THE STORY OF OUR SOLAR SYSTEM

Believe it or not, our solar system, like a child, was born one day and then grew and grew into what it is now.  Learn the story of our solar system below.

6.2 billion years ago

IN THE BEGINNING…

In this laboratory of molecules and space matter, physics takes over.  The stellar nursery coalesces into a gravitational center, a collapsing cloud full of energy, magnetic fields, and turbulence.  Matter accelerates faster and faster until a stellar mass is reached.  The dust within the mass will heat, and when the core temperature reaches about 2,000 Kelvin, the resulting object will be a nascent protostar.

Twinkle, twinkle

Remnants of a supernova will generate and eject a variety of stellar materials.  Over the course of tens of thousands of years, these materials will eventually coalesce into molecular clouds, or stellar nurseries, a birthing ground for a new star.

The dust settles

The planets, and other extraterrestrial objects such as asteroids, form stray discs of dust. Electrostatic forces, or sticky carbon coatings, make dust particles stick together to form clusters, which in turn form rocks. Like the star, mutual gravity causes these rocks to come together, eventually to form planets. This 'coming together' of material is a process known as accretion.
