In the scientific community, some believe that finding extraterrestrial life is “likely to last,, while others believe that aliens may be more common than previously thought.
A new study shows that intelligent life is likely to live in a very different star system. Researchers modeled a theoretical Earth to binary star systems – binary stars – and found that 87 percent of these “outer worlds eksen should have an inclination similar to that of Earth, an important component for intelligent life.
“Multi-star systems are common and about 50 [percent] stars have binary stars. Therefore, this study can be applied to many solar systems. ” Gongjie Li, co-author of the study, said in a statement.
In the past such discoveries were made, recently LTT 1445 A b, including a remote rocky exoplanet of three stars. LTT 1445 A b is about 22 light years away from Earth. In 2016, NASA discovered a planet orbiting two stars in the OGLE-2007-BLG-349 system, 8,000 light-years away.
Light years measure distance in space and are 6 trillion miles.
Researchers compared the Earth's slope with the Mars slope, drawing attention to extreme differences between the two planets, and then looked at how Earth would have been if the Earth's 4.4 year-years were in the Alpha Centauri EU system.
Sayısal kullanarak Using numerical modeling in Centauri AB, we demonstrate the following: there is a sharp contrast between the planetary tilt changes of the host star, the planet neighbors Limiting the possible rotation states and the presence of a moon for Earth-like tilt balance Researchers participating in the survey challenge our expectations on earth they imbalance reading inclination. ”
Tik We have simulated how stellar masses, orbital qualities and differences will be around a wide variety of variations with other binary files, Billy said Billy Quarles, lead researcher of the study. “The overall message was positive, but not for our nearest neighbor”
Reaching deeper, the results became more promising and made researchers believe there was a possibility.
“In general, the distinction between stars is larger in binary systems, and then the second star has less impact on the Earth model, Li Li said. “The dynamics of the planet's own movement dominate other influences, and the skew usually has a smaller variability. So, this is quite optimistic. "
The study was published in the scientific journal Astrophysical Journal and funded by NASA's Exobiology Program.
Extensive research published in June found no evidence of extraterrestrial life among more than 1300 stars close to Earth, a prey that lasted more than three years.
A separate study published by the moon indicated that the definition of “habitable zone – – the distance between a planet and the star – was sınırlı limited to that for microbial life,, greatly reducing the number of planets that could potentially host intelligent life.
In October, a former NASA scientist delivered a striking speech in the 1970s that said the space agency was convinced that Mars had “found proof of life Mars on Mars. NASA strongly rejected this claim.
