Astrophysicists Surprised by Unexpected Effect of Black Holes Beyond Their Own Galaxies
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…

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,…
Until now, these flows of material had been detected only in other wavelength ranges, such as X-rays or the visible, depending on the phase in…
A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active…
Nature magazine has published a surprising study about the giant, ultra-hot planet WASP-76b in which researchers from the Instituto de Astrofísica de Canarias (IAC) have…
The universe 13,000 million years ago was very different from the universe we know today. It is understood that stars were forming at a very…
