The continents were formed in some of the exoplanets outermost galaxy 5 billion years before the Land. For life to exist in Land There must be conditions that make it possible. These key elements include a large landmass which, while not essential, is not unnecessary and can help this strange phenomenon thrive. Therefore, the discovery that this galaxy already had exoplanets that replaced continental parts billions of years before our planet formed is surprising. planet.
The latter is suggested by new research from the Cardiff University (United Kingdom). Furthermore, the scientists responsible claim that this would increase the probability of life on exoplanets at the edge of the planet. Milky Way. Life beyond Earth. Plans for this possibility were being considered long before this conclusion was reached. In fact, her presence led astronomer Jane Greaves of the Cardiff University to investigate when the first continents of the continent were formed galaxy.
Thats not all. Research such as the one now published in the Research Notes of the American Astronomical Society They put not only life at stake, but also intelligent and advanced versions of life. In fact, researchers have discovered that the first continents formed on an exoplanet orbiting a star similar to the sun. Specifically, these masses terrestrial They formed at least 2 billion years before plate tectonics began in our world. Based on a sample of 29 stars, Greaves suggests that at least two Milky Way systems may have more developed biospheres than the Land.
The POT discover the planet most similar to Land found outside the Solar System
The POT discover most of the planets similar to the Land outside of our Solar system The Kepler mission of the POT has discovered twin brothers who are mirror images of the marriage between the Land and the Sun. The satellites that orbit around us star In search of new worlds they try to locate the Land within the so-called habitable zone defined around each star, an area where liquid water and perhaps life can exist on its surface. to planet.
Since the mission began in 2009, several headlines have read: “Twin exoplanet discovered Land“. And it is true that many similar planets have been discovered so far. The planet itself POT confirmed this discovery as exoplanet number 1,030. But in this case the key is in the stars, not the planets. “Super-Earths are often discovered in comfort zones around stars, but what is interesting about this discovery is that, in addition to having a size similar to the Landthis planet is also located in a star similar to Sun. This means they are spinning around.” David Barad, researcher at the Astrobiology Center (INTA-CSIC).
Astronomers use a concept called spectral type to understand the temperature of a particular star. Actually, the spectral type can be described as a rainbow that is produced when a star passes its light through a prism or, of course, through the rain. In this case, the experts of the POT They needed to demonstrate that the star orbiting the newly discovered planet (called Kepler-452b) is of type G2, that is, that it has a temperature of about 5 thousand 800, Kelvin about 5 thousand 500 Celsius degrees. Just like ours sun.
