My Journey Through Sky Science!

Let's Blast off in 3..2..1..

The Big Wheel Of Cheese In The Sky[The Moon]

The moon was made billions of years ago from a large object that hit the earth and a whole bunch of rocks came out and they orbited around the earth until one day they finally melted together and the cooled millions of years after and formed the moon. For another 500 million years rocks pelted at the moon which created the craters in the moon.

The moon has no atmosphere so we can still see the damage done millions of years ago.

If you look at the moon when it is almost full you can see the moon's seas. They are not actually seas they are big pools of lava. From earth we can only see one side of the moon because the other side is always turned away. Pictures taken from the other side of the moon shows the exact same kind of damage.

The Twinkling Stars

When you are camping, out of the city or in the desert you can see thousands of more stars then if you where in the city because there are no city lights to mistake as stars. The of stars temperature are measured across the bottom of the kelvin scale. The smaller the stars the less mass they have. The colour of the stars is determined by the temperature. Most of the stars in out solar system are main sequence stars. There are thousands of red dwarf stars. The red dwarf stars burn their fuel very slowly so they will last longer then the sun because the sun uses a lot of it's fuel everyday. When you look closely and on a clear night with no clouds you might be able to see part of out galaxy, the milky galaxy. The white dwarf stars are at their very end of their life, they are losing their brightness. 63.3 moons can fit into the sun. The sun is actually a star it is not a plant or anything else, it is a star. The sun isn't the biggest star though, the sun is only a medium sized star, and that means that there are stars out there that are so much bigger then the sun. The sun also takes up 99.9% of the mass in the solar system. Zero kelvin equals- 273 degrees Celsius- 459 degrees fahrenheit.

How Do I Look At The Sun Safely

It is really important to make sure when you are viewing the sun to look at it with something that will protect your eyes. Before you can look at the sun you have to filter out 99.9% of the suns light. Thats why it is important to look at the sun with something safe because in thirty seconds you could be blind. The colour in our skin called Melanin is what protects us from the sun. You can look at the sun with a number fourteen lens for a telescope and you can also build a sun pin hold camera.

Summer Solstice- June 21

  1. Marks the end of spring and the start of summer.
  2. We receive the maximum amount of sunlight in the northern hemisphere on this day.
  3. The sun is high in the sky.
  4. The suns ray's hit the earth more directly
  5. The direct rays of sun cause the ground to warm more effectively.
  6. Solar noon on the summer solstice is the highest the sun ever seems to get in the sky

Winter Solstice- December 21

  1. In the winter the sun is always low in the sky.
  2. The suns ray's are spread over a larger area of the ground.
  3. Each patch of the earth does not receive as much of the suns energy.
  4. Solar noon on the winter solstice is the Lowest the sun will be in the sky.

Equinox- Equal Days And Nights

Spring equinox- When it is the spring equinox, the southern hemisphere has their automm equinox and vice versa.

Fall/ automm equinox

The Moon Phases

  1. The first phase of the moon is the new moon, this when there is no moon showing, there is just they sky. There is actually moon in the sky but the light from the sun just isn't reflecting off of the earth to the moon so it can reflect back onto the earth.
  2. The second phase of the moon is the waxing crescent. The light is only hitting a little sliver of the moon.
  3. The next phase is the first quarter is actually the first half but you can really only see quarter of it so it is the first quarter. It is half way from being a full moon.
  4. Then you have a waxing gibbous where almost all of the moon is showing but sun earth moon and sun just have to rotate a little bit more.
  5. Full moon! All of the moon is showing now and the moon is nice and bright.
  6. Now we have to go back to the new moon so the next phase is the waning gibbous. The other side of there only side we can see from the moon has light now.
  7. Now there is the last quarter. We are almost at the new moon but there is still half of the moon in the light.
  8. The next phase before the moon is a waning crescent. Only a little bit of the moon is showing now.
  9. New moon once again the moon has no light reflecting it. This cycle takes about 28 days.

Why Is Venus Called Earths Twin?

Scientists call venus earths twin, you may be asking why is that?.Well I am here to tell you why. Venus and earth are the same size. That is pretty much the only reason they call it earths twin because on the other hand venus has poisonous atmosphere. That means that no one can live on it because it is super hot and there is almost no oxygen there to breathe.

The Solar System

  1. The fist planets witch are called the inner planets are: Mercury, Venus, Earth and mars. They are called terrestrial planets because they have a hard rocky surface.
  2. The four outer planets witch are called the gassy giants are: jupiter, Saturn, uranus and neptune.
  3. In between the gas giants and the inner planets there is the asteroid belt.

The Universe

There are billions of galaxies in the universe. Some are very small with only a few million stars. Some have more like 400 million stars. Three kinds of galaxies- spiral galaxies- elliptical galaxies- and irregular. The only difference between them 9is the shape of them. The black hole has two different parts- the inner event horizon and the outer event horizon. The most beautiful type of galaxies are spiral. Their long twisting arms are where the stars are formed. Like ripples in a pond, the spiral arms seen in this kind of galaxies are cycling waves.
