Where did our solar system come from.
Birth of the solar system story map.
It might have been a supernova explosion pushing a lot of its heavy element wreckage into a nearby cloud of hydrogen gas and interstellar dust.
About 4 6 billion years ago this gigantic cloud was transformed into our sun.
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.
The solar system is enveloped by a huge bubble called the heliosphere.

Approximate positions available between 1900 to 2100 date range.
Some five billion years ago in a perfectly ordinary place in the galaxy something happened.
Birth of the solar system about 4 5 billion years ago a supernova exploding star at the edge of our galaxy is thought to have sprayed superhot dust and gas into space and caused a neighbouring.
Visualize the orbits of the main solar system objects in an interactive 3d solar system simulator.
The processes of solar nebula collapse and accretion explain why there is so much space in space where we find the various types of planets and other small bodies and why the planets all lie in about the same plane and orbit the sun in the same direction.
Birth of a solar system just like ours.
The formation of a solar system.
The advent of space flight and space based telescopes gave us unexpected clues to how our solar system began.
The solar system as we know it began life as a vast swirling cloud of gas and dust twisting through the universe without direction or form.
Made of charged particles generated by the sun the heliosphere shields planets and other objects from high speed.
The hubble space telescop delivers something rare to the human eye.
The processes that followed gave rise to the solar system complete with eight planets 181 moons and countless asteroids.
The formation and evolution of the solar system began 4 5 billion years ago with the gravitational collapse of a small part of a giant molecular cloud.
Life a chance to look back in time.
