Gas is essential to the process of forming a galaxy. During the first stages the amount of gas present determines the number of stars which will be in the galaxy. The galaxies with active nuclei (AGN) are those with a region of intense brightness in their centres. This brightness is produced by the presence of a supermassive black hole whose gravity makes it accumulate matter around it, in a process known as accretion. Supermassive black holes cause the surrounding gas to heat up, and some of it is driven towards the outer part of the galaxy (feedback effect). Until now it was believed that

On January 21st the Moon will again pass through the Earth0s shadow, acquiring the coppery glow characteristic of lunar eclipses. The eclipse will be visible from the whole of America, and from Atlantic Europe, where we will be able to see the phase of totality of the eclipse, although with the Moon low over the western horizon. This phenomenon will be broadcast live from the Teide Observatory on January 20th-21st, via the sky-live channel, with the collaboration of the European project STARS4ALL. In addition the eclipse will occur at the first full moon of the year, which will also be a

An international team of astrophysicists that includes researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has uncovered an enormous bubble current being ‘blown’ by the regular eruptions from a binary star system within the Andromeda Galaxy. The results have been published today in 'Nature'.

Researchers at the University of Oviedo, in collaboration with the Instituto de Astrofísica de Canarias (IAC) have discovered and characterized a planet in the habitability zone of a red dwarf star. It was detected using the method of transits.

The Instituto de Astrofísica de Canarias (IAC) and the Museum of Science and the Cosmos (MCC) of Museums of Tenerife, have produced the astronomical calendar “100 Square Moons” for 2019 which can be consulted and downloaded in digital format.

The best time to observe the first meteor shower of 2019 will be the night of January 3rd to 4th. The astronomical event will be broadcast live from the Observatorio del Teide (Tenerife) and Higuera la Real (Badajoz), with the collaboration of the European STARS4ALL project and the initiative promoted by the Junta de Extremadura, "Extremadura, Buenas Noches".
