Near-Earth object

astronomers call tides are a subtle but inexorable force that have literally shaped most objects in the Universe. And to understand tides, we start with gravity. Gravity is a force, and it weakens with distance. An important thing to note is that we measure gravity from the center of mass of an object, not its surface. One way to think of the center of mass of an object is the average position in an object of all its mass. For an evenly distributed sphere, that’s it’s…

there was a time when neither heaven nor earth existed. Everything was in darkness, unformed and unseparated. The structure of the universe was trapped inside a single egg known as the Cosmic Egg. Within this yolk of chaos grew a giant. The giant was called P’an Ku. He eventually emerges from the splitting in two of the cosmic egg because he grew too large. The half of the shell above him is known as the sky and the other half below him is known as the earth. He then slowly grows taller and…

The concepts Ray Kurzweil puts forth in the documentary The Transcendent Man are both intriguing and frightening. Kurzweil discusses Technological Singularity, also referred to as the “Accelerating Change Thesis”, and it’s meaning as “…a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed…” Many of Kurzweil’s ideas or predictions regarding the changing of our technological world, stemming from…

Violent delights have violent ends "The development of full artificial intelligence could spell the end of the human race” (Stephen Hawking). Hawking divulges that as we approach the singularity, our own creations will render us evolutionarily obsolete. Our great developments over time are the things that have allowed us to make our own tools, languages and commerce but someday instead of creating new technology our innovations may bring us to our own demise. Science fiction writer Vernor…

which is very cold compared to here on Earth. Pluto is so far away from Earth that scientists know very little about what the mysterious planet it is like. Pluto’s orbit is 5,913,520,000 km from the Sun.…

His first stop, earth’s moon. Shoemaker postulated that we could extrapolate our knowledge of earth’s processes to other planets and moons in the solar system. He believed that the earth and moon’s craters were two examples of the same phenomenon. Mapping the moon was something that Eugene did eventually accomplish, however; his larger dream of visiting the moon would have to wait. Shoemaker was diagnosed with Addison’s disease which…

known what the center of the earth is? There 4 ways how scientist found out about the center of the earth ( aka inner core and outer core). Answer 1: Geologists hypothesize that the Earth's center is composed of predominantly iron. The outer portion of the center, known as the "outer core", is thought to be liquid iron. While the interior portion of the center, known as the "inner core" is thought to be solid iron. Answer 2: The main evidence for the structure of the Earth comes from studying…

The planet Jupiter is one of the five objects to be visible from Earth in the solar system. Of these bodies it is the second largest behind the sun. Jupiter is the largest planet in the Solar System with a mass of 1.899x1027kg orbiting at 5.2AU from the Sun. Jupiter is orbited by 67 moons of which the first four are called the Galilean moons as of their discovery in 1614 by Galileo. Jupiter formed about 4.6billion years ago from the cloud of dust and gas that made up the early Solar System.…

stared at the night sky and wondered what the universe looks like up close? If you thought that our world was as small as Earth, that’s nothing compared to the universe that can be explored with a Hubble telescope and the radio telescope. Space craft and technology provides the world with astronomical information, discovering information that is beyond our capabilities on Earth capabilities to discover with our eyes alone. Two major telescopes that have been in orbit around the Earth’s…

658,186 km and Orbit period is 30,687.15 Earth days. Uranus takes 84 Earth days to orbit the Sun, its axis is at 98 degrees, this means that the north and south poles of Uranus lie near the equator of earth. During parts of its orbit one or other of the poles direct face the sun which means the planets get around 42 years of direct sunlight followed by 42 years of darkness. A conclusion may have caused the unusual tilt of Uranus. The theory is that earth-sized planet may have collided with…
