Its magnetic field indicates large amounts of molten nickel and iron in outer core. The moon lacks a hydrosphere/atmosphere/magnetosphere. Tides occur cause a tidal bulge which is the difference in the moon and earths gravitational force. Spring tides=high tide, neaptide=low tides. Highest and lowest tides occur during new and full moons.
Speed relative to CMB rest frame is 552 km/s. The Milky Way is the second largest galaxy in the local group.Andromeda Galaxy is bigger than the Milky Way. Mass of the Andromeda Galaxy is 7×1011 solar masses (Mo). The Milky Way's steller disk approximately 100,000 light years in diameter and 1000 light years thick. Mass of the Milky Way is 5.8×1011 solar masses (Mo).
In cosmogony, the nebular hypothesis is the most widely accepted model explaining the formation and evolution of the Solar System. There is evidence that it was first proposed in 1734 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular hypothesis is Solar Nebular Disk Model (SNDM) or simply Solar Nebular Model. According to the nebular hypothesis, stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds (GMC).

The four giant gas planets that are made primarily of lightweight elements are A. Mercury, Venus, Earth, and Neptune. B. Venus, Saturn, Uranus, and Neptune.
2/ The moon rises and sets later than the last time I observed. I noticed that the moon rises and sets approximately 50 minutes later than the night before. Here are some changes that I noticed: Moon phase | East (Rise) | Southeast | South | Southwest | West (set) | Waxing Gibbous | Afternoon | Dusk | Evening | Midnight | Pre-dawn | Full moon | Dusk | Evening | Midnight | Pre-dawn | Dawn | 3/ The sequence of moon shapes that I observed were Waxing Crescent (observation 1 – 3) to Waxing Gibbous (observation 4 – 8) that stretched out till it reached full moon. During Waning Gibbous and New Moon, the moon is below the horizon, I couldn’t observe the changes of the moon. Between the phases – waxing crescent, waxing gibbous, and full moon– I noticed that the waxing gibbous (observation 4 – 8) and (observation 11 – 15) took a few days to evolve and move on in the cycle.
Target Earth: Asteroid and Comet Impacts by Philip Plait discusses issues involving what effects meteors, meteoroids, meteorites, asteroids, and comets have on Earth. Earth gets hit by twenty to forty tons of meteors every day. Most of it is detritus, a material made up of small rocks that burn up in the atmosphere. Detritus is what we see when we see a "shooting star". The big question is; how is something so small, so bright?
Jacob Egan Atmospheres of the Outer Planets Comparison of Jupiter and Saturn The planets of our solar system are diverse in nearly all aspects. These include composition, distance to the sun, temperature, rotational speed, revolution speed, and even axises of rotation. The atmospheres of our planets are but a small part of the diversity of the planets, but an intriguing one to say the least. In these pages, I hope to compare two of our outer planets – Jupiter and Saturn – in relation to their atmospheres. Unlike Sol's inner or Terrestrial planets, which are relatively rocky with thin atmospheres – the outer planets or Jovian planets are the opposite.
Quasars are a group of galaxies that are near the closest and brightest object that ranges from 2000 million LY to 10,000 million LY from earth. Black holes and quasars are formed out of different things in space. Black holes are formed from when stars or other objects collapse or explode from their own gravity source. Nobody is really sure how quasars are formed but some believe in theories regarding their creation. Black Holes and Quasars are both detected by x-rays.
The second proof is the declaration of Dr. Norman about these special rocks. He said that they had discovered pieces of glass in the moon rock that were the result of meteorite impacts and volcanic activity over billions of years ago. Also he added that this kind of volcanic glass does not belong to the Earth because it can be destroyed immediately by water in the world in few million years; due to this explanation it is almost sure that the rocks came from the Moon. Finally, the third fact is given by Dr. David McKay, Chief Scientist for Planetary Science and Exploration at NASA’s Johnson Space Center (JSC). He has hundreds of documents about the origin of the Moon’s rocks brought by Apollo.
The moon landing is also of such astronomical precision, based on the Orion Star cluster. Either the sea of tranquility is a constant match as the great Pyramids of Egypt on planet Earth. The time chosen to land on moon is also set according to the astronomical constant happen with moon and Orion Cluster. The landing and takeoff from moon happened within the same time, when those astronomical constants were happening in the moon for few
