The study, published in the Astrophysical Journal, is based on observations of the expanding remnant of Tycho’s supernova

The Cabildo of La Palma, the Town Council of Puntagorda, the Instituto de Astrofísica de Canarias and the TMT International Observatory have signed a framework agreement which indicates the principles and the areas of collaboration required to implement this scientific project on the island.

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.
