These 24 planets may be better places to live than Earth, say astrobiologists

Astrobiologists have identified 24 exoplanets that are not only potentially habitable, they are potential Portable, A demonstration of more suitable conditions for life than what is found on earth.

The modern saying among the environmentally conscious is that there is no Planet B, but a new one Paper Published in Astrobiology suggests otherwise. A research team led by Dirk Schulz-Machuch of Washington State University in Washington has identified 24 exoplanets with conditions that could make them more suitable for life than Earth, making them “superhable”. Unfortunately, all of these exoplanets are more than 100 light-years away, so anyone wishing to get out of this part of the planet should not pack their bags yet.

And just for being crystal clear, this does not automatically mean that life exists on this world, it does mean that these planets may be habitable, or in this case, superfatable.

Written by Rene Heller, an astrobiologist at the Max Planck Institute for Solar System Research and co-author of the new study. Identical paper Back in 2014. Halver, along with John Armstrong, co-author of Weber State University, argues for existence. Portable world, Astronomers said, should be in search of this imaginary class of objects. The authors listed some requirements for inclusion along with a potential candidate. The new work expands on this idea, with a proposal for a more refined set of superheroities, with a list of 24 potential explanatory candidates.

In order for exoplanets to be superhable, they must be older, larger, heavier, warmer, and wetter than Earth, and ideally located around stars that have a longer lifespan than us. So yes, according to new research, not only is the earth inferior, our sun is also inferior.

Indeed, we like to think that our sun is a bee’s knee, but it has a relatively short lifespan of 10 billion years. Considering the 4 billion years it took for complex life to emerge on Earth, it is conceivable that many stars like our Sun, called G-Stars, would end before the distribution of complex life. As a result, the authors say, we should be on the lookout for dwarf stars located in liquid water-friendly habitable zones that are colder, smaller and less bright than G stars, and shine for 20 billion to 70 billion years. The red dwarf, if you are wondering, is not included because this class looks like a star Super rash for life, Given their all-frequent-frequent solar outbursts.

As the new study points out, slightly older planets are more likely to live than Earth. As the planets age, “with the results of global warming and atmospheric composition, the fatigue of heat generated internally can eventually bring cooling,” the authors write. Earth billion. Billion billion years old, but from a probabilistic point of view, planets aged up to billion billion and billion billion years are more habitable.

About 1.5 times the mass of our planet and up to 10% larger, the superhubble planets are larger and heavier. Such planets exhibit more habitable terrestrial surfaces, but only in the presence of other important criteria: plate tectonics sufficient to form large landforms such as continents. The authors argue that the superfarable world should also have plenty of water and plenty of archipelago. Slightly heavier planets also mean stronger gravity, which helps maintain the atmosphere for longer. Importantly, these planets should also have strong protective geomagnetic shields.

According to researchers, on the subject of the atmosphere, superimposed planets should deplete oxygen between abundant moisture, clouds and moisture and between 25% and 30% (Earth’s atmosphere is made up of 21% oxygen). These planets should also be warm, with an average surface temperature of about 8 degrees Fahrenheit (5 degrees Celsius) higher than Earth (well, at least today – a little higher on this). The idea here is that, with the extra moisture, these planets will have wider tropical regions and less cold and dry regions.

Like Earth, superhubble planets must have a large moon at a medium distance. Our moon, in addition to creating ocean tides, slows down the Earth’s rotation (would be significantly longer without days), and it makes stable asons tuo, keeping our axis tilted over time.

Equipped with this criterion, scientists took a look at 4,500 well-known exoplanets to see how many people might actually qualify because they were potentially superhighble. Of these, 24 were different, but did not meet all of the listed criteria for superhubility. An exoplanet, designated KOI 5715.01, exhibits the three criteria listed, which is any exoplanet. To be clear, many parameters, such as atmospheric oxygen, plate tectonics, geomagnetism, and natural satellites, are currently beyond our ability to detect. In addition, only two of these planets, Kepler 1126b and Kepler-69C, are scientifically valid planets, the rest of the confirmed uncertified Kepler jects are on the list of objects. As a result, some of these “exoplanets” may not even be planets.

The new paper “provides a good theoretical background to the many possible circumstances for the habitable world, the supremacist planets,” Abel Mandez, director of the Planetary Habitat Laboratory at the University of Puerto Rico in Arecibo, wrote in an email. “It is not possible to identify such planets in the current Exoplanet databases because we have little information about them. However, the authors identified some with the required characteristics, but not all, ”said Mandez, who was not involved in the new research.

There are other limitations to consider as well. The authors are naturally biased towards Earth-like conditions, providing the only known example of our planetary habitat. Life can spread in situations that are not yet understood, and it is important to keep that in mind. That said, the authors considered the planets in orbits around the K dwarf stars, which, to be fair, is beyond our comprehension.

New paper suggests superhubular planets should be larger and heavier than Earth, but other research suggests that many of these planets should be The world of water, I.e., an exoplanet fully executed by an ocean. It is obviously not good for ecological diversity and is a serious barrier to habitat. This is not necessarily a deal breaker, but it does suggest that superfedable worlds, if they exist, are exceptionally rare.

In view of the numerous problems caused by human-induced climate change on Earth, the authors listed warm temperatures as a criterion – a sensitive topic. But as Schulz-Makuch explained in an email, we should not confuse these two very different things.

“Global warming would be a really bad thing for the current Earth, as we already have an established biosphere and a way of atmospheric circulation, and as a result of change, extreme weather can put a lot of stress on the biosphere, resulting in extinction events.” “In addition, it will raise sea levels and carry valuable habitat to land areas and coastal areas and bring more stress to many parts of the biosphere.”

At the same time, however, if we start from another planet, ideally a slightly larger, “then” higher temperature With More moisture than the earth can be very beneficial. “This is exemplified by the diversity of our current rainforests and the Carboniferous Period, when our planet was rich in both biomass and biodiversity,” he said. Without the necessary moisture, however, we would go into “warm deserts like Atacama, with no more life.”

We are also unaware of the potential knock-on effects of these conditions. They look good on paper, but the reality may be quite different, as these environmental characteristics can lead to a collective result in conditions that are completely unsuitable for the spouse. Still, this is an exciting and exciting study, as it suggests the best conditions for life elsewhere in the cosmos.

Thanks to upcoming tools such as NASA’s James Webb Web Space Telescope, Levier Space Observatory, and ESA’s Space Telescope, we’ll test some of the ideas suggested in the new paper.
