The measurements of this key climate variable, obtained from telescopes on the ground, agree with the measurements made from satellites and show a period of stability

The telescopes may form part of the future Cherenkov Telescope Array in the Northern Hemisphere (CTA-North) at the Roque de los Muchachos Observatory.

On Wednesday 20th April there was a scientific outreach event where several astronomers showed us some of the mysteries of the Universe

The Calar Alto Legacy Integral Field Area Survey (CALIFA) has released to the world public all of the data assembled over 6 years of work. The data of more than 600 galaxies are accessible for anyone interested at http://califa.caha.es/DR3 . The astronomical community thus obtains free access to the largest dataset of spatially resolved properties of galaxies ever obtained. CALIFA provides a unique way to learn about the evolution of galaxies. While we ourselves live in a specific galaxy, the Milky Way, there are many more galaxies out there, siblings of our own. A favorite analogy of the

A team of International astronomers, led by members of the Instituto de Astrofísica de Canarias, has measured for the first time the mass of an ultra-diffuse galaxy using the Gran Telescopio CANARIAS (GTC)
