El origen cósmico de los átomos. Hablamos con Enrique Nácher y Sergio Pastor

Cuando decimos que "somos polvo de estrellas", no es una metáfora: es una realidad. Los átomos que forman nuestro cuerpo y todo lo que nos rodea se originaron en distintos procesos cósmicos a lo largo de miles de millones de años. Tras el Big Bang, el universo produjo hidrógeno, helio y trazas de litio. Más tarde, en el núcleo de las estrellas, la fusión nuclear generó elementos más pesados como el carbono y el oxígeno. Al morir, algunas estrellas explotaron en supernovas, formando elementos aún más pesados como el oro o el uranio. Otros se forjaron en colisiones de estrellas de neutrones, eventos extremos que también enriquecen el cosmos. Hoy, incluso somos capaces de crear elementos artificiales en laboratorios. Esta historia fascinante es la que cuentan Enrique Nácher González y Sergio Pastor Carpi, investigadores del IFIC (CSIC - UV), en su libro "La formación de los elementos químicos".
