What's up with the Sun and the Moon?


So, we've learned a bit about eclipses and moon phases in class...but we all had tons of questions about our pals, the Sun and the Moon. Here's what we wondered about and what we found out!

Why is the moon red during a lunar eclipse?

The Earth's shadow is very long and it starts from the ground. It is about 200,000 miles above earth, so it goes very close to the moon. The veiw from the moon would be Earth's nightside, the dark half of our planet is opposite to the sun. But its not COMPLETELY dark. All around the Earth's limb, the atmosphere glows red. Thats why the moon looks red to us during a lunar eclipse.

Why is a moon considered a moon and not just a rock in space???

There is actually no real definition of the moon. There are some rocks in space that are so small, yet they fit what a moon could be. If this were true, there could be thousands of moons in the solar system! You could also say there are millions if you count the debris on Saturn's ring! Some people say that there should be a seperate catagorie for "minor moons." So there is no real answer to this question.

How Does the Sun reach the Inner Planets and get Them so Hot?

During my research I found out that the Sun reaches the inner planets because the outer layer of the sun is hot and stormy. They have gases that shoot out and form a solar eruption. With all of tese solar eruptions continuously happening it forms a solar wind and it covers the whole solar system. The website that I used was called: http://www.nasa.gov/worldbook/solarsystem_worldbook_update_prt.htm this was a very useful website because it explained how the eruptions and winds happened. In conclusion I still have one question which is why are the outer planets so cold if the sun can reach them? To me I think that this happens because the planets are made up of mostly gases.

Why is the light from a solar eclipse so blinding?
The light from a solar eclipse is very blinding and can damage the eye. Special protection is needed to watch a solar eclipse. In Togo, they made special protective glasses to watch this amazing event. Togo’s minister of health said that the corona is the lightest part and the most dangerous that can blind you. The corona is the Sun’s atmosphere. The corona is visible only when the moon blocks out only the main disk of the sun. The glasses are paper-rimmed and have dark plastic lenses that look like glasses used to watch 3-D movies. I got all of this information from http://www.space.com/scienceastronomy/060328_eclipse_overview.html.

My question was 'How come the sun is so hot and how'd it get hot?' I found most of my answer on http://www.space.com/scienceastronomy/070418_solar_music.html this is what I found: It has been recorded that the sun's atmosphere can sing! We can not hear it but 'explosive events at the suns surface trigger acoustic waves that bounce back and forth between both ends of the magnetic field loops' this may help explain why the sun's corona so hot. The sun's surface is 10,000 degrees farenheit. this is al that is known.

My question was "why is the sun so bright in a solar eclipse." I found out that the sunlight around the moon (sun's corona) is what mostly blinds people. The suns raise is so bright and really big that the light goes on the outside of the moon. Just looking at a solar eclipse for 1 sec will blind you.

My question was "Why does the moon turn a rusty orange color during a Lunar Elcipse?"
I found out that it turns a rusty orange color because earth's atmoshpere causes sublight to change directions and partly shines on the moon causing it to become a rusty orange color. It changes if there is an unusually large amount of dust after a volcanic eruption.
A new question that I have is "Why does the Earth's atmosphere change the direction of the sunlight?"

why does the sun stop its nucleas fusion? because when the sun joins the hydregen addoms and they fuse creating heat and light
eventuly it will run out of hydredgen and burn out. http://www.space.com/searchforlife/seti_turnbull_040429.html

How was the sun formed?

The sun is about 4.6 billion years old. It was formed over a long period of time. Most scientists believe that the sun started as a tremendously big star in a cloud of gas and dust. Ultraviolent radation made a bubble of boiling gas move out through deep space. A shock wave then forced this bubble of boiling gas to start to be pushed in or compressed. This then caused a reaction to make the sun and other stars form. In the next 100,000 years the cloud around the sun was destroyed by another gas bubble. Since this cloud was now gone the sun was exposed to every single planet in our solar system. The sun then evaporated everything from every planet.

I learned that the sun had three very bad flares, not even in one day,the way the sun has fire on it is because its atmosphere which apears to be a ruby so called the ring of fire the atmospere is also called the corona which means that if you were next to it and started to move away form it you would get warmer instead of getting cooler. no scientists have figured out why this happens but they are still trying to. I got this info from http://www.nasa.gov/vision/universe/solarsystem/ring_of_fire_media.html

How did the Sun become so HOT?

