  • Astronomy Picture of the Day (APOD) on February 27th 2020

    A recent study analyses data collected at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete reference method to measure the natural brightness of the night sky using low-cost photometers. Of the 44 photometers in the survey, the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands) stands out at the darkest of all the skies analysed. The night sky is not completely dark; even in the remotest places there is a glow in the sky produced by natural components, both terrestrial and extraterrestrial, and by artificial

    The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern Physics at the same time: the problema of Charge and Parity in the strong interaction, and the mystery of dark matter. However, in spite of the high scientific interest in finding it, the search at high radio frequency -above 6 GHz- has been almost left aside for the lack of the high sensitivity technology which could be built at reasonable cost. Until now.

    On May 5th the Earth will pass through the cloud of dust and small fragments of rock which comet 1P/Halley left behind during one of its approaches to the Sun, giving rise to the meteors known as the Eta Aquariids. The channel, in collaboration with the Energy Efficiency Laboratories (EELabs) project coordinated by the Instituto de Astrofísica de Canarias (IAC), will broadcast this meteor shower as part of its activities in “Sounds of the Sky, a Citizen Science project of the FECYT to involve the whole family in classifying meteors, and also to make this task easier for visually

  • First images of DRAGO

    DRAGO, the infrared camera developed by the team at IACTEC-Space of the Instituto de Astrofísica de Canarias, has seen its “first light”. The instrument, placed in orbit in January from Cape Canaveral is in its commissioning phase. The images taken show the mouth of the rio Meghna in the Ganges delta, the largest delta in the world. Even though it is a preliminary test, the quality of the results is well above expectation and show what DRAGO will be able to do once it is fully operational. On January 24th 2021 the infrared camera DRAGO (Demonstrator for Remote Analysis of Ground Observations

  • Training action

    Si hablar en público suele ser un motive de ansiedad, la tensión aumenta todavía más cuando el objetivo es desarrollar una idea compleja en ciencia, como una investigación, un doctorado o nuevos resultados. El veterano curso de la Fundación Dr. Antoni Esteve How to improve your scientific presentations (con más de 25 ediciones presenciales en España y Francia) ha dado el salto en línea con una nueva versión que ofrece numerosas técnicas y consejos prácticos para mejorar las presentaciones orales. Dado que el inglés es la lengua internacional de la ciencia, el curso se desarrolla íntegramente

    In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses. In this context, a team of researchers led by Borja Toledo Padrón, a Severo Ochoa-La Caixa doctoral student at the Instituto de Astrofísica de Canarias (IAC), specializing in the search for planets around this type of stars, has discovered a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years
