A team led by a researcher at the IAC and the University of La Laguna (ULL) has accurately measured the variation of oxygen abundance along the disc of our Galaxy.

The European Solar Telescope (EST) is a project led by the Instituto de Astrofísica de Canarias (IAC) to construct the largest solar telescope in Europe with a diameter of 4m, at one of the two observatories in the Islands. Its main purpose will be to study phenomena such as sunspots and solar flares, with unprecedented accuracy, and a resolution of a few tens of kilometres at the surface of the Sun. The EST will allow us to better understand the emission of large quantities of electrically charged material, which can cause problems with our systems of communications. The model of this

El eclipse solar de ayer, que pudo observarse en su totalidad en Estados Unidos continental, fue retransmitido en directo a través de la web STARS4ALL en colaboración con el canal sky-live.tv desde el pueblo de Mackay, Idaho, gracias a la expedición liderada por Miquel Serra-Ricart, investigador del Instituto de Astrofísica de Canarias (IAC). El eclipse también pudo observarse parcialmente desde España, especialmente en las Islas Canarias, donde pudo verse una mayor fracción del disco solar ocultado por La Luna, entre un 42% (La Palma) y un 33% (Lanzarote).   El astrofotógrafo Daniel López

More than a hundred people form this municipality on La Palma could make this annual visit to the main telescopes of the observatory.

The Instituto de Astrofísica de Canarias recovers this American woman asronomer as a character in a multimedia play within an outrreach project whose aim is to stimulate scientific careers for women, and to point up their role in Physics and Astronomy.

On August 21st there will be one of the most anticipated total solar eclipses in recent years: the great American eclipse. The band of totality will cross the United States diagonally from west to east More that 100 million people should be able to watch the eclipse directly.
