- Is Alien Life Possible, Venus Phosphine Discovery: Astronomers Have Found Signs Of Life On Venus Planet? All You Need To Know What The Discovery Of Phosphine Means,
- NASA will send one flagship and two discovery missions to study on Venus planet
The answer to the question of whether or not there is life on any planet other than Earth is being explored for centuries. In this series, scientists have claimed that phosphine gas has been found in the atmosphere of Venus. It arises from a biological process or a biological process. This discovery has rekindled the possibility of being an alien in the universe. The NASA chief has described this discovery as 'the most important discovery ever' in the search for life beyond the earth. We have told you through five questions that why should you be excited about this discovery and what will happen next?
What have scientists found on the planet Venus?
- In the discovery published in Nature Astronomy, researchers have claimed that a gas named phosphine has been found in acidic clouds in the atmosphere of Venus. Phosphine on Earth is made up of microbes that can survive without oxygen. It is a gas originating in industrial processes.
- The gas has been discovered by Jessica Dempsey, deputy director of the James Clerk Maxwell Telescope in Hawaii. He told, “This gas you find on swamps and decomposable objects. Anaerobic life like microbes get out of our air and freeze on clouds.”
- Phosphine is also found in the air planes of the planets Guru and Saturn. However, there are some chemical processes that cause them. These processes are neither possible on Earth nor Venus. For this reason, scientists feel that it can be a sign of life.
What does this search mean?
- This means two – 1. There can be living microbes. But it is not on the planet Venus but in its clouds. We know that Venus's surface is not conducive to any life. The temperature in the clouds where this gas was found was 30 degrees Celsius. 2. These microbes can be formed due to geological or chemical processes that we do not see on Earth and we cannot understand.
- Dr. Dempsey says that we cannot claim 100% that we have found life there. But it cannot be said that there is no life there. This is a promising discovery. We do not know yet because of the phosphine gas we have got there.
- Plenary scientist Stephen Kane of the University of California, Riverside, says that we have not seen phosphine being formed by biological processes on Earth. We do not even know the geological reason. But it cannot be said that this happens everywhere.
What is life like when there is phosphine gas?
- It is too early to say anything at this time. If life is not found on Venus, then there will be a completely different reason for the phosphine gas to be there. Not at all like Earth. However, microbes that have been found there also occur in extreme conditions on Earth – such as on geothermal pools. They can survive in an environment with five percent acid.
- In comparison, Venus clouds are 90 percent acidic. Professor Jean Greaves, who led the international research team, said that if a life existed there, there is no easy way to experiment on it.
So what is the reason for getting excited about this discovery?
- NASA boss Jim Bridestein has described this discovery as the biggest achievement in the search for life beyond the earth. The results have not yet been confirmed. It is a very complex case for phosphine to be found in Venus's atmosphere and claim a sign of life from it. If it is a symptom of life, then there should also be signs of other chemicals that indicate the existence of life around it.
How will scientists find out if this is really life or something?
- Professor Greaves says that no one can claim the results so far. For this, we have to send a spacecraft. Samples will have to be collected. Only then will we be able to know whether life exists in any form or not.
- NASA has approved proposals for two discovery missions and a flagship mission to be sent to the planet Venus over the next decade. The search will be done on Venus using an orbiter in the flagship mission. This orbiter will be a Teflon-coated balloon, glider and lander. In both missions, phosphine as well as phosphorus acid will also be searched, which will show that the gas originated from non-biological process.
