What can the galactic habitable zone (GHz), a galaxy region in which complex life is accepted to develop further, to teach scientists, to find the right stars that could have habitable planets? This is what hopes for publication in Astronomy & Astrophysics, hopes to investigate a connection between the migration of stars, which is generally referred to as star hike as an international team of researchers, and what this could mean to find habitable planets in our galaxy. This study has the potential to help scientists better understand the astrophysical parameters in order to find habitable worlds beyond the earth and even life as we know them.
For the study, the researchers used a number of computer models to simulate how a stellare migration can influence the place and the parameters of the GHZ. The models included scenarios with and without outstanding migration in order to determine the statistical probabilities for terrestrial (Rocky) planets that are formed in the entire galaxy. The researchers also used a chemical evolutionary model to determine the formation and development of our galaxy, especially with regard to their thickness.

In the end, the researchers found that star migration influences the formation of habitable planets in the outer regions of the galaxy. This is because the star migration leads to a redistribution of stars in the entire galaxy, the team estimates a five -time higher probability of star migration that stars lead to a lack of star hike. In addition, the team found that gas giant planets could influence the formation of terrestrial planets in the inner regions of the galaxy.
In the conclusions: “In this study we have the examination of the parameter room, which defines the galactic habitable zone [European Space Agency] Planetary Transits and Oscillations of Stars (Plato), the ESA Ariel Space Mission and a large interferometer for exoplanets (life). These missions provide unprecedented data on planetary properties, orbital architectures and atmospheric compositions. “
The concept of the GHZ is expanding the long -standing idea of the stellar zone (HZ), which is the specific distance that a planet has to circle its star so that liquid water exists on its surface, which was first introduced in the 1950s. Like all scientific terms, the idea of a GHZ has developed over time since its first introduction in the 1980s, but the overarching idea is that this region consists of heavier elements (ie iron, silicon and oxygen) that are used for forming terrestrial planets such as earth. As stated in this study, the exact size of the GHZ is still being discussed, but the consensus in the scientific community is that the GHz does not exist at the center of the galaxy, since this region houses countless supernovae and other heavenly events that would restrict the habitable planets.

As in the study, there are several ESA missions in the pipeline, the aim of which will be to expand our knowledge of how and where a life finds beyond the earth. For example, the Plato mission that comes onto the market in December 2026 will be the goal of scanning a million stars to observe and identify exoplanets that are known as transit in front of them and is one of the most common methods of discovering exoplanets for exoplanets.
The Ariel mission, which will be launched in 2029, will have the goal of observing at least 1,000 confirmed exoplanets in order to learn more about their chemical and heat -hedgery compositions. Finally, the 2017 life mission started with the aim of examining the atmospheric terrestrial exoplanets in order to identify potential signs of life that are known as biomarkers.
What new discoveries about the migration of GHZ and Stern will researchers do in the coming years and decades? Only time will say it, and that’s why we know!
As always, they continue and continue looking!
