The new subject is-

Can you guess?

Well you will have to wait until I do it.

The Last Post Is On Comets.

There are so many amazing things in our universe we cannot even begin to find all the things there are out there.
Comets are balls of frozen water, dry ice and rocks. As they move, they leave behind a trail of dust and dirt.
Once a year, the Earth passes through a Comet's path. When the dust and stuff hits the Earth's atmosphere, the dust and dirt catch fire. We call this a meteor shower. The best time to see it is between August 9th to August 13th.
The word 'Comet' comes from the Greek word kometes which means head of hair. And actually the Comets do look like they have hair.
The hair is actually all the steam rising off the Comets as they go on their orbit around the sun.
A Comet's orbit can be 200 years! Of course, some Comets like Halley's Comet only take 76 years to go around the sun.

Well I hoped you liked Astronomy as much as I did!

All The Stars In Sky!!!

There are billions and trillions of stars in the sky and GOD said HE will call each one by name. So there must be a great deal of names!
Our sun is just a star we just named it ours. But there are others as big as our sun if not bigger. I can't remember all there names but there were like three that where really big! We watched a movie once which had the stars in it. They showed earth compared to the sun and earth was tiny then the sun to another star and the sun was just a speck and they kept doing this and the one before would be just a speck!
When Christopher Columbus sailed to America he flowed the stars. All the explorers flowed the stars.
When people talk about light year that's how many miles light can travel in a year which is- 5,900,000,000,000 miles in a year.
The best time to see the stars is on a clear day with no moon and you can see trillions of stars!!!!!!

The Black Holes!!

When a star runs out of fuel it collapses in to it's self. Sins the star is so hot when it does this it explodes!
After doing this most of the star gets shot in to space but a small amount of the core stays.
When this happens the small amount of core has a great deal of mass. (Which is the gravitational pull.) The mass pulls every thing around it in to it and it gets so very dark because no light can escape the gravity.
And so it's called the Black Hole.
Scientists see how Black Holes effected the surrounding things. For example gasses move very quickly when there is a Black Hole near.
The universe is getting bigger and bigger and so we are moving away from any Black Holes.

Pluto!!!

Pluto is the last planet in our solar system and it is rather confusing so just try to stay with me.
Pluto is the smallest planet and it's number 9. But that's only part true. Every 248 years Pluto and Neptune change places Pluto becomes number 8. The last time Pluto became the 9th planet that was in 1999.
Pluto swaps with Neptune for about 20 years then goes back.
Scientists haven't been able to study Pluto very well because of it being so far away but they think it's about 390 degrees below zero over there. Pluto rotates in the opposite direction of most of the other planets and is like Uranus is on it's side.
All the planets orbit around the sun in all at more or less the same height but Pluto orbits up and down.
Pluto was discovered 1930 and 48 years later Pluto's moon Caron was discovered.
Earth's moon is equal to about a 50th of Earth's size but Caron is about a 6th of the size of Pluto.
Most People think that Pluto should be a comet because of it's size and behavior. But some think it should be a planet.
In 2006 NASA sent out a spacecraft that is supposed to reach Pluto in 2015.
Pluto also has something called the Kuiper belt which will probably need it's own post.

Neptune!!!

• Neptune is the second to last planet.
• It is a bright blue and it two wobbles while orbiting.
• Like Jupiter and Saturn Neptune as storms raging on it all the time. Neptune has a spot. It's called the Great Dark Spot. Scientist think that the storms on Neptune are mad of diamond dust.
• Neptune is smaller than Uranus it's inner core is rock and surrounded by liquid.
• A year on Neptune is 164 earth years, and a day is 16 hours long.
• Neptune is also very cold! It is 370 degrees below zero.
• Neptune has 10 moons the biggest of which is Triton which is 400 degrees below zero and Triton is moving closer to Neptune every day.
• So only 1 more planet to go.
• Second to last.

Uranus!!!

• Uranus is the second to last planet in our solar system!!!
• Now most planets spin around the sun but Uranus rolls. Just imagine that Uranus has a North pole and a South pole. While Earth is spinning the poles are be up and down(More or less.). But Uranus's poles would be straight out on both sides while spinning so that means that Uranus is on it's side.
• Uranus has 11 rings. The rings are straight up and down which effects Uranus orbiting and make it all wobbly.
• Like Venus, Uranus spins the opposite way from all the other planets.
• And being away from the sun Uranus is -350 degrees.
• Like Saturn, Uranus's rings have dust, rocks and moons. Two of the moons are Cordelia and Ophelia. Two of the characters from one of Shakespeare's plays!
• Believe it or not Uranus was only discovered in 1781 by William Herschel and his sister Caroline.
• One year on Uranus is equal to 84 Earth years. And one day is 17 hours.

Wow!!!

Saturn!!!

• Everyone remembers Saturn by it's rings.
• There are thousand of rings made up of rocks, dust,and ice that orbit Saturn.
• The rocks range in size from pebbles to houses and all the rings are different colors.
• Also in the rings are moons just orbiting Saturn.
• Saturn's ring is 50 miles thick.
• Saturn is the second biggest planet because it is next in size to Jupiter.
• Saturn is tilted just like the earth, but compared to Saturn the earth is a marble and Saturn is a soccer ball.
• Like Jupiter, Saturn is made up of hydrogen and helium gas.
• Being further away from the sun, Saturn is 300 degrees F. below zero on the surface and 20,000 degrees F. in the core of Saturn.
• A Saturn year is 30 earth years. And an Saturn day is just about 10 hours.
• Saturn has 30 moons and the moon that is almost as big as Saturn is Titan.

So, I think we've got every thing on Saturn.

Did you realize how many threes Saturn has?

Wow we are going through this very fast.
