Science Pocket | The Colors of Stars

Prompt

Create an original English science voiceover of about 37 seconds: starting from the red, yellow and blue-white stars in the night sky, explain how a star's color relates to its surface temperature, and point out that its brightness also depends on its size and distance. Use a light, accurate, curious natural voice with no music; deliver a playable MP3.

Playable MP3, 37.0 seconds, voice only — no music.

Measured on the delivered file: 37.04 s, mono, 44.1 kHz, 128 kbps MP3, −17.4 LUFS integrated, true peak −1.9 dBFS (no clipping), 0.6 MB.

Script as recorded:

Look up on a clear night. The stars aren't all the same color. Some glow red, some yellow, some blue-white. That color is a thermometer. Red stars are the coolest, around three thousand degrees Celsius. Yellow stars, like our Sun, sit near six thousand. Blue-white stars burn above twenty thousand. But color isn't brightness. A star's apparent glow depends on how big it is, and how far away it is. A modest star nearby can outshine a giant far off. And a faint point you can barely see with the naked eye may be a thousand times more powerful than our Sun. Every point of light is a distant sun.

Verification note: length, format, loudness, peak and the absence of clipping are measured. The automated transcription/listening check was unavailable in this session, so the voice's tone and pronunciation were not machine-verified — the input text was submitted exactly as written above and the TTS model reads it verbatim. If you want a different read (warmer, more playful, or slower), I can re-record from the same script.
