¿De qué COLOR son las ESTRELLAS?

The video explores the relationship between star color and temperature, highlighting how mass influences star characteristics. It explains that larger stars emit more energetic blue light, while smaller stars emit red light. The sun, being average in size, emits yellow light. The video also discusses the formation of elements post-Big Bang, noting that initially only hydrogen and helium existed. Stars later formed heavier elements, contributing to the universe's composition. Today, hydrogen and helium make up a small percentage of the universe, with the rest being dark matter and energy.
