Using the regular webslides we have used thus far:

Here are also some help links if you need them:
http://en.wikipedia.org/wiki/Asteroid_belt
http://en.wikipedia.org/wiki/Kuiper_belt
1. Describe our solar system being sure to use the following terms correctly:
* solar nebula theory of solar system development
* terrestrial planets
* jovian planets
* THE asteroid belt
* kuiper belt
* frost line - an imaginary line that demarcates one area from another [I'm being vague on purpose so that I don't explain it]
2. Explain the process of accretion.
3. The objects in the solar system can be classified as: terrestrial planets, jovian planets, asteroids or comets. From the readings, explain why the inner planets are terrestrial and the outer planets are gas giants.
4. Similarly, what caused the asteroid belt to form where it is?
5. The first web page in the web slide suggests some predictions a good solar hypothesis should account for. These include the fact that most of the planets revolve around the sun in the same direction, the terrestrial planets are near the sun and the Jovian [gas giants] are farther from the sun and the location of the asteroid belt and source of comets. Explain how does the solar nebular hypothesis account for these important facts of our solar system?
6. Compare and contrast the characteristics of the four terrestrial planets. Compare and contrast the components of the atmosphere, max and min temperature changes, orbital period [length of year], orbital eccentricity, rotational period [length of day] angle of tilt and distance from the sun.

Our Solar System
Solar nebula: “the disc-shaped cloud of gas and dust left over from the Sun’s formation.” (Wikipedia)
Our solar system was created by something called the solar nebula hypothesis. The theory tells us that our solar system was created from a small collapse of a molecular cloud. As more mass collected to a certain point as it collapsed it created our Sun in the centre. This caused the rest to flatten out to form a… Continue

Origin of the Universe
There are two theories that explain the existence of the universe; the Big Bang Theory and the Steady State Theory.
The Big Bang Theory suggests that about 12-15 billion years ago all matter and energy exploded and expanded from an original point of nothing. This was when both time and space were created.
The Steady State Theory states that the universe is expanding and has no beginning and no end. It exists without changing… Continue

• Solar nebula theory
- Solar nebula theory is about how stars and planets form. Basically, this theory explained about how our solar system formed. This describes the slow collapse of a nebular cloud into a protostar. While a star is forming in the centre of the collapsing cloud, the outer, cooler regions of the cloud swirl around the central protostar in a disk-like structure called solar nebula.…

Falcon 9 aborts launch attempt
A SpaceX Falcon 9 aborted its launch May 19 moments after its engines ignited when computers detected higher pressure readings than allowed. The center engine pressure built above limits and a shutdown occurred one-half second before liftoff, SpaceX officials said.Newfound exoplanet may turn to dust: Planet’s dust cloud may explain strange patterns of light from its star
Researchers have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris -- much like the tail of a comet -- is following the planet, and that this tail may tell the story of the planet's disintegration. According to the team's calculations, the tiny exoplanet, not much larger than Mercury, will completely disintegrate within 100 million years.What astronauts ate: Apollo 10 space meal, 1969
This Smithsonian Snapshot marks the May 18, 1969, launch of the Apollo 10 mission with an astronaut's space meal from that mission.Days of 'gizmo' launches return: NASA team to test new vehicle-descent technologies
NASA technologists will get a chance next summer to relive the good old days when Agency engineers would affix space-age gizmos to rockets just to see if the contraptions worked. In what will be the first of four high-altitude balloon flights to begin in the summer of 2013, technologists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and Wallops Flight Facility in Wallops Island, Va., are preparing to test new deceleration devices that could replace current descent technologies for landing ever-larger payloads at higher elevations on Mars.Meals, Equipment Top Cargo List for SpaceX spacecraft Dragon
