Researchers from the leading Max Planck Institute achieved an epoch-making scientific breakthrough that sheds light on the earliest chemical processes in the Universe. On August 4, 2025, the expert team managed to reproduce the helium hydride ion (HeH⁺), considered the first molecular structure formed after the cosmological primordial moment.

The precise scientific simulation recreated the extreme physical conditions that existed more than 13 billion years ago. Through innovative experimental techniques, specialists reconstructed the chemical transformations that mark the beginning of stellar and galactic formation.

The study results, published in a specialized scientific journal, provide an unprecedented view of the so-called "cosmic dark ages". The achievement not only confirms theoretical assumptions but also opens new horizons for understanding the origin of matter and primary interactions in the Universe.
