The Impact of an Asteroid on Earth Asteroids 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
Rocks In our solar system, there are a vast variety of space rocks. Space contains comets, asteroids, and meteors that rush through space, but don’t make it to Earth because they burn up along the way. This is due to the amount of friction that is produced on its journey through space. Comets, asteroids, and meteors are only a few objects that orbit through space and in our solar system. As a result, these various space rocks fly throughout our solar system, creating a bunch of chemistry. Comets
Observations by NASA, have shown that asteroid AG5 could hit Earth in 2040. Though there is only a 1 in 500 chance the asteroid will hit Earth, scientists, are not certain of this calculation due to their lack of knowledge of the asteroid’s mass, orbit, and material composition. Therefore, astronomers and agencies, such as the UN, are already taking action. In fact, the UN has even suggested using nuclear weapons against the asteroid. If such an asteroid were to impact a city it could result
by an asteroid colliding with Earth. One major piece of evidence for this is a giant crater (150 km wide) that lies just off the Yucatan Peninsula, which could have been caused by the collision. There were high amounts of Iridium (a metal that is very rare on Earth’s surface but more common in asteroids) and fractured crystals found near the crater. Therefore, an asteroid impact caused the dinosaur extinction. According to PBS.org, the levels of Iridium found near the crater is 30 times higher
device that Philae used, he says, and the team needs more time to work out which molecules it detected.” Another theory which closely ties in with the impact of either a Comet or Asteroid hitting Earth is the disappearance of dinosaurs some sixty five or sixty six years ago. It is inferred in the events where Earth was hit dinosaurs were not the only species to disappear, the fossil record shows numerous other species of the era disappearing as well. The impact essentially changed evolution forever. According
universe and the reliability of that found knowledge will also be discussed and assessed. The Hubble Space Telescope, named after Edwin Hubble, is an operational telescope orbiting outside the earth’s atmosphere at about 600 km above the surface of the earth. Funded for construction in the 1970s and built by NASA, it was scheduled to launch in 1983. Due to technical difficulties the eventual launch was on the 25th of April, 1990. The Hubble Space Telescope is known as the most useful cosmology tool in
The first three chapters of A Brief History of Time cover a variety of topics. In chapter one, Stephen Hawking tries to provide a single theory to describe the entire universe. Chapter two describes some of the ideas that scientists, mathematicians, philosophers, and physicians of the past had about gravity and theories of motion. The third chapter in the book talks about the work of many scientists of the past concerning whether the universe is expanding or not. In each chapter, Stephen Hawking
Space debris is the collection of useless objects in orbit around Earth. It includes all from erosion, spent rocket stages, old satellites, collisions, and fragments from disintegration. A large number of technical studies are currently developing concepts of active removal of space debris to protect space assets from on orbit collision. Since orbits overlap with new spacecraft therefore debris may collide with operational spacecraft. Space debris is important and a global cooperation is needed to
essay: settlement on space Setting settlement is the leading man living permanently outside the Earth. There many reasons to leave our home and find place to keeping our human race, because humans believe that one day the world will probably not suitable to live anymore. For example, the expansion of the population of the human civilization, and how to survive after the disaster on earth or in the Earth atmosphere. It also includes the quest of resources that begin running out and not enough to the
This article was published on the Scientific Daily on the 23rd of December. It was about the discovery of two brown dwarfs by scientists Alex Wolszczan, Evan Pugh, and Penn State. Brown dwarfs are objects in space that sit between the lines of being a star and a planet. This object is dim and hard to distinguish from low mass stars at the early stages of the dwarf’s life. They are often called failed stars because they start their life the same way as regular stars. However, in some stage, they
acting on and upon us all the time. One fundamental force is gravity. Gravity (also known as gravitational force) is the force of attraction. Every object in the world that has mass exerts a pull-otherwise known as force, on other mass ["Forces of Attraction."]. Gravitational pull increases and decreases depending on the amount of mass, and how close objects are. ["Weight, Mass and Gravity."] [See Fig 1.]. In this way, gravity has played a large part in contributing to the creation and development of
of the engine for loose objects and unwanted materials. See to it that all loose objects, parts, tools and equipment are removed from the engine intake and even in front of the air intake area of the engine to be operated. Check the drain ports for fuel, oil and hydraulic leaks from the engine that might cause bigger problem like engine fire or damage due to fluid leaks. Be sure that the aircraft is cleared and that there are no unwanted persons or vehicles in or near the dangerous areas which
one must know the basic definition of the two terms. Mass is typically defined as a measurement of how much matter in in an object or amount of inertia it holds. While weight is a measurement of how hard gravity pulls on the object. The mass always contains the same amount of matter however, the amount an objects weighs may fluctuate due to the gravity. The weight of an object depends on where it is, whereas mass always remains the same; mass does not change given the location in which it is found
There is no dark side of the moon. The moon goes around the earth, and they both orbit the sun. Different parts of the moon are light during different parts of each month. The dark part of the moon isn’t always the same part, it varies depending on the phase of the Moon. The second myth is that Venus and Earth are identical, but they aren’t because Venus is the hottest planet in our solar system and Venus goes counter clockwise and Earth goes
finally measuring the angle of intersection by a protractor. 5(b). Explain why this ecliptic path exists. Ecliptic is the apparent path of the Sun’s motion. Because the Earth is circling around the Sun, the path of the sun is observed as circular on Earth. This path stays relatively constant throughout years because the orbits of Earth and other planets in our galaxy lays on the ecliptic plane, which is defined
The Moon The Moon is the only natural satellite of Earth: orbit: 384,400 km from Earth diameter: 3476 km mass: 7.35e22 kg 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
temperature changes. This can take place by three processes. These three processes are known as conduction, convection, and radiation. When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while others make poor conductors of heat or excellent insulators. Silver, copper, and gold make excellent conductors
From ancient cultures interpreting these near-Earth objects as signs of disaster, to 18th century Europeans studying their paths, to even the extinction of the dinosaurs, comets and asteroids have always been prevalent in the majority of Earth’s history. These objects have intrigued the human race for generations, and continue to do so today. These similar subjects of fascination have many unique and interesting characteristics and a rich history with Earth. A comet is composed primarily of ice and
A Meteor will Strike the Earth and Destroy All Life Forms “With millions and millions of meteors hurtling around in our solar system, there’s always a chance that one could hit Earth at any moment. But what would be the consequences and how would the Earth be affected if one does happen to hit? If an object from space hit the sea, a huge tidal wave would be formed, hundreds of meters high, which would leave most of the world under water for a period of time, destroying and killing everything
