The Moon controls tides, which is 71% of the Earth 's surface. The origin of this object has been a question for many years. The most believed theory for how the Moon formed is called the Giant Impact Theory. This theory shows that a mars sized object came into Earth 's orbit, resulting in a collision. This collision caused a piece of Earth and debris to break off.
This finding of the impact crater is very important because that implies the rocks at the rim of crater provide give scientists more information about the origin of the moon, the moon in the ancient time. Comparing the number of impact craters on the Earth to the Moon and other terrestrial worlds, we could say that it is very rare. There are many reasons that could explain why other planets will be more impact craters than the Earth, for example, Earth’s atmosphere, geological activity, and human activities could be responsible to the phenomenon of lost impact craters on the Earth. First, the Earth’s atmosphere, a lot of smaller meteorite or comet cannot get through Earth’s atmosphere. They burn up after entering the Earth’s atmosphere, thus a lot of them did not make
June 30th, 1908 marks the date of a vicious asteroid impacting near the Tunguska River in Siberia. This event, known as the Tunguska Event, came into Earth’s atmosphere traveling at an extremely high speed and at a height of about 8500 meters the asteroid blew up due to the high temperature and pressure and it is said to have released so much energy that it would be equivalent to 185 Hiroshima nuclear bombs going off (Phillips). Over 800 square miles of forest was destroyed in the blast and there are even accounts of people being blown away by the shockwaves and feeling immense heat while being over 40 miles from the place of explosion (Phillips). Tunguska was a display of how powerful and dangerous a NEO can be to Earth and another large NEO impact was more recent on February 15, 2013. Although not as large as the Tunguska Event, the Chelyabinsk meteor still released more energy than a nuclear explosion and it was actually more fatal than the former as over 1,200 people were injured by the shockwave coming from the asteroid as it broke apart over the Russian city of Chelyabinsk (Howell).
The different gravitational pulls of the four types of stars show the different effects on space-time. The first star is our star in th center of the solar system referred to as the sun. The last star is a neutron star. Neutron stars are extremely dense star with a gravitational pull of two hundred billion times that of Earth. If a person lived on the sun in the center of our solar systems, and then traveled to a neutron star and lived there for one year, when the person went back to the sun he left, hundreds of years would have passed.
From the plans of the 2020 mission to Mars by NASA to the successful test launch of the first ever reusable rockets by SpaceX, we are closer than ever to being able to affordably send humans to Mars. One of the goals of the 2020 mission to Mars is to further the search for signs of past life on the planet. We will e searching for one of the essential building blocks of life, carbon. Here on earth, almost all living things require carbon, so it is safe to believe that if there was ever life on Mars, that it also would need carbon. In 2020 we will be looking for signs of water, carbon, or any biological footprints left behind by forms of past life, along with searching for a special type of sedimentary rock that has been known to hold fossils here on
In 2007, Danny Boyle created a movie that could represent the future of the earth. In Sunshine, the sun is dying, which jeopardizes all life on Earth. The Sun warms the seas, generates the weather patterns, and gives energy to the growing plants that provide the food and oxygen for life on Earth. In Sunshine, the plot follows the 8 person crew of the Icarus II. In 2050, Icarus is the name given to the first human space mission to approach the sun in order to place a bomb into it and reignite it so that it doesn 't die out.
It is a gas giant, 96% of its volume is hydrogen. Saturn has been known since prehistoric times. Greek god Saturn was named after the planet, and ancient Chinese and Japanese culture named Saturn the “earth star”, one of the five elements of nature. Observations of Saturn from a telescope was first discovered by Galileo in 1610, with a 15mm diameter telescope. First photograph of the planet was in September 1979, by Pioneer 11, launched by NASA.
An illustration showed that the moon would slowly be drifting away from the Earth. The inverse square law states that if the moon was half the distance away then the gravitational effect on our tides would be quadrupled or if the moon was 1/3 the distance then the gravitational effect would be 9 times stronger causing us to drown at least twice a day. If the Earth existed more than a billion of years then the Moon should have been inside or touching the Earth. If Humans were a result of evolving there should be at least remains of fossils of our ancestors who were in a different form. For over 2 centuries of digging beneath the Earth no previous ancestor remains have been found.
The moon goes through 8 phases, new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Then it repeats these phases as it goes around the Earth, which takes the moon 28 days. Overall, Mr. Wolf was pretty close to knowing how the moon phases happen. Moon Phases Explanation-Mrs. Challe Mrs. Challe explained the moon phases mostly wrong. She started off by saying that the sun’s shadow blocks the moon.
Magic: “That’s one small step for man, one giant leap for mankind.” These were the words that Neil Armstrong declared when he stepped down from the Apollo 11 spacecraft onto the moon’s surface. A human walking on the moon is no small feat. It would’ve cost more than 100 billion dollars today. The journey itself took a hundred thousand engineers, technicians, and scientists, and even then, they were problems. This 8-day event is a huge marker in history.
