Scientists from the Instituto de Astrofísica de Canarias (IAC), in collaboration with the University of Cambridge and the University of California San Diego, detect large amounts of oxygen in the atmosphere of the "primitive star" called J0815+4729. This finding, reported in the journal The Astrophysical Journal Letters today, provides an important clue on how oxygen and other chemical elements were produced in the first generations of stars in the Universe. Oxygen is the third most abundant element in the Universe after hydrogen and helium. It is essential for all forms of life on Earth

The Sun is not the live coal that Anaxagoras described. We can imagine hell in its interior, and we know that there are darker spots on its surface which, when discovered, were shown to be incompatible with the Aristotelian principle of the perfection of the heavenly bodies. We have learned a great deal about our star since then, but even now we do not know the answer to some important questions about the source of energy of our Solar System, the main source of life. These were the words of Jeffrey R. Kuhn, doctor in Physics from Princeton University, and currently Professor at the Institute

This astronomical event will be broadcast live via the channel sky-live.tv in the early hours of January 4th, with the collaboration of the European project EELabs. Together with the Geminids and the Perseids, this is the most intense meteor shower of the year. The three most spectacular meteor showers of the year are the Perseids (in August) the Geminids (in December) and the Quadrantids in the first week of January. Although the Perseids are the best known, the maximum is in a holiday period with mild night-time temperatures, the Geminids and the Quadrantids never let us down, with an

CAPTION: Composite view of particle ejection from the surface of asteroid Bennu on January 6, 2019. This image was produced by combining two exposures taken by the NavCam 1 imager: a short exposure (1.4 ms) showing the asteroid followed by a longer exposure (5 s) to show the particles. First results on the analysis of several particle ejection episodes imaged by the OSIRIS-REx spacecraft have been presented in a Science paper, co-authored by Julia de León and Javier Licandro of the Instituto de Astrofísica de Canarias (IAC). NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu on December

For ten days, more than sixty doctoral students and postdoctoral researchers from different countries participated in the XXXI Canary Islands Winter School of Astrophysics, which this year focused on computational fluid dynamics for astrophysical uses. Its participants, more than 30% were women, which is considered one of the successes of this School of the Institute of Astrophysics of the Canary Islands (IAC). The design of complex algorithms with modern computer architectures and code optimization to achieve maximum performance has a large number of applications for differents fields of

Continuamente se buscan nuevos horizontes y fronteras que superar y se detectan nuevas señales, como las ondas gravitacionales producidas en fenómenos cósmicos masivos, también en el Big Bang. LIGO ( Laser Interferometer Gravitational-Wave Observatory ), proyecto en el que colaboran más de mil investigadores de 20 países diferentes, fue precisamente diseñado para detectar estas ondas. Al conseguirlo en 2016, como resultado de la fusión de dos agujeros negros, este observatorio confirmaba una de las predicciones de Einstein en su Teoría de la Relatividad General. Ahora, a esta colaboración
