Earth remains the only known living species,media BGR reported. So when looking for extraterrestrial life, it’s easy to think that we should look for galaxies similar to the solar system. But that may not be the case, and a new study suggests that if people want to find extraterrestrial life, they should probably target binary systems.
The study, published in the Astrophysical Journal, focused on the behavior of Earth-like planets in binary systems. The “heart” of the binary system consists of two stars orbiting each other. The study’s arguments are based on computer models that place “extraterrestrial Earth” in a variety of different star systems. Data show that the rocky world in these systems tends to benefit from stable axis tilts. This can play a huge role in ensuring that planets have a predictable and stable climate, which is considered a major advantage of advanced life-form evolution.
The possible planet’s flight was not particularly good when researchers placed the virtual “extraterrestrial Earth” in the habitable zone of the nearby binary system Alpha Centauri AB. When the planet orbits the “B” star, it freezes quickly. When it is placed in orbit around the “A” star, things seem to be better for life. However, because Alpha Centauri AB is a special case in which its star’s orbit is unusually close, the researchers extended its projection to different binary systems, finding that many of them provide life-friendly conditions for virtual “extraterrestrial Earths.”
“We simulated the surroundings of other binary stars, which have a variety of changes in star mass, orbital mass, and so on,” Billy Quarles, who led the study, said in a statement. “The overall message is positive, but not in our nearest neighbors. “
