A history of the origin and organization of the solar system

Formation and evolution of the Solar System The most widely accepted theory of planetary formation, known as the nebular hypothesismaintains that 4.

A history of the origin and organization of the solar system

The central stellar embryo may still "feed" off the material collapsing around it and continue to grow. Chunks of surviving matter not consumed by the voracious stellar embryo collide, combine, and later form planets through accretion.

The explosive activity can also generate "solar winds" that may affect the weather on Earth. Not so for the Moon, where for millions of years asteroids pounded the surface, creating its peaks and valleys. Like a star, it's primarily made of hydrogen and helium. But Jupiter never heated up and remains a cold, gassy goliath.

The storm is so large that two or three Earths would fit within it. How Did the Planets Form?

Big History Project: Our Solar System & Earth

The cosmic creation of our Solar System New elements, combined with the just-right Goldilocks Conditions came together and formed our Solar System. Radiation from the recent supernova kept the planet extremely hot, its surface molten, and oxygen was non-existent.

Plus, incredibly massive meteorites and asteroids frequently slammed onto the surface — creating even more heat. The Earth got so hot, it began melting.

Heavier material sank to the bottom, lighter stuff rose to the top. This transformation created the Earth's layered core and mantle, crust, and atmosphere.

Even today the Earth undergoes constant change. Shifting, sliding, and colliding tectonic plates "surf" atop its semi-molten mantle. This relentless drifting speeds along at the rate of fingernail growth, yet causes mountains to rise, volcanoes to erupt, and earthquakes to strike.

Finding Earth Letting the Sun take center stage It took billions of years for the Earth to form and settle into orbit around the Sun. But how do we know that? What makes it so? These questions burned and plagued astronomers for millennia. To study the movements of heavens back then, you would look up into the sky.

You would see the Sun and stars revolve around the very spot where you were standing, the Earth — just as Ptolemy did some 1, years ago. This geocentric view, backed by the very powerful religions at the time, endured for more than 1, years until it was toppled by Copernicus and confirmed by Galileo.

The lifecycle of our Sun

Through their observational evidence, and by using the newly invented telescope, they produced data and logic supporting a Sun-centered, heliocentric model of the Solar System. Through these revolutionary findings, geocentrism began to crumble.

In the later s, Newton developed his three basic laws of motion and the theory of universal gravity by combining physics, mathematics, and astronomy. These ideas laid the foundation for our current understanding of the Earth and the cosmos, and helped astronomer Edwin Hubble construct the modern-day Big Bang theory.

Stargazers Ptolemy about 85— Claudius Ptolemy's theory extended the cosmological theories of Aristotle.

Organization of work in preindustrial times

Earth was at a center of a series of concentric spheres containing the Moon, the planets, the Sun, and a final sphere of fixed stars. Copernicus — A Catholic, Polish astronomer, Nicolaus Copernicus, synthesized observational data to formulate a Sun-centered cosmology, launching modern astronomy and setting off a scientific revolution.

Galileo — Galileo Galilei, an Italian Renaissance man, used a telescope of his own invention to collect evidence that supported the Sun-centered model of the Solar System. Sir Isaac Newton — By combining physics, mathematics, and astronomy, Newton developed the three basic laws of motion and the theory of universal gravity.

Henrietta Leavitt — By measuring the amount of time between the fluctuating brightness levels of variable stars, Leavitt discovered that it would be possible to estimate their distance away from the Earth, and possible to map the Universe.

Edwin Hubble — Hubble drew upon existing ideas and evidence to demonstrate that the Universe was much larger than previously thought and proved that it is expanding — laying the foundations for the Big Bang theory. In one second it races around the Earth seven times.

Then in a blink of an eye, light reaches the Moon. Going out to the stars, Astronomers know that by studying Cepheid variables, the fluctuation in brightness of certain stars, we can calculate the star's distance from Earth.

The longer the period of fluctuation, the brighter the star. So even though a star might appear extremely dim, if it had a long period it must actually be extremely large.

The star appeared dim only because it was extremely far away.Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in .

Oct 14,  · History & Origin Of Solar System The formation of Solar System is primarily believed to be based on the nebular hypothesis. As per the hypothesis, the . Introduction A solar system is a star and all of the objects that travel around it—planets, moons, asteroids, comets and meteoroids.

Most stars host their own planets, so there are likely tens of billions of other solar systems in the Milky Way galaxy alone. Solar systems can also have more than one star. Chapter 22 The Origin of Earth and the Solar System Karla Panchuk, Department of Geological Sciences, University of Saskatchewan Outline the early stages in Earth’s history, including how it developed its layered structure, and where its water and atmosphere came from Chapter 22 The Origin of Earth and the Solar System by Karla.
