Más allá de nuestro sistema solar

The video discusses the concept of exoplanets, which are planets orbiting stars outside our solar system. It highlights the discovery of hundreds of exoplanets by astronomers and focuses on the star Glice 581, which has at least five exoplanets. One of these exoplanets is similar to Earth and may contain water, suggesting the possibility of life.
