We present www.3o4cosas.com, a free educational platform with JavaScript-based simulations designed to teach astronomy, astrophysics, and cosmology. It includes visual, interactive tools on topics such as celestial motion, planetary models, and the future of the universe, making it ideal for secondary education and teacher training. The simulations, designed to be accessible without prior training in physics, have been used in the Peruvian national selection for the International Olympiad on Astronomy and Astrophysics and in general science courses at the university level. We aim to establish the platform as a key resource for educators worldwide, and we welcome feedback and collaboration to adapt the content further for school settings and teacher training initiatives.
