While some in the scientific community believe that finding extraterrestrial life "will probably take a long time," others believe that extraterrestrials may be more widespread than previously thought.
New research suggests that intelligent life is likely to inhabit a star system drastically different from ours. The researchers modeled a theoretical Earth in binary star systems – those with two stars – and found that 87 percent of these "exosomes" should have an inclined axis similar to Earth, an important ingredient for intelligent life.
“Multi-star systems are common and about 50 [percent] stars have binary satellites. So this study can be applied to a large number of solar systems, "said study co-author Gongji Li in a statement.
These types of discoveries have been made in the past, including most recently LTT 1
Light Year measures space in space and equals 6 trillion miles
Researchers compare the Earth's branch to the inclination of Mars, noting the extreme differences between the two planets, and then looking at what Earth might be like if it were in Alpha Centaur AB's system, 4.4 light-years from Earth.
"Using Digital modeling in α Centauri AB, we show the following: there is a sharp contrast between the variations of planetary inclination depending on the receiving star, the planetary neighbors limit the possible states of rotation for stability of the obliquity of the Earth and the presence of the moon can destabilize the hair, ie.
"We simulated what it would be like around other binaries with multiple variations of star masses, orbital properties, and so on," said Billy Quarls in a statement to the principal investigator. " was positive, but not for our closest neighbor. "
Going further into the deep space, the results become more promising, which makes researchers think this is possible.
" Generally, the split between the stars with bigger in binary systems and then the second star has a smaller effect on the model of the Earth, "added Lee." The planet's own motion dynamics dominate other influences and the inclination usually has less change. That's pretty optimistic. "
The study was published in the Astrophysical Journal and funded by NASA's Exobiology Program.
An extensive study published in June found no evidence of extraterrestrial life among more than 1,300 stars in close proximity to Earth, hunting, coyote o covers more than three years.
A separate study published this month drastically reduced the number of planets that could lead an intelligent life, noting that the definition of "habitable zone" – the distance between the planet and the star – "is probably limited to that of microbial life . "
In October, a former NASA scientist published a stunning option, saying he was convinced that the space agency" found evidence of life "on Mars in the 1970s. NASA strongly denied this claim.
