Punch through our solar system's protective bubble, and your first encounter wouldn't be another star. The void is a wasteland of billions of unseen, freezing planets wandering the dark alone.
The space between stars is filled with the interstellar medium—a diffuse, cold mixture of hydrogen, helium, and cosmic dust. Drifting in this darkness are these rogue planets. Violently ejected from their home solar systems during chaotic early formations, they are unbound to any star and remain frozen in perpetual night. They are practically invisible, detectable only when their gravity briefly magnifies the light of a background star.
The closest stellar stop would be the Alpha Centauri system, located 4.37 light-years away. Rather than a single sun, a traveler would find a triple star system. The two main stars, Alpha Centauri A and B, orbit each other closely, bathing their surrounding space in the glare of two suns. The third, Proxima Centauri, is a small red dwarf swinging in a wide orbit. Orbiting Proxima is at least one Earth-sized exoplanet, Proxima b. On its surface, the red dwarf would loom large in the sky, casting a permanent, crimson twilight over the landscape.
Further into the galaxy, the dark void gives way to stellar nurseries. These are massive clouds of gas and dust spanning light-years across. Under their own gravity, pockets of gas collapse and ignite into newborn stars. The intense ultraviolet radiation from these young stars sculpts the surrounding dust into towering, jagged formations, such as the famous Pillars of Creation.
Deeper exploration would reveal the violent ends of stellar lifecycles. A traveler might encounter a pulsar—the crushed, spinning core of a dead star, firing twin beams of radiation across space like a lighthouse. If a ship traveled thousands of light-years to the center of the Milky Way, it would reach Sagittarius A*, a supermassive black hole. There, extreme gravity bends light itself, warping the visual field into a distorted ring of glowing gas and stretched background stars.
