In 1998, the journal Nature published a seminal letter concluding that the mysterious polarization signal that had been recently discovered in the light emitted by…
The black holes at the centers of galaxies are the most mysterious objects in the Universe, not only because of the huge quantities of material…
An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science Institute…
An international team of astrophysicists led by the Stellar Astrophysics Group of the University of Alicante (UA), the Instituto de Astrofísica de Canarias (IAC), and…
Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic…
At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region…
An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) Žofia Chrobáková, a doctoral student at the IAC and the…
A recent study analyses data collected at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete…
The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern…
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface…
During the past 25 years astronomers have discovered a wide variety of exoplanets, made of rock, ice, and gas, thanks to the construction of astronomical…
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the…
The gravitational force in the Universe under which it has evolved from a state almost uniform at the Big Bang until now, when matter is…
At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure…
An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun,…
It was found using observations made with the Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory, (Garafía, La Palma, Canary Islands), and…
An international team of researchers, led by the Instituto de Astrofísica de Canarias (IAC), has confirmed the existence of resonant cavities above sunspots. These results,…
