It may be one of the greatest unsolved mysteries in history, and despite more and more evidence and recorded data, there is no clear answer. We talk about life outside the earth. Outdoor life. This topic has inspired some of the most notable movies and books, and it’s no surprise. If anything arouses curiosity in people, it is wondering if we are alone in such a large universe, which seems impossible, but has not yet been proven.
More and more science and research focuses on the research into the world outside Earth. One of these studies has come to light recently, in the hands of the magazine ‘Nature Astronomy’ and under a group of astronomers who have managed. discovered continuous radio signals on a planet located 12 light years from Earth.
Where do these signals come from exoplanet YZ Ceti b and were seen with the Karl G. Jansky Very Large Array telescopes, in New Mexico. The research indicates that the world may have a The magnetic field and the atmosphere: two essential elements for habitation and therefore, the possibility of life. Sebastián Pineda, an astronomer at the University of Colorado Boulder, explained it and convinced him that “the existence of a planet with an atmosphere can depend on the strength of its magnetic field, which acts as a protective shield against the objects of the stars it is coming out. “
Where do these signals come from?
According to a study published in the aforementioned magazine, the signals we have seen can come from interactions between the magnetic field of the exoplanet YZ Ceti and its star, YZ Ceti. An interesting miracle to happen with planets similar to Earth, because it usually happens with large planets, like Jupiter.
Jackie Villadse, a collaborator of the study, explained that the opportunity He must be very close to his star so that their magnetic fields interact with plasma jets, creating those radio emissions. In addition, proximity can also cause auroras in stars, like the northern ones on Earth.
This finding may open the door to other researches about the the discovery of exoplanets with magnetic fields. These are places that are difficult to observe directly and, therefore, experts are looking for indirect methods, like measuring the radio emissions produced by that exoplanet and its star. A method that will allow scientists to explore more planets with the characteristics of Earth and, therefore, habitat.
Another Earth-like world
‘Glise 12 b’ It’s a world of measure similar to that of Earth and get it from your star a similar force that reaches our earth. Therefore, it has become one of the main points that scientists are studying about the possibility of living on planets other than ours.
This was discovered by research led by astrophysicist Masayuki Kausuhara. It has become known that there is 40 light years from Earth, in the constellation of Pisces. Its year is 128 days, with a star smaller than the sun and cold. It is a strong candidate to be habitable because, due to its distance from its star, despite having a cold sun, the best temperature reaches the planet. Considering its size, temperature, and distance from its star, researchers have concluded that this new exoplanet is very similar to Venus.
According to the researchers, it is still too early to know whether Gliese has an atmosphere or not. “Knowing this information is an important step in improving our understanding of habitat.” on planets throughout our galaxy,” said Shishir Dholakia, an astrophysicist at the University of Southern Queensland in Australia who is the principal investigator of another of the groups involved in this work.
