The camera pans out, revealing our protagonist: a small, modest star we shall refer to as Solara. Solara is an infant… actually, she’s just on the brink of coming into life. In the vastness of the universe, we see countless other stars, some bigger, some smaller, some heavier, some lighter. But how does one Solara come into existence? This is the life story of our protagonist.
We owe our existence to the force that keeps us grounded: gravity. Now, imagine a vast, swirling nebula, an abstract painting of myriad colours, from fiery reds and vibrant blues to calming greens—every hue imaginable. This cloud, filled with gas and dust, is where gravity begins its sculpting. While minuscule particles possess only minuscule gravity, over millions of years, these particles become denser and denser, gathering more and more material as their combined gravity increases. After aeons, this process forms a protostar, a nascent star shrouded in gas and dust, patiently accumulating mass.
A few million years pass, and our cute little Solara Protostar is now entering its teenage years, transitioning to a new phase of life. The protostar slowly contracts, its core glowing brighter and brighter, the temperature rising dramatically. Then, something extraordinary happens: nuclear fusion ignites. Deep within Solara’s core, hydrogen atoms are forced together with such incredible force that they fuse into helium, releasing a tremendous burst of energy. Solara has reached stellar adulthood and aims to do great things, like build a solar system.
A billion or so years slip by, and our adult Solara is now beginning to age. The hydrogen fuel that powered it for so long is running low. As Solara approaches this critical point, the
delicate balance between the outward pressure of fusion and the inward pull of gravity is disrupted. The core contracts, growing even hotter, while Solara’s outer layers expand dramatically, cooling and reddening. We see Solara transform into a large, red giant, its surface now a vast, crimson sphere. This red giant phase marks a turning point; for stars like Solara, it’s the beginning of a gentle decline.
Over vast stretches of time, Solara’s outer layers drift away, leaving behind an incredibly dense and hot core—the remnant of our beloved star. This white dwarf, the only thing that remains of Solara, is destined to slowly cool and fade, eventually becoming a cold, dark ember in the vast cosmic graveyard.
But not all stars are granted such a quiet death. Let's turn our attention to Igneel, a blue star far more massive and dense than Solara. Igneel burns through its fuel at an astonishing rate. To compensate, Igneel continues to fuse heavier and heavier elements in its core: helium, carbon, nitrogen, all the way up to iron. As Igneel progresses through these fusion stages, its colour shifts, a visual proof of the changing elements within. Iron, however, marks a dramatic turning point. Unlike other elements, fusing iron requires energy rather than releasing it.
As Igneel reaches this iron threshold, we witness its core collapse in a fraction of a second, triggering a supernova—a burst of unimaginable power that sends gravitational waves rippling across the universe. Light and energy erupt outward, illuminating the surrounding space in a spectacular display. In this breathtaking, catastrophic moment, Igneel’s core implodes and then rebounds outward in a colossal explosion.
Finally, we pull back for a wide shot of the universe, now with new nebulae, newly formed stars, and the remnants of past stellar lives: neutron stars and, if the core was massive enough, a black hole—a region of spacetime so warped that nothing, not even light, can escape.
From the quiet birth in a nebula to the explosive death of a supernova or the slow fading of a white dwarf, the lives and deaths of stars are a cosmic song of creation and destruction, a witness to the awe-inspiring power and enduring beauty of the universe. Each star, a cosmic actor on this grand stage, plays its unique part, leaving its mark on the cosmos.
