In about five billion years, the Sun will run out of fuel and begin to collapse under its own weight, a process that will heat and expand the outer layers, which will engulf the orbits of Mercury, Venus, and perhaps the Earth. This red giant stage will be followed by a stage in which the envelope will expand freely to form a planetary nebula, with the bare core of what was once the Sun, a white dwarf star, still glowing at its centre.

In 1181, Chinese and Japanese astronomers observed a new star in the sky, or a "guest star," as they called supernova explosions at the time. It remained visible for about six months and is one of nine historical supernovae recorded in the Milky Way, but the only one from the last millennium that still lacked a confirmed counterpart. Now, an international scientific team has found a candidate that fits the 1181 event and poses an unusual scenario, in which the explosion could have been caused by the merger of two white dwarf stars.

After almost a decade of work, an international scientific team has published the most detailed images ever obtained of galaxies, which provide information about their internal workings in unprecedented detail. The images were created from data collected by LOFAR (Low Frequency Array), a network of more than 70,000 small antennas distributed throughout Europe. The images and the associated scientific results have been published in a special issue of the journal Astronomy & Astrophysics, one of them headed by the Institute of Astrophysics of Andalusia (IAA-CSIC).

A Spanish scientific team, headed by the University of Seville and in which the Institute of Astrophysics of Andalusia (IAA-CSIC) and the Calar Alto Observatory (CAHA) participate, has designed and patented a new optical technique that allows detecting the presence of virus in fluid droplets and dry debris on a surface. The results have been published in the journal Scientific Reports (Nature Publishing Group), and the team continues to actively work on the analysis of human samples with SARS-CoV-2.

During the second half of July the Perseids began to cross the night sky. At the moment, only between one and two events can be observed every hour, but the true astronomical spectacle will take place in mid-August, when this meteor shower will reach its maximum activity: in places far from the light pollution of the big cities, up to fifty perseids per hour.

In 2012, a study in which the Institute of Astrophysics of Andalusia (IAA-CSIC) participated published the hypothesis that the planets could influence the Sun: the solar magnetic activity during the last ten thousand years was reconstructed by analyzing the concentration of beryllium -10 and carbon-14 in ice from Antarctica and Greenland and compared with the movement of the planets around the Sun. Coincidences were found that suggested a link, a result opposed to the general conviction that the influence of the planets on the Sun is negligible.

On 26 August 2020, NASA's Fermi space telescope detected a pulse of high-energy radiation that, with a duration of only one second, broke a record: it was the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen. Its study, in which the Institute of Astrophysics of Andalusia (IAA-CSIC) participates, shows that the classification of these bursts according to their duration does not entirely correspond to reality and opens up new scenarios in the death of stars.

The history of science in Spain has never been a subject that has been valued in its fair measure, even by Spanish scientists themselves today. In this talk we will focus on the figure of Azarquiel, a representative of medieval science who, in the opinion of the speaker, is the greatest Spanish astronomer of all time. The aim of rescuing this and other forgotten scientists is to settle, even if only partially, the historical debt we owe them.
Andrea Ghez and Reinhard Genzel were awarded the Nobel Prize in Physics 2020 for their discovery of the massive black hole at the center of the Milky Way. In my talk I will review the history of their research work from a front-line point of view (having worked closely with the two researchers on this topic). I will explain the methods and measurements they used and the strength of their results.

Relativistic jets produced by supermassive black holes are the most energetic astrophysical objects known and can be observed up to enormous distances and very early ages in the universe. This lecture will focus on these objects, and more specifically on their main characteristics and the extra information provided by studying the polarized light they emit, as well as the main questions that remain to be answered to fully understand them.

According to the most up-to-date cosmological model, large spiral galaxies like the Milky Way grew by absorbing smaller galaxies, in a kind of galactic cannibalism that is evidenced by the stellar tidal streams, gigantic structures which are observed around them and which constitute the remnants of their satellite galaxies. But the full story is still mostly unknown, as these star streams are very faint and only the remnants of the most recent mergers have been detected.

MAAT top-level requirements will broaden its use to the needs of the GTC community for a wide range of outstanding science topics that covers the entire astronomy given its unique observing capabilities well beyond time-domain astronomy
MAAT* (Mirror-slicer Array for Astronomical Transients) is proposed as a visitor mirror-slicer optical system that will allow the OSIRIS spectrograph on the GTC the capability to perform Integral-Field Spectroscopy (IFS) over a seeing-limited field-of-view 14.20'' x 10'' with a slice width of 0.303''. MAAT will enhance the resolution power of OSIRIS by 1.6 times with respect to its 0.6'' wide long-slit.

M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent picture of the link between the magnetic fields and underlying dynamo mechanisms, rotation, and activity. For instance, models predict that the maximum magnetic flux a star can generate scales with convective energy stored in its envelope, but no accurate measurements existed until recently.
The Spanish Virtual Observatory (SVO) is organising a VO school at the Instituto de Astrofísica de Andalucía. The school is partly supported by the ESCAPE project and by the IAA-CSIC Severo Ochoa Excellence programme. The Virtual Observatory (VO) is opening new ways of exploiting the huge amount of data provided by the ever-growing number of ground-based and space facilities, as well as by computer simulations.

SUNRISE, a mission designed to study the Sun’s magnetic field from a stratospheric balloon, faces its third flight after its successful trips flying over the Arctic in 2009 and 2013. The instrumentation was recovered in both occasions, and now the mission team focuses on the preparation of the next phase, which will take place in 2021. In late September, the aluminizing of the SUNRISE telescope mirror took place at Calar Alto, a service offered by the observatory that permits to preserve the optimal conditions for observations.

In January 2005, a bright flash was detected in the nucleus of the galaxy in the process of fusion Arp 299-B, which was considered a supernova explosion. However, ten years of observations at different wavelengths have allowed us to witness how the luminous region was lengthening and expanding, and to conclude that it is a jet of material expelled by the galaxy's central super-massive black hole after tearing a star.
Following an open debate, the International Astronomical Union recently recommended that the rate of expansion of the universe, traditionally referred to as the "Hubble Constant", should henceforth be referred to as the "Hubble-Lemaître Constant". In this session we will see why the change of designation was necessary to do justice to the work of Georges Lemaître, one of the fathers of relativistic cosmology, but also the reasons that point out that in reality it is not a constant.

We review the evidence of the existence of methane on Mars and its possible implications.
Galactic superwinds, common phenomena in galaxies, are capable of releasing an extraordinary amount of energy and transporting material over long distances. Their influence on the host galaxy can be of great importance, to the extent that the formation of these "galactic hurricanes" can even determine the life of galaxies. The study of these phenomena provides us with some keys to solving the enigmas of modern astronomy about the evolution of galaxies.
It has been 45 years since Calar Alto Observatory was founded. An observatory that, among its merits, has been one of the main engines of the development of astronomy in Spain and, of course, one of the foundations of the creation of the Instituto de Astrofísica de Andalucía (Andalusian Astrophysics Institute). This year the observatory goes from being Hispano-German to being totally Hispanic, with the incorporation of the Junta de Andalucía as a 50% partner.
At 22:25 in the evening (local time) of December 11 a brilliant fireball crossed the south of Spain. The fireball, which overflew the provinces of Granada and Jaén, could be seen from much of the country. The phenomenon has been recorded from the Sierra Nevada Observatory (Granada), as well as from the meteor detection stations operating under the SMART Project from the observatories of La Hita (Toledo), Calar Alto (Almería), La Sagra (Granada) and Seville.
