A study of the radio emission of Proxima Centauri, the closest planetary system, opens a new path for the study of exoplanets

For two decades it has been known that the magnetic interaction between Jupiter and one of its largest moons, Io, generates a large amount of radio emission similar to terrestrial auroras (produced, in turn, by the interaction of electrically charged particles from the Sun with the Earth's atmosphere). After the discovery of the planet Proxima b around the star closest to us, Proxima Centauri, a group of researchers from the IAA-CSIC set out to check whether radio interactions also occur in this neighboring solar system. Their finding opens a new path in the study of extrasolar planets.

Triple planetary conjunction: an ideal opportunity to enjoy the night sky

This month the conjunction of three planets of the Solar System takes place: Jupiter, Saturn and Earth will be located approximately in a straight line. The Earth being the closest to the Sun, that means that we can observ Jupiter and Saturn very close in the sky. The separation between the two will be just 0.1 degrees, which is roughly one-fifth of the apparent diameter of the full Moon. This apparent closeness between Jupiter and Saturn has not occurred for 400 years, and will not occur again until March 2080.

RoadMap: studying the ubiquitous yet poorly known Martian dust

Mars is the planet to which the most space missions have been dedicated. A parade of rovers and landers has landed on its surface, and all the images they have sent have revealed one thing: the abundance of dust. No matter which way they looked, Curiosity, InSight, and their predecessors photographed a planet covered in rust-colored dust, not just on the ground, but also in the atmosphere. With Mars being the focus of future space exploration, both robotic and human, it is crucial to improve our understanding of the Martian atmosphere and climate.

The Stingray nebula, the youngest known, is fading

The life cycle of stars has time scales that may seem eternal: a star takes millions of years to be born, and its adult stage extends billions of years. If it is a star of low or intermediate mass, like the Sun, there will come a time when, having exhausted the hydrogen from the nucleus that serves as fuel, it will expand and expel its outer layers; and these, illuminated by the stellar nucleus, will give rise to a planetary nebula. These are very beautiful objects, which expand while dimming their brightness to end up fading in several tens of thousands of years.

Rapid radio bursts detected in our Galaxy

One of the most studied phenomena in astrophysics today are the so-called transients, astrophysical objects that do not present a permanent emission over time, but rather emit light in a brief, intense and sudden way. Among them are the fast radio bursts (or FRBs), which have been known since 2007 but whose origin is still uncertain.

The family of electrical phenomena that occur in our atmosphere, which for centuries was believed to consist only of storm lightning, continues to grow: about three decades ago Transient Light Events were discovered, a series of very fast luminous events related to lightning that tend to happen tens of kilometers above the clouds; and in 1994 terrestrial gamma-ray bursts were discovered, which originate in the upper part of storm clouds and were an unexpected finding, since until then it was thought that gamma radiation only came from outer space.

Magnetic fields, rotation, and activity in M dwarf stars

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 title of this talk evokes a common question in conservation circles, which highlights the privileged place of the Galapagos Islands as a laboratory of evolution and a jewel of biodiversity. A jewel that, like many other natural areas, faces various threats related to human activity.

This talk is based on a travel book about the islands. In it we will see what is so special about the Galapagos, how the species that populate them came about, and why we must love them and, in the long run, save them.

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.

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.

Sierra Nevada Calar Alto

The Sierra Nevada Observatory (OSN) is a high mountain observatory located in Loma de Dilar, in the ski resort of the Sierra Nevada mountain range (Granada). The OSN is operated, maintained and supplied by the Instituto de Astrofísica de Andalucía (IAA-CSIC). It consists of a main building which hosts two Nasmyth optical telescopes of 90-cm and 1.50-m diameter each, as well as a 60-cm IR semi-automated telescope and a 35-cm telescope.

The German-Spanish Astronomical Center at Calar Alto is located in the Sierra de Los Filabres (Andalucía, Southern Spain) north of Almeria. It is operated jointly by the Junta de Andalucía and the Instituto de Astrofísica de Andalucía (CSIC) in Granada/Spain. Calar Alto provides three telescopes with apertures of 1.23m, 2.2m and 3.5m to the general community. A 1.5m-telescope, also located on the mountain, is operated under the control of the Observatory of Madrid.
