Prologue to Astronomy Mr. Lewis Music, Motion, & Multimedia, 2007

observatory : a place or building that utilizations extensive telescopes for watching space.

planetarium : a domed room in which demonstrates the night sky from any areas whenever far in the past to far later on. Some planetariums can demonstrate all vault movies encompassing the group of onlookers with the activity.

Galaxy cosmic system : a substantial bunch of stars (several millions to trillions of stars) gravitationally bound together. NGC 5866 is tilted about edge-on to Earth's viewable pathway . Andromeda Galaxy, M31

Nebula cloud : a huge billow of gas and tidy. Falcon Nebula

Asteroid space rock : stone to mountain-sized bit of shake staying from the early nearby planetary group. The biggest space rock is just 1000 kilometers crosswise over yet most are much littler. Space rock 951 Gaspra

Milky Way Galaxy Milky Way Galaxy : the expansive winding world in which our Sun and planets live. Our Sun is one star of a few hundred billion in the Milky Way.

Sun : the star at the focal point of our nearby planetary group.

Mercury : the nearest planet to the Sun.

Venus : the second planet from the Sun. "[Venus's] air is made for the most part out of carbon dioxide. There are a few layers of mists numerous kilometers thick made out of sulfuric corrosive." It's weight is 90 times that of earth. A few regions of the planet are hot to the point that they would make lead liquefy. Source: www.nineplanets.org .

Earth : the third planet from the Sun.

Rotate turn : when a question turns

Revolve spin : when a protest moves in a round like example (circles) another question.

Orbit circle : the way one question takes around another protest.

Our Moon : a rough circle that circles the Earth. "Most shakes on the surface of the Moon appear to be somewhere around 4.6 and 3 billion years of age." Source: www.nineplanets.org .

Craters pits : an opening in the ground had by the effect of a shooting star. Meteor Crater in Arizona, 49,000 years of age. Aristarchus and Herodotus on the moon

Greenhouse Effect nursery impact : the catching of warmth vitality near a planet's surface by specific sorts of gasses in the air (e.g., water, methane, and carbon dioxide). These gasses permit noticeable light from the Sun to achieve the surface however keep the infrared light from the warmed surface to emanate back to space.

Mars: fourth planet from the sun. Mars once had fluid water on it and along these lines, perhaps life. It might even now have fluid water and life on it underneath the surface.

Valles Marineris Valles Marineris : an enormous ravine. It is found on Mars.

Olympus Mons Olympus Mons : the biggest mountain in the close planetary system. This mountain is a spring of gushing lava and found on Mars. Practically as large as the condition of Arizona

Jupiter Jupite r: the fifth planet from the Sun.

Europa One of Jupiter's moons, Europa may have a profound sea of fluid water on it and thusly may have life in the sea. "Jupiter has an aggregate of sixty-three moons, going from minor "moonlets" just a couple of miles in distance across up to mammoth Ganymede, which is bigger than two of the planets in the close planetary system. The four biggest moons are known as the Galilean moons since they were found by Galileo Galilei when he began utilizing his primitive telescope right around five hundred years prior."

Great Red Spot Great Red Spot : a monster sea tempest like tempest that is around 2 times greater than the span of Earth.

Saturn : the 6th planet from the Sun.

Uranus : the seventh planet from the Sun.

Neptune : the eighth planet from the Sun.

Pluto : Pluto was authoritatively renamed from an undeniable planet to a "dwarf planet" on August 24, 2006. That implies Pluto is no longer considered a genuine planet. Therefore, our nearby planetary group now has just eight planets. Charon

Questions to Ponder How is it conceivable that Earth and different planets don't collide with each other? Why does the moon show up so cratered and Earth does not? Is it feasible for a space rock to hit Earth? What causes the seasons on Earth? How does the sun make vitality? Is there life on different planets?

Questions to Ponder Are people in charge of the nursery impact? Ought to Pluto be renamed as a "genuine planet?" What causes gravity? How quick is our nearby planetary group going through space? Is it conceivable to make a circumstance on the moon that permits life to exist?

Questions to Ponder Are the risks required in space travel really justified regardless of the learning that people accumulate when they go in space? How is it feasible for a gas planet to remain a "gas planet?" Gas has a tendency to go it's on route on Earth. Since light voyages, does that imply that if a star detonates and it is 2 million light years from Earth, did the star really detonate 2 million years prior?
