After Mars, the most study in the possibilities of life outside the Earth has been done on Venus. It has been a matter of debate whether life can exist on these planets or not for a long time. The evidence of life on Mars has been rejected more, than the ray of hope on Venus. This was considered unfavourable to life from the beginning, also gives rise to debate. After discussing the discovery of phosphine last year, a new study has once again raised hopes of the possibility of life on Venus.
A new study has found that the clouds of Venus can filter ultraviolet rays. Due to this, there is a possibility of creating a favourable environment for photosynthesis of the Earth’s fold in the layers of other clouds there. Not only this, the layers of shadows on the planet Venus are sufficiently capable for micro-life to flourish.
Data from so many sources
In a study published this week in Astrobiology, researchers used data from NASA’s Onera, the European Space Agency’s Venus Express and the Japanese space agency JAXA’s Akatsuki missions to draw results that may not be too shocking, but completely There are definitely new ones.
The scope for changing the perception of the atmosphere
The discovery of phosphine gas last year caused a stir. This gas can be made only by bacteria on Earth. But in July last year, amid the phosphene debate, another study reported. It states that the clouds of Venus are so dry that life is not possible there. But a new study seems to be talking about changing this notion.
Water was there for two billion years
Scientists believe without any dispute that the planets Earth and Venus were the same planets at their formation. For two billion years after its formation, the surface of Venus was habitable, and there were also shallow oceans. But with Venus being very close to the Sun, everything changed.
Dry and hot Venus
Being near the Sun, the sunlight absorbed the oceans of Venus. Water vapour in the atmosphere broke up, and hydrogen went into space. Greenhouse gases increase with carbon dioxide without water. Today, the situation is such that the temperature here reaches 462 ° C. There is no water vapour in the atmosphere. This atmosphere contains 96 per cent carbon dioxide, which is 90 per cent thicker than Earth
Interesting turn of the debate
This study has given a new and exciting twist to the debate on the possibilities of life on the planet Venus by claiming that Venus’s clouds provide an enabling environment. According to the study, the process of photosynthesis can happen here not only in the day but also at night because infrared rays and thermal energy keep coming out from the hot surface here.
Apart from this, scientists also claim that there is not much acidity in the clouds here. With this, the activity of water is also not unfavourable for the growth of microorganisms. The upper layer of clouds acts like the ozone layer of the Earth. Researchers believe that in the coming times, missions will be sent to Venus-like Mars and Europa.
