An international team composed of Drs. Sylvain G. Korzennik, from the Center for Astrophysics | Harvard & Smithsonian , and Antonio Eff-Darwich Peña, from the University of La Laguna and the Instituto de Astrofísica de Canarias, has published a pioneering study aimed at improving our understanding of the Sun’s internal structure. The work, published in The Astrophysical Journal , stands out for its use of exceptionally long helioseismic time series, exceeding twenty-five years of continuous observations, to analyze the deepest layers of the Sun. Helioseismology is the study of patterns of

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has achieved its first scientific results, with four articles published today in the journal Astronomy & Astrophysics and one more accepted for publication. The data confirm its ability to detect Earth-like planets in the infrared for the first time with a precision better than one metre per second. One of the papers, led by IAC researcher Alejandro Suárez Mascareño, confirms the presence of a

Ultra-faint dwarf galaxies, among the tiniest and faintest galaxies known, may hold the key to understanding one of the Universe’s biggest mysteries: the true nature of dark matter. A new study reveals that even a single collision between dark matter particles every 10 billion years — roughly the age of the Universe — is enough to explain the dark matter cores observed in these small systems. These galaxies, which contain only a few thousand stars, are dominated by dark matter and have relatively simple evolutionary histories. That makes them ideal cosmic laboratories for testing theories