The Sun formed in a very interesting way and this is how. Our Sun and the Solar System together formed a slowly rotating molecular cloud made of different gases and dust. This newly formed cloud began to compress under its own gravity. As it compressed it began to spin faster & faster. This spinning flattened the cloud into a disk. The center of the disk formed a gas sphere. The sphere attracted material from the disk and while attracting the materials the sphere compressed which made the temperatures and pressures increase a lot every time it was compressed. At this point the Sun(a star)was formed. With the remainder of the disk our planets formed.

Do solar eclipses happen in patterns?

Eclipses do come in patterns. The earth averages 5 solar eclipses per year. The first people to study eclipse patterns were the natives in england about 5000 b.c. who built stone henge. Stone henge was used to tell when a solar eclipse came if it was a total eclipse or not. The people who made stone henge ended up finding out about almost everything about the moon. Solar Eclipses happen every 5 years and a total solar eclipse can never be seen from the north or south pole. So those are the only places on earth that don't average 5 solar eclipses a year. Solar Eclipses happen many 5 times a year, but they may occur those 5 times in the same exact place only. The eclipse pattern usually comes, in an eclipse every 2-3 months. Other wise they have come a bunch at the beginning of the year and 1 or 2 at the end. Otherwise it is 1 or 2 at the beginning and a bunch t the end.

Why does the earth only have one moon and other planets have more?

Why is it that there are only 8 planets in the solar system and there are 150 moons? Well you're about to find out. Lots of scientists have theories. There are two major theories. The first major theorie is that something big impacted the planet and broke off a portion of it. The second theory is that some of the moons are astroids that got captured by the planets gravitaional pull, so during that earth could have only captured one asteroid. That is why the earth only has one moon and others have more.

how does the sun keep burning?

the sun keeps burning because it burns hydrogen at its core. as the sun burns it uses up its hydrogen. when it stops using hydrogen it turns into a red giant. the red giant starts to use helium and loses a lot of its mass because of stelar winds (stellar winds are when ionized gas comes out of a star). the materials that come out of the sun are thought to have a lot of helium3. when a star is completly destroyed it explodes in a colorful array of colors.

Question: Why is the sun white during a solar ecplise?

Answer: The suns white during a solar eclipse becuase the moon blocks out alot of the suns bright light so the fainter corona is visible. This is the only time the corona is visible from Earth and this is the only time you can see the white of the corona. Most of the sun is usually hidden from you since it is so bright. After a solar ecplise more of the stars appear in the sky and the sky is filled with many colors. Solar ecplises are not often, in the past 25 years there have been less than 16 solar eclipses. By the time you would wait for this event to come to your home town,(a solar eclipse), you would be waiting about 400 years. The moon blocks out the light and shows you the rare occurance of the suns dimmer corona. http://www.space.com/spacewatch/060324_night_sky.html

My question was why can we only see the corona of the sun in a solor eclipse and i also asked what is a corona.

Well after doing a lot of research in class i discovered that a corona is like a pearly white crown of light around the sun.
A corona can also be described as a low-density, hot gas that glows with a palo white color.

Also after a long period of researching i have discovered why we can only see the corona of the sun during a solor eclipse. I found out that you can only see the suns corona during a total solor eclipse because the wave that comes out of it, we cant see with the human eye. I also found another interesting fact about the suns corona is that the suns corona it is the outer most part of atmospher.

Why does the moon not have a specific name?
http://www.newton.dep.anl.gov/askasci/ast99/ast99509.htm

When you research other planets, you see that they have specific names. It is the same with our moon but for us the real and specific name is the Moon. When you research other planets moons come up as moons, without a capital M. That is how you can tell. It is not very creative but it is the name.

Why is the umbra so small?

Usually during a luner or solar eclipse there is a small spot that you can see the eclipse in. That is called the umbra. The umbra is a small dark circle. It is much darker than the penumbra and it is smaller. The umbra is small beacuse the earth is blocking a part of the moon in a Luner eclipse and the moon is blocking a part of the earth in a solar eclipse.

Why does the moon turn orange during a lunar eclipse?

The reason why sunlight reaches the moon even though the moon is in the earths umbra during a Lunar eclipse, is because when the light passes through Earth's atmosphere the light bends. Dust particles in Earth's atmosphere removes some of the bluer colors in the sunlight so only the redder colors make it to the Moon. The amount of dust determines the darker color of the red.

Unknown said...

How many solar eclipses happen in a year?

A solar eclipse happen about two times per year somwhere on earth.
The maxium number of solar eclipse
is five per year. A total solar eclipse only happens about once every 1.5 years. Also a total solar escipse is not noticeable until the Sun is more than 90 percent covered by the moon. The longest time for a total solar eclipse is 7.5 minutes.

