This week, the Instituto de Astrofísica de Canarias is hosting the Second SONG Scientific Congress to conclude the first decade of high-level work of this international network devoted to the study of the interior of stars and the planetary systems that surround them. The meeting, which is taking place at the headquarters of IACTEC in La Laguna from 18 to 20 September, brings together more than 50 scientists from Europe, the United States, Australia and China to discuss the latest state-of-the-art techniques in time-resolved spectroscopy and stellar astrophysics.

The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis ofAdvertised on

An international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered the extremely eccentric orbit of a gas giant exoplanet. This world, called TIC 241249530 b, not only follows one of the most drastically stretched-out orbits of all known transiting exoplanets, but also is also orbiting its star backwards, lending insight into the mystery of how these high-mass gas giants evolve into hot Jupiters , with very close and circular trajectories. The study is published in Nature. Within the population of known exoplanets, there are those thatAdvertised on
