Edward Guinan and Scott Engle, researchers at the University of Villanova, Pennsylvania, announced the possibility of a primitive life in the icy "super-Earth" known as GJ 699b, which gravitates around the world. Barnard star, located at
They claim that on the planet, also known as Barnard b, temperatures reach minus 170 degrees Fahrenheit. However, this new world, unveiled in November of last year, has the potential to nurture a primal life if it has a large iron or hot nickel core and geothermal activity, argue the astrophysicists.
According to Guinan, geothermal heating could allow the existence of "living areas" beneath the surface, similar to the underground lakes found in Antarctica.
"We know that the surface temperature of the frozen moon of Jupiter – Europe – is similar to that of Barnard b, but due to tidal warming [processo por meio do qual a energia de rotação e translação é dissipada sob a forma de calor no interior dos planetas e luas envolvidos] it is likely that this moon has liquid oceans under its icy surface, "
As Scott Engle observes, Barnard's star is almost twice as old as the Sun: it's 9 billion years old, compared to 4.6 billion Years in our Sun.
"The Universe Planets have produced the size of the Earth long before our existence and even before the Sun exists," he explained.
