Our moon could have saved the life shortly, say astrobiologists




<div _ngcontent-c16 = "" innerhtml = "

Almost half a century after astronaut Buzz Aldrin of Apollo 11 admired the" terrific desolation "of our moon, two astrobiologists now claim that the lunar surface has been liquid for a short time could be water, a magnetic field, and an incredibly smooth life.

The Moon is among the most dangerous real estate in our Inner Solar System, in a newspaper just published online in the journal Astrobiology by Washington State University (WSU) Astrobiologist Dirk Schulze-Makuch and Ian Crawford A professor of planetary science and astrobiology at the University of on London claims that this microbial life may have occurred as early as 3.5 billion years ago, or during two separate 70 million years earlier, window of habitability 9659003] Moon surface conditions could have supported simple life forms shortly after the Moon approached 4.47 Billions of years ago, and again during a peak of volcanic activity about 3.5 billion years ago, say the authors.

Schulze-Makuch and Crawford write that volcanic outgassing on the lunar surface could have formed pools of liquid water and an atmosphere that is dense enough to hold them there for millions of years , And the authors characterize this epoch as potentially habitable.

During this period of the late heavy bombardment of the inner solar system, it is quite possible that cyanobacteria or organic matter were released from the Earth's surface and sent in a spiral to the lunar surface. 19659008] "There could actually have been microbes that thrive in water basins on the moon until the surface is dry and dead," said Schulze-Makuch in a statement.

Today the moon is inhospitable to the definition of. As the authors write, the moon has "no significant atmosphere, no liquid water on its surface, no magnetosphere to protect its surface from solar wind and cosmic rays."

Every life would be long gone. But which regions would look for microfossils best?

"In the underground we find hydrated paleo-regolith layers between lava flows", Schulze-Makuch told me.

Some researchers have postulated that life could have evolved on Earth in just 10 million years. So, according to the authors, there is a possibility that life has even evolved in these hypothetical liquid-water lunar surface pools.

Such claims are not as farfetched as they were ten years ago. This is because, as the authors note in their work, recent studies show that the Moon's mantle may even be as rich in water as the Earth's upper mantle.

The early moon could also have protected a significant if not volatile atmosphere from the moon's solar wind through a magnetic field.

If so, the authors argue that the likelihood of microorganisms "surviving in terrestrial meteorites hitting the moon is enhanced by the presence of even a faint lunar atmosphere." This is because such an atmosphere would slow down

Although the Moon is among the most worrying real estate in our inner solar system, Washington State University (WSU), the astrobiologist Dirk Schulze-Makuch, was published in a newspaper just published in the Journal Astrobiology and Ian Crawford, professor of planetology and astrobiology at the University of London, claim that this is microbial Life may have already taken place 3.5 billion years ago. Or in two separate 70 million years early windows of habitability.

Moon surface conditions could have supported simple life forms shortly after the moon formed about 4.4 billion years ago and during a peak of volcanic activity about 3.5 billion years ago
