On September 14, an international team of astronomers claimed to have found the existence of a gas called phosphine in Venus’s harsh acid clouds. The international team of scientists first discovered phosphine molecules on Venus using the James Clerk Maxwell telescope in Hawaii and confirmed it using the modern Atacama Large Millimeter / submillimeter Array (ALMA) telescope. ) in Chile.
This is considered a shocking finding, since phosphine gas is produced only by bacteria that thrive in an oxygen-deficient (anaerobic) environment. The presence of this gas is considered an indication that microorganisms may be present on Venus.
The discovery of phosphine gas in Venus’s atmosphere is considered an indication that microorganisms may exist on this planet.
Despite being close to Earth and most clearly visible in the sky in the form of Saturn and Pluto, Venus is not the focus of Mars-like search for extraterrestrial life. In fact, the dense atmosphere and the location close to the Sun make astronomers think that life cannot exist on this planet.
So, right after this study was published, scientists around the world asked: How can microorganisms appear in a harsh habitat like Venus?
A series of theories have been put forward by scientists to answer the above question. Most recently, a study recently published in The Astrophysical Journal Letters confirmed that life on Venus may originate from Earth.
Specifically, scientists at Harvard University said that a comet or asteroid passing through Earth’s atmosphere unintentionally ‘brought’ some bacteria from our planet during the journey. its.
Do the meteors act as ‘incubators’, carrying life from planet to planet?
It is known that the aforementioned hypothesis was made after scientists studied the event that a meteorite with a size of 0.3 m, weighing 60 kg flew over Australia in July 2017. At that time, this small asteroid formed a glowing ball of fire over Australia’s southern and eastern regions. Interestingly, however, this asteroid did not plunge directly to the ground. Instead, it just grazed Earth’s atmosphere for about 90 seconds, then resumed its indeterminate journey in the solar system.
According to researchers at Harvard, theoretically, a meteorite has the ability to ‘pick up’ bacteria while in the Earth’s atmosphere and then ‘transport’ them to another planet. Calculations from the research team also showed that the small asteroid, when flying through the Earth’s atmosphere in 2017, brought about 10,000 microorganisms into the universe. This means that a certain asteroid brought the materials to form life from Earth to ‘neighbor’ 154 million kilometers away from us.
According to the team, this is quite possible, when during the past 3.7 billion years, at least 600,000 meteors have passed past the upper atmosphere of the Earth. One of the asteroids carrying microorganisms from this Earth may have collided with Venus later, causing life to begin appearing on this planet. Many previous studies also showed that some types of bacteria can survive in space for many years thanks to their ability to withstand cosmic radiation.
