Amongst the tons of galaxies, lies a beautiful one, home to an abundance of gas and dust. The spiral arms owe their structure to the dwarf galaxies sucked in by the Milky Way. The center, with millions of stars surrounding the black hole, powerfully outshines the dull mass of hydrogen gas spiraling around it. Orbiting the Milky Way, distorted by its tight grasp are tiny galaxies full of stars. In the arms of this galaxy lie hundreds of young stars. Surrounded by intense clouds of gas and dust, these stars delicately balance themselves between gravity and fusion. Few of them are sucked in by the giant galaxy, resulting in the formation of new arms.

The shock wave ripples through the galaxy sprinkled space, each of them thousands of light years wide. It looks on as the remnant grows smaller, its center dominated by the eerie glow of the neutron star. Reflecting the failure of the stellar wind to whip away its mass, the strong density of the neutron star emits strong jets of radiation right through its core. As the shock wave travels further away, the remnant lies there, one amongst many, spinning its life away.

And when the shock wave hits the Milky Way, the galaxy’s balance, built on millions of years is tipped.
Thousands of stars are squeezed mercilessly.
A young star at the far end of the galaxy’s arms, triggered by the shockwave, begins to collapse under the force of its own gravity. The increasing speed, fueled by the weight upon itself, spreads out the surrounding envelope of thick gas into a wide disc. The heat at the center increases tremendously and only the fittest of elements survive the drastic change of events. Feeding on the nearby gas unfortunate enough to be near it, the star grows in size and density. The turbulent atmosphere collides several atoms into tiny bulks of mass that are bound to the collapsing star. Dust particles floating around and molten metal stick together and gradually grow in size, exhibiting boiling and violent surfaces. The gas and dust blown away from the sun moved towards the end of the solar system, where the temperatures drop. Out of reach of the angry Sun, the water here quietly turns to ice to be later pulled by gravity into chunks of icy rocks. In the chaos near the sun, molten metal spins faster and faster. Continuously attacked by rocks, its surface registers blows all over. Gradually growing in size, they take their time to shake off the fright. The outer layers cool down while the inner layers remain hot and liquid. With the demise of chaos, planets gradually fall into pace to orbit the Sun.
Rocks too small to be called planets and too huge to be dust are left behind. Floating in the direction of the gravitational pull of planets, these rocks roam around the space. However, ever since Jupiter came into being, its strong gravitational pull prevents the formation of planets in between Mars and itself. The tiny rocks in between the two planets collide often to form asteroids, creating a firm circular orbit for themselves. Jupiter’s gravity, however, was too strong for them to compete with and slowly, they found themselves being pulled away, directed every random way.

Few of them hit earth, the water in them thus escaping.
And, from the ashes, rises the very first instances of life.
