Fractal nebula

Open Supernova ↗
Supernova · Fractal Nebula preset with the demo track

The star sits inside a glowing fractal nebula: fine blue, cyan and violet filaments that surround it and turn slowly around it. The nebula stays behind the explosion and shows in the dark space around it, so the star keeps its own colors. Switch it with Fractal Nebula in the Nebula section, or pick the Fractal Nebula, Star Nebula or Deep Nebula preset.

  • The bass swells the glow and thickness of the nebula, each beat sends a bright ripple out from the star through the filaments, and the highs make points in it twinkle. At silence it keeps drifting gently.
  • Intensity sets its brightness and Density how much of the sky it fills. Detail adds finer branching, Zoom scales the clouds, Twist turns tangled wisps into broader strands, and Drift sets how fast it turns.
  • Nebula Color keeps its own cool blue or takes the star's Color Theme. Camera Distance, under Camera, pulls back to give the nebula more room.
  • Quality trades sharpness for frame rate; choose Low on a slower computer.
  • Below 1, Background Opacity fades the nebula with the background; at 0 only the star remains.

Interesting facts

A supernova is the catastrophic death of a star — either a massive star collapsing under its own gravity or a white dwarf detonating after pulling in too much material from a companion — briefly outshining entire galaxies. BeamTracer's supernova is an audio-reactive explosion scene built for visual impact, not a physically accurate model of stellar collapse.

  • There are two very different triggers. Core-collapse supernovae happen when a star roughly eight or more times the Sun's mass runs out of fuel and its core suddenly collapses; Type Ia supernovae happen when a white dwarf siphons matter from a companion star until it passes a mass limit and detonates in a runaway thermonuclear reaction.
  • We are made of the debris. Supernovae forge elements heavier than iron and scatter them, along with lighter elements built up over a star's life, into surrounding gas and dust — material that later seeds new stars, planets, and, eventually, the atoms in our own bodies.
  • The explosion leaves a remnant behind. A core-collapse supernova can leave behind an ultra-dense neutron star or, for the most massive progenitors, a black hole; the Crab Nebula's central neutron star spins about 30 times per second.
  • Some have been visible in daylight. Chinese, Japanese, and Arab astronomers recorded a "guest star" in 1054 CE bright enough to see in broad daylight for weeks — the supernova that produced the Crab Nebula. SN 1987A, in 1987, was the first supernova visible to the naked eye since the 1600s.
  • A supernova can briefly outshine its whole host galaxy. For weeks to months, the explosion can radiate as much light as billions of ordinary stars combined, which is also why distant Type Ia supernovae are used as reliable "standard candles" for measuring cosmic distances.

These details are summarized from NASA Hubble's guide to stellar explosions, NASA's overview of the Crab Nebula, and NASA's astrobiology explainer on how stars build the elements we're made of.

Quick start

  1. Start the demo track, choose a local audio file, or enable a live input.
  2. Try a preset or style first, then open the section for the part of the image you want to change.
  3. On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
  4. Use Reset to Defaults whenever you want to return to the original look.

Audio modulation

On a control with Assign modulation, select the activity icon to open Modulate with. Choose a named source, or choose — None to leave the control unmodulated. After you assign one, its name appears below the slider; select that name to edit the route, or use Clear modulation to remove it. The slider track shows the live signal reaching the control.

Tips for a better audio visualization

  • Use bass for the largest orbital or camera motion and highs for stars, sparks, or glow accents.
  • Try assigning Bass to Cylinder Radius, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
