Water is vital for life to occur. Therefore, scientists looking for organics focus on regions and planets where they might form in a practical liquid state. Previously, this was in the habitable zone (CHZ), the region around stars warm enough to sustain liquid water – more specifically, the CHZ around M-dwarf stars. These common stars are much cooler than the Sun, but they make up regarding 70% of the stars in the Milky Way, and most known exoplanets orbit M dwarfs. However, new research has shown that exoplanets outside the CHZ have two main liquefaction mechanisms, which means That life may still be able to thrive, according to the newspaper “Metro”. “As Earthlings, we are fortunate right now that we have the right amount of greenhouse gases in our atmosphere to make liquid water stable on the surface,” said lead author Lujendra Ojha. “However, if the Earth lost greenhouse gases, the average surface temperature of the Earth would be around -18°C, and most of the liquid surface water would freeze completely. A few billion years ago, this already happened on our planet and the surface of the liquid water completely froze.” That, this does not mean that the water was completely solid everywhere, for example, the heat from radioactivity deep in the Earth can heat the water enough to keep it liquid, even today, we see this happen in places like Antarctica and the Canadian Arctic, Where there are large underground lakes of liquid water that, despite freezing temperatures, feed on heat from radioactivity. “There is even some evidence to suggest that this might be happening right now at the south pole of Mars.” Source: Technology News: A new study.. The odds of finding life on other planets are 100 times better. Related news:
