Subtitles (50 segments)
- [Narrator] Like fireflies on a still summer night,
they gently dot and illuminate the infinite velveteen sky.
Stars.
Be they millions or billions of years old,
are all born in nebuli, clouds of dust
and mostly hydrogen gas.
Within these stellar nurseries,
stars begin life as protostars
or hot cores formed by the collection
and collapse of dust and gas.