What are sunspots?
Sunspots are planet-sized whirlpools of intense energy. They are dark and they hold itself together in the face of energy. Sunspots are on the surface of the sun. They are dark, cool, powerful magnetized, and fleeting. Sunspots are cooler, dark regions of the Sun that sometimes grow to be the size of Earth and then they fade away. Sunspots have twisted feilds of magnetic energy. They usually last a few days to a few weeks and then they disappear.

How did the sun become as big as it is today?
Did you know that the sun is just a star? Well it is and if you think that the sun is big, then just think that the actual cutoff for a star is 150 times the size of the sun. The reason the sun is as big as it is today is because it was just born that way. The sun is actually a medium sized star. It just appears big because it is closer to earth than some of the other stars we can see. So the sun is just a medium sized star, who figured?

Why does the moon turn into a reddish color during a lunar eclipse?

The moon turns a reddish color during a lunar eclipse because the earth casts a shadow on it. The shadow is almost a million miles into space, far enough to reach the moon. The dark half of the planet is facing away from the sun. This means that the dark half of the planet is pointed towards the moon, but it isn't completely dark. What it is is that it is sunrise and sunset everywhere on earth all at once. That is why the moon turns a reddish color during a lunar eclipse.

Are there different eclipse types?

I found out that there ar different kinds of eclipses besides lunar and solar. There are only different ones for lunar though. there is a Penumbral lunar eclipse, which is when the Moon passes through Earths penumbral shadow, and it is very hard to see. There is a Partial Lunar eclipse, this is when a part of the moon passes through Earths umbral shadow, and is very easy to see. The las one is a toal lunar eclipse which is when the entire moon passes trough Earths umbral shadow, this can cause a large vibrant range of colors.

How hot is the sun and will it ever burn out and if so when?


The Sun's core temperature is about 27,000,000 degrees F. But the part of the sun that we see is about 5,500 degrees C which is about 10,000 degrees F. It is said that if the sun burns out that it won't burn out until about 6 billion years.

What is a corona ?

A corona is the outermost region of the sun's atmosphere, which extends into millions of kilometers into space. It is the most easily seen during a total solar eclipse, but also can be observed in a coronagraph. The corona is much hotter than SUn's surface. The corona is also known as the aureola, which scientists use. The Sun's corona is only visible during a solor eclipse, which appears to look like a white halo. The Sun's corona is made of ionized gas between approximately 1,000,000°K and 2,000,000°K and has an extremely low density.

Why does the moon turn red durring a lunar eclipse?

The moon turns red durring a solar eclipse because if you look at earth from the moon's point of view you would see the sunlight of dawn and sundown surounding the earth. That light floods into the shadow and casts a red shadow on the moon. the dark side of the earth looks red too.

What is A Solar Flare?

A Solar Flare is a violent explosion in the sun's atmosphere. A solar flare can cause an enegry equivalent to a billion megatons, travleing normally at about 1 million km per hour that is the same speed as the speed of light.The flares can affect the electromagnetic transmissions of many earthbound communication devices including Computers, and cell phones. Most solar flares take place in the corona. Most solar flares occur next to a sunspot.

HOw was the sun formed?

The sun was formed4.7 billion years ago. It was formed over a very long period of time. Most people belived that the sun started as a tremedyouly in a big star in clouds and dust.From start to finish, it took something like 10 million years to form the sun and planets from a collapsing cloud of gas, and this is not very long at all!!The cloud collapsed for millions of years until it formed a rotating disk with a large central bulge. Out of the disk would eventually form the planets, and out of this central bulge where most of the mass wound up, formed the sun. We see such rotating disks of gas around many infant stars embedded in nebulae so this has confirmed this basic picture during the last 15 years or so. This isn't just 'theory' anymore.

why does earth have only one moon and other planets have more then one?

one reason we only have one moon is because earth is to small to have more than one moon. since saturn and jupiter have many moons is because these planets are much bigger than earth and because they don't have a gravity problem. there also was a theory saying that moons are caught to be asteroids. earth have a big gravity problem so it would make it easier for them to catch small planets and asteroids. the other theory was that the moon was formed right after than earth was.

Unknown said...

why does the earth only have one moon?

We dont even know why the earth only has one moon. If the conditions were a little differnt we would have 2,3, or none at all. we think most of the time the bigger the planetthe more moon.One theory i find was the reason we have one moon is because a piece of the earth feal off and it mad a moon do you believe that.

How are sunspots Made???

sunspots are colder parts of the sun that look black. They are made by the changes in the suns magnetic field. Then tubes and tunnels form inside and rise to the surface creating a dome-like bulge. As a result of this, the heat cannot heat this spot as much as the regular space of the sun. the heat of the sunspot can be 2,000 degrees less than the reg. spage on the sun.

