Billion Years Ago Carbon Dioxide
1,230 wordsOur understanding and our modern perception of our solar system, the Milky Way, has been drastically reshaped from the corresponding perception of only a few hundred years ago. Our Solar System, the Milky Way is probably about 4 - 5 billion years old. Only in the last 400 years or so have we realized that the earth is not the "center", and that in the Universe alone there is an immense 200 billion "Suns" in a galaxy like our own. Although the origin of the solar system is uncertain, most scienti...

Surface Of Mars Olympus Mons
1,529 wordsNamed after the Roman God of war, Mars has sparked and sustained curiosity than any other planet in our solar system. Astronomers and Geologist have studied the surface of Mars dating back to 1965 when Mariner 4 swept by the planet. Photographs of the planet showed a barren surface scarred by numerous craters. It wasnt until 1976 that scientist got their first glimpse of the Martian Landscape from its surface. As we take a closer look at Mars we may find many similarities as well as differences ...

" (Astronomy) Ganymede is the largest satellite in the solar system; with a diameter of 3, 268 mi (5, 262 km), it is larger than the planet Mercury. In 1979 Io was observed by Voyager I and II and was found to have several active volcanoes actually in eruption during the spacecraft flyby. Io is the innermost of the Galilean satellites. Io's size and density is very sim...

Carbon Dioxide Solar System
1,582 wordsHumans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earths neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earths neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and ca...

Degrees Celsius Solar System
456 wordsMercury is the closest planet to the sun. It's average distance from the sun is approximately fifty-eight million km and it's diameter is 4875 km, making it the second smallest planet in our solar system. It's volume and mass are about 1 / 18 that of the earth and it's average density is approximately equal to that of the earth. Mercury's magnetic field is one-hundred times weaker than that of Earth's. Mercury has the shortest revolution of all the planets in our solar system and revolves around...

Gas And Dust Carbon Dioxide
1,584 wordsAsteroids sling through space, celestial debris of diverse origins, leftovers from the formation of the solar system, broken offshoots of parental asteroids or comets that have lost their glow. But if an asteroid were to smash into Earth, the result would mean a global catastrophe and life on our Planet could come to an end. The explosion would approach that of a million megatons of TNT- sixteen hundred times greater than the most powerful nuclear weapon ever tested (Barnes-Svarney 234). Asteroi...

North And South Olympus Mons
1,343 wordsGeology of Mars by Luke Just Mars is the planet that is the closest geologically to our own. Still we know little about the planet. All the information that we have is from what we see. We can speculate about the geology of the planet but we will never know for sure what the planet is really made of until we physically go there. The information is all from NASA sites or NASA related sites. Mars red color leads us to believe that the planet has large amounts of iron. This red color is the only co...

Earths Rotation Solar Wind
1,404 wordsTHE MOON Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moons phases. The time between successive new moons is 29. 5 days (709 hours), slightly different from the Moons orbital pe...

Shield Volcanoes Volcanic Activity
435 wordsKilauea Hawaii consists of a string of islands, or an archipelago. Kilauea is located on one of these islands, the central Hawaii island. Kilauea is one of the world? s most active volcanic craters. Craters are formed either by the massive collapse of material during volcanic activity, by unusually violent explosions, or later by erosion during dormancy (Compton's). It is situated on the southeastern slope of the great volcanic mountain Mauna Loa. Its elevation is 1111 m (3646 ft. ) above sea le...
