¿Por qué Colocamos Telescopios en el Espacio?

The video explores why the night sky appears dark despite the presence of numerous stars. It explains that the universe had a beginning, which limits the number of stars visible in all directions. The expansion of the universe causes distant stars' light to redshift beyond the visible spectrum. Cosmic background radiation from the Big Bang is detectable, but not visible to the naked eye. The video concludes that the night sky's darkness is due to the universe's finite age and expansion.
