar system is a consist of a star, sun and a objects that is affected by its gravity. It includes planets, moons, asteroids, comets and a meteoroids. Solar system is a smaller than a universe or a galaxy. 

2. What is the milky way an example of?

- Galaxy is our solar system that is part of. If we lived in an elliptical galaxy instead in earth, we would most likely to see the stars of our galaxy that spread out all around the skies. 

3. What is a star? Describe a Nebula. 

- A star is an astronomical object, it is a luminous ball of a gas. It is mostly hydrogen and helium that is held together by its own gravity. The nearest star in Earth is a Sun. Nebula is a cloud of dust and a gas that is occupying the space, that is between the stars. Nebula is basically made out of dust. 

4. How do stars die?

- A stars dies because the  enervate their nuclear fuel. A enormous stars use up their hydrogen fuel rapidly. At one point that there is no fuel left, the stars collapses, the other layers shatter as a 'supernova'. 

5. Is there an up and down in space?

- There's an up and down in space. "Down" is directly, the direction gravity is basically pulling you, and "up" is just an opposite direction. Gravity is a centrally attractive force. If it's "going down" it means falling or being pulled.

6. How can stars be used to navigate?

- There are two ways that these stars are used by the navigator. The first way to navigate the stars is to obtain a line of a position by using an observation and those techniques of celestial navigation. 

Bonus questions: Find 3 facts about a Black Hole - What does the word "spaghettification" mean? 

In NASA, the recent years, they found a fascinating objects in space. 

- A black hole is a region of a spacetime. It's a black hole where gravity are so strong, that nothing can even escape from it. 

- A spaghettification is an an object that would be stretched and ripped apart by a gravitational forces on falling into the black hole. 

Thank you for reading my blog. I hope you learn something new, please give me some helpful, thoughtful and a positive feedback. And I will see you all next time, goodbye.