How big is the sun? How hot can the sun get? What is the hottest part of the sun?

The sun's diameter is 1,390,000 km long. The sun is about 3 million miles around it's equator. The mean surface temperature of the sun is 9944 degrees Fahrenheit. The hottest part of the Sun is in the center. The center of the Sun is the core. The tempurature in the core reach 18 million degrees Fahrenheit.

Why are there so many craters on the moon?
All the moons and planets in our solar system have craters,but not all of them are visible. All of these craters are from meteroites that hit the moon or other planets. The moon appears to have alot more craters than the earth but actually have about the same ammount. The only reason the earth appears to have no craters is beacuse there is weathere to wear them away. But on the moon there is no weather to wear away the craters.

What is the sun's corona?

The reason why I decided todo this question was because i did not know a lot of about the sun's corona. Here is some information about the sun's corona. The sun's corona appears when there is a total solar eclipse. Then for a few minutes after the moon completely covers the sun a glow would appear. Here are some interesting facts about the sun's corona. The temperature of the source of the corona heat remains unknow. My last interesting fact is that the sun is made out plasma.

my question was: why does earth only have one moon when other planets have multiple moons.

The outer planets, Jupiter, saturn, uranus, and neptune have 90 moons combined. The inner planets only have 3, earth's moon and two small moons around mars. When the solar system first started out, it waas just a big, swirling cloud of gas. The highest amount of gas was in the center forming the sun. Farther from the sun, their was some rock, witch began to form planets. Their was left over rock and dust from the planets and the sun, and these formed together and created moons. The reason some planets have more moons then others is that there was more gas and dust in those areas to form moons, giving Jupiter and Sturn many moons. The reason the inner planets don't have many moons is because the sun took up most of the gas and dust, and much of what was left was put into the inner planets.

My quesiotn is: How big are Sun spots and why are they black?

Some are as large 50,000 miles in dimater! As they move they might get bigger! Some are planet-sized! The reason why there are dark is because: They are cooler than, many areas around them. Some tempertatures are: about 4,000 K (about 3,700 C or 6,700 F).

Mr. Saito said...

Ever since I saw the aurora borealis lights dancing in the night sky of Alaska, I've wanted to know more about them. In case you didn't know they are related to the sun because solar wind carries charged particles and when they are absorbed by substances in the earth's atmosphere they give off a glowing effect.

How do the different colors form? Most of the lights are green due to atomic oxygen. At higher altitudes, the oxygen can appear red. Atomic nitrogen can show up as blue and purple.

Are there auroras on other planets? Jupiter and Saturn have tons of auroras because their magnetic fields are much stronger than Earth's magnetic fields.

Can we see auroras in NJ? Yes, I found some cool pictures on the internet taken from NJ and NY.

Unknown said...

How is the sun able to produce so much energy and light for such a long period of time?

the reason how the sun is able to produce light is that it hydrogen inside of its core. energy is created because protons are turned into helium nuclei into energy. the energy is turned into matter energy. and then it is sent out into space 4.26million tons per sec. the sun can last so long because of its size. because the sun doesn't have the right size to explode into a supernova, it has different stages. then in one of the stages it turns into a red giant which is much larger than the sun in our present day. the last stage is thw black dwarf. in the black dwarf the sun no longers produce energy or light.

How often do lunar and solar eclipses occur?

Solar and lunar eclipses happen pretty randomly. The only pattern that stays the same is a lunar eclipse always occurs during a full moon, and a solar eclipse happens during a new moon. Usually though lunar eclipse happen much more often then solar eclipse. The next solar eclipse is on September 11, 2007. It will start at 10:25:46, and end at 14:36:33 UTC time. It will also be a partial eclipse, and will be seen in Antarctica, S. America, and S. Atlantic. The next lunar eclipse will be on August 8, 2007. There are no times posted, but it will be visible from Asia, Oceania, and the Americas, and it will be a total eclipse.

CaitieBee said...

my question was why does the moon turn a rusty orange during a total lunar eclipses. i found out that it is that color because the atmosphere bends sunlight to the earth's shadow. the color is the results of the refraction. this same procedure happens during the sunset. it's an amazing sight to see when it's ouyt espeisially since it only comes out once in awhile.

Why do the moon and oceans work together to create tides?

The moon and ocean work together because of the moon's gravitational pull. The sun also has a gravitational pull, but it is weaker then the moon's (on oceans at least).
When moon and sun are aligned, their respective tide bulges add together to a spring tide every two weeks. When sun and moon are at right angles it causes the bulge of the sun to add to the low tide, resulting in an overall higher low tide but lower high tide. This is called the neap tide.
