Jupiter was the first  planet  built

  • Stars build a planet.
  • The sun was much brighter than it is now.
  • Wallaby planets are known as planetesimal.
  • Some wallaby planets were destroyed and others had huge chunks ripped off.
  • Some of the larger planets emerged.
  • A graveyard of broken worlds now orbit the sun.
  • Jupiter is bigger than all the planets combined together.
  • Neptune is the coldest planet out of all of them.
  • In a rocket ship it takes nine months to get to Mars.
  • The atmosphere is so thin on Mars that water would evaporate in seconds.
  • Earth is in the middle of Mars and Venus.
  • There are over three hundred billion stars in our galaxy.
  • We have more stars than every grain of sand on Earth.                                              

There are nine planets in our solar system, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.

Our planet Earth is the third planet from the Sun.      

There is this thing that lives in toxic water. These terrific things are only found in the deepest part of a cave. They live on rocks and look hairy and squishy.

Jupiter was the first planet built. When all the planets weren't built except Jupiter, Jupiter kept on sucking up all the material,that all the planets  get made out of. So when a  supernova exploded it stopped Jupiter sucking up the material.

Not all planets have water on them. The closer you are to the sun the less water there is. Like Mercury for example, there would be no water on Mercury because Mercury is the closest planet to the sun.

The Milky Way

The Milky Way is a disk about 120,000 light years across. The disk is far from flat through. Two of the galaxy's neighbours - the large and small Magellan Clouds - have been pulling on the dark matter in the Milky Way like in a game of galactic tug - of -war. The tugging sets up a sort of oscillating frequency that pulls on the hydrogen gas (of which the Milky Way has lots of ).

How the Milky Way got its Warp

The most prominent of the Milky Way's galaxies -a pair of galaxies called the Magellan Clouds - appears to be interacting with the Milky Way's ghosty dark matter to create a mysterious warp in the galantic disk that has puzzled astronomers for half a century.

The warp, seen most clearly in the thin disk of hydrogen gas permeating the galaxy, extends across the entire 200,000 -light year diameter  of the Milky Way, with the sun and Earth sitting somewhere near the crease. Leo Blitz, professor of astronomy at the University of California, Berkley, and his colleagues, Evan Levine and have charted this warp  and in detail for the first time.

They found that the atomic gas layer is vibrating like a drum, and that the vibration consists almost entirly of three notes or modes.

Astronomers perviously dismissed the Magellan Clouds - comprised of Large and Small Magellan Clouds - as a probable cause of the galantic warp because the galaxies' combined masses are only 2 percent that of the disk. This mass was thourght too small to influance a massive disk equivalent to about 200 billion suns during the clouds' 1.5 billion year orbit of the galaxy.

The model not only produces this warp in the Milky Way,but during the rotation  cycle of the Magellan Clouds around the galaxy. People have been trying to look at what creates this warp for a very long time. Their simulation is still not a perfect fit, but it has a lot of the character of actual data.
