A meeting brought together scientists, technologists and institutional representatives to present the latest developments in the La Palma Quantum Interferometer (LPQI) project, outline its next steps and analyse the potential of quantum technologies to drive science, innovation and sustainable development on La Palma. As part of the La Palma Quantum Interferometer (LPQI) project, scientists, technologists and institutional representatives met from 8 to 10 September at IACTEC in La Laguna (Tenerife) to hold the LPQI Workshop 2026, an event at which the latest advances were presented and the

How large can a galaxy grow? This is the question behind a new study led by the Instituto de Astrofísica de Canarias (IAC), in which an international team of astronomers has measured, with unprecedented precision, the size of IC 1101, considered the largest known galaxy in the Universe. The study has been published in Astronomy & Astrophysics. The result confirms that this cosmic giant is even larger than previously thought. The main body of IC 1101 reaches a diameter of around 1.7 million light-years, approximately 10 times the size of the Milky Way. If it were placed between our galaxy and

An international team of astronomers, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the Gran Telescopio Canarias (GTC), has observed a dramatic change in a supermassive black hole. Located about 10 billion light-years away, the object dimmed to roughly one-twentieth of its former brightness in just two decades — an extraordinarily short interval on cosmic timescales. The discovery was made within a collaborative observing framework linking Japan’s Subaru Telescope with the GTC in Spain’s Canary Islands at the Roque de los Muchachos Observatory, in La Palma
