The formation of the Solar System began 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.
This widely accepted model, known as the nebular hypothesis, was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. Since the dawn of the space age in the 1950s and the discovery of extrasolar planets in the 1990s, the model has been both challenged and refined to account for new observations.
The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System. The positions of the planets often shifted due to gravitational interactions. This planetary migration is now thought to have been responsible for much of the Solar System's early evolution.
The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called ices, such as water, ammonia and methane. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.

At 4.6 billion years old, the Solar System is our solid, secure home in the Universe. But how did it come to be? In this episode we trace the system's birth from a thin cloud of dust and gas. Shocked by a nearby supernova, the pull of gravity and natural rotation spun it into a flat disc from which the Sun and planets coalesced. It all happened in the space of 700 million years, during which the planets jockeyed for position, dodging the brutal bombardment of deadly asteroids and setting into the neat, stable system that we now realize might be a rarity in the universe.

Our spacecraft have visited rocky asteroids and icy comets to collect invaluable data about the origin of the Solar System. And the orbits of Kuiper Belt Objects—tiny worlds far from the Sun—reveal that our planetary system had a terrifically violent past, when giant planets changed their orbits, wreaking gravitational havoc. Visualizations from the Academy’s award-winning planetarium show Incoming! tell the story of this ancient interplanetary transformation. - - - The California Academy of Sciences is the only place in the world with an aquarium, planetarium, natural history museum, and four-story rainforest all under one roof.

Where did our solar system come from? The advent of space flight and space-based telescopes gave us unexpected clues to how our solar system began.
--- ABDH Media - Space --- It's astonishing what you can achieve with just a bit of gas and dust. Kate Ravilious guides us through the birth of our solar system It all started with a tremendous bang. Somewhere in our galaxy a star exploded, throwing out masses of gas and dust. This supernova, as these explosions are called, happened about 5bn years ago. The wreckage from the explosion then crashed into a nearby cloud of gas, bringing together the ingredients for our solar system to form. Because the explosion was so energetic it made the dust mixture very hot and things began to cook. Little bits of dust began to cluster, making bigger and bigger lumps, and the mixture began to pull together under its own gravity. Eventually the central lump became so hot and dense that it started to g...

Evolution of the universe predates both the chemical evolution and the evolution of life. In this lecture, Harry J. Lehto, Professor in the Dept of Physics and Astronomy in the University of Turku, Finland, summarises the origin of the critical elements for life, the CHNOPS, and the initial formation of molecules. From cosmological models we can understand the origin of hydrogen and helium. Later hydrogen will be required when water is formed. Helium, which appears quite useless for life, turns out to be a critical factor in the synthesis of carbon leading to heavier elements. The second compound of water, oxygen, is formed in the hot cores of stars. Once these elements get from the stars back into the cool interstellar space they begin forming interstellar clouds, where a vast spectrum ...
Upcoming EU2016 Conference: https://www.thunderbolts.info/wp/2015/12/30/eu2016-home-page/ In 1950, it was expected that space probes would confirm existing concepts about the origin of the solar system, the atmospheres and surfaces of planets as well as the space between the planets. Instead, the subsequent reports announced “surprises,” “unexpected findings,” and things “not well understood.” Numerous examples will be given. Dr. Cj Ransom received his PhD in Plasma Physics from The University of Texas at Austin. He joined an engineering group at General Dynamics in Fort Worth, Texas and developed electro-optics equipment, infrared (IR) detection devices and simulated infrared (IR) guided missiles using analog and digital methods. He also developed non-destructing testing techniques for ...
Take a ride through the solar system.
Pick a star I hope it fits in your pocket.
You know they love you but you just dont fit in.
You're swinging punches boxing shadows eye sockets.
You dance like Marilyn Monroe
but Juliet, where's your Romeo?
They're pushing you, pulling you, streching you.
They're somehow sucking the life out of you.
You're begging them please to stop.
If I could I would but you one hundred thousand stars and put them all in your pocket.
For those rainy days.
You need bitter so the sweet taste sweeter, sweeter still coz sweetness always follows. Those rainy days.
He dances like Elvis Presley
But Juliet he's no Romeo.
They're pushing you, pulling you, streching you.
They're somehow sucking the life out of you.
You're begging them please to stop.
They're mocking you, poking fun at you.
They're laughing, but at you not with you.
You're begging them please to stop, stop, stop, stop.
He sings like Frank Sinatra
But Juliet I'm your Romeo.
They're pushing you, pulling you, streching you.
They're somehow sucking the life out of you.
You're begging them please to stop.
They're mocking you, poking fun at you.
They're laughing, but at you not with you.
You're begging them please to stop.
You're dancing with him and not with me.
I hide it well but it's killing me.
