How could you prove how to discover more galaxies or planets? (Alycia)

Nobody has been able to answer this and find more not even scietists! Even so, this question brings up some creative theories!For many years scientists have studied our own solar system. But until the last few years, we didnt find any other solar systems.Well, the reason is that planets around other stars are really hard to find. Planets shine only by the light they reflect from the star they orbit, and they don't reflect much light at that.

How can you record/chart the temp. and colors of planets?(Alycia)

Link to an example of a graph. *https://www.e-education.psu.edu/astro801/content/l4_p2.html*


What color is the light emitted by the sun? If you look up in the middle of the day, you might say something like white or yellow. Later, during sunset, you might tell me it's red. The real answer is that the sunlight is a mixture of a lot of different colors! All of the ones we just went over and lots more.If you've ever used a prism to make a rainbow out of sunlight, you created a spectrum, an arrangement of light according to wavelength in this case, of visible light.

How are the sun and moon related?How are they different list 3 reasons for each(Alycia)

Similarities

1.The sun is 400 times bigger than the moon,but the sun is also 400 times furtherer away from the moon.

2.The sun and moon pull earth the same direction.

3.The sun and moon both give earth light,not as much but they both give off light.

Differences

1.The sun is a gas giant .

2.The moon is a barren piece of rock.

3.The sun directly gives off light.

Explain what happens when a comet is formed.(Alycia)


A comet is an icy body that releases gas or dust. They are often compared to dirty snowballs.Comets contain dust, ice, carbon dioxide, ammonia, methane and more.Astronomers think comets are leftovers from the gas, dust, ice and rocks that initially formed the solar system.

Who discovered that earth was not circular but spherical? (Alycia)

It may seem round when viewed from space, but our planet is actually a bumpy spheroid.

Describe how lightyears are used to measure distance and sizes in the universe.(Brianna)

they reach through the universe, by how long it is.

List 3 types of galaxies or ones that exist right now. (Brianna)

  • Elliptical,Spiral,and Irregular.

Define/describe 3 components of the universe. (Brianna)

Planetary Systems

Planets and Their satellites.

Asteroids, Meteoroids, comets, and interplanetary dust.

How could you describe our galaxies temp./colors? (Brianna)

To Study The planets temperature by looking at the glowing color.

What facts are most important about the moon that we need to include?Include at least 4 facts. (Brianna)

1. The Moon is not a Planet, it is more of a Satellite for Earth.

2.The Moon has no global magnetic field.

3.The surface area of the moon is 44,658,000 square miles or 9.4 billion acres.

4.From Earth, we always see the same side of the moon; the other side is always hidden.

How to advertise the origins of the galaxy?(Riley)

By putting in a graph of which is cool or a hot temperture and through stellar radiation pressure.

How are the wavelengths traveled through the universe?(Riley)

They Travel, by depending on how long they can travel from each planet.

How would you describe the sun?(Riley)

A big ball of fire that is a star.it keeps us alive and very important to our survival

How many facts should we include about stars/galaxies?You decide how many and you think of that many facts about stars/galaxies.(Riley)

According to astronomers, our Milky Way is an average-sized barred spiral galaxy measuring up to 120,000 light-years across. Our Sun is located about 27,000 light-years from the galactic core in the Orion arm. Astronomers estimate that the Milky Way contains up to 400 billion stars of various sizes and brightness.

What examples can you find to create a planet?(Riley)

Formed from the same spinning disc of dust that formed the sun.This disc,called the Solar Nebula,was composed mainly of hydrogen and helium,but also had other elements in smaller proportions.
