24 planets have been discovered by the researchers with more lively than Earth
In space, There are 24 planets that are likely more suitable for life than in Earth, said by the researchers in a recently published study. These more habitable planets are older, slightly larger, warmer and possibly wetter than Earth.
Two dozen planets identified by researchers, which may have a more suitable position for life than Earth.
A study led by the Washington state University Dirk Schulze-Makuch has recently appeared in a journal of Astrobiology detailing the characteristics of these potentially '' superhabitable '' planets.
According to a report in Astrobiology Web, these more ' habitable ' planets are older, slightly larger, slightly warmer and possibly wetter than Earth.
Some of these orbits may be better than our Sun. Life can also flourish more easily on planets that replace stars with longer lifespan than our sun.
The 24 contenders for superhabitable planets are all more than 100 light years far away, Schulze-Makuch said the study could help focus future observation efforts, Such as NASA's James Webb space Telescope, the LUVIOR space observatory. And from the European space Agency's PLATO space telescope.
'' With the next space telescopes, we will get for detail, so it is important to choose some targets,'' said Washington State University (WSU)'s professor and professor at the Technical University of Berlin, Schulze-Makuch.
'' We have to focus on some planets that have the most promising status for complex life. However, we have to be careful not to look for another Earth because there may be planets that are more suitable than our lives can.''
So, can Human go and live there?
For the study, Schulze-makuch, a geobiologist with specializing in planetary habitability along with the astronomer Rene Heller of the Max Planck institute for solar systems research and Edward Guinan of the University of Villanova, discovered the super habitability criterion and 4,500 known exoplanets beyond our solar discovered system for good candidates.
Habituation does not mean that these planets definitely have life, only condition that would be favorable for life.
The researchers selected planetary star systems with potential terrestrial planets, orbiting within the habitable zone of the liquid water of the host Star, from the Kepler object of interest exoplanet archive of the transplanted exoplanets.
While the Sun is the center of the solar system, its relatively short life span is less than 10 billion years.
Since it took about 4 billion years before any kind of complex life appeared on Earth, many similar stars from our sun, known as G-stars, can run out of fuel before complex life develops.
While the researchers are looking at system with cooler G star, they also observed system with K dwarf star, which are somewhat cooler, less massive and less luminous than our sun.
K stars have a long lifetime gain of 20 billion to 70 billion years. This will allow the planets to orbit along with giving more time to life to carry on the complexity currently found on Earth.
However, in order to be habitable, the planets do not have to be so old that they dissipate their geothermal heat and lack protective geomagnetic fields.
Earth is about 4.5 billion years old, But researchers argue that the sweet spot for life is a planet that is 5 billion to 8 billion years old.
Do these planets have Air and Water?
Size and mass also matter. A planet that is 10% larger than Earth should have more habitable land, which is about 1.5 times the the mass of the Earth, it would be expected to maintain its internal heat through radioactive decay for a longer period of time and also have a stronger gravity to sustain the atmosphere over a longer period.
Water is important for life and the authors argue that it will help a little more, especially in the form of moisture, clouds and moisture.
A slightly warmer temperature, the Earth's average surface temperature of about 5°C ( or about 8° F ), with excess moisture, would be better for life as well.
This heat and moisture preference is seen in cool, dry areas with greater biodiversity in tropical rain forests on Earth.
Of the 24 top planetary candidates, none of them met all the criteria for superficial planets, but none possessed four important characteristics, making it possibly more comfortable for life than our home planet.
Schulze-Makuch said that, '' it's sometimes difficult to express this theory of superhit planets because we think we have the best planet.''
'' We have a large number of complex and diverse life-philosophies, and many that can survive in extreme environment.
It is good to have a favorable life, but that does not mean that we have the best of everything.''
