life on venus in the past

It’s clear that more detailed investigations are needed to verify life on—or above—Venus. This has relevance for assessing the exobiological potential of extrasolar Venus-like greenhouse planets. 'Perhaps life originated in the past when Venus was cooler, with liquid water oceans. Another possibility is that life in Venus’s atmosphere (if there is any) came from Earth. Mars is currently dry and desolate, but in the past was warmer and wetter. The search for extraterrestrial life has largely focused on Mars, but scientists at MIT, Cardiff University, and elsewhere reported surprising findings in September of what may be signs of life in the clouds of Venus. A fundamental question in exobiology remains the degree to which habitats on Venus, past and present, were, or are suitable for life. A 1978 NASA mission to Venus may have overlooked some incredible evidence of life in the planet’s atmosphere. This would make sense for Venus obviously because the atmosphere is just so densely composing carbon dioxide. Cloudy world: a recently-enhanced image of Venus taken by the Mariner 10 spacecraft. Prospects for Life on Venus Fade—but Aren’t Dead Yet. As it heads towards the surface, it sends… Jonathan O'Callaghan Contributor Opinions expressed by Forbes … Like I said before, phosphene is produced on earth by organisms that are living in environments that are very poor in oxygen. Dr Ng: One past indicator of life on Venus was the discovery of an absorption of ultraviolet light in Venus’ atmosphere. 'As Venus heated up the oceans evaporated and the surface became so hot that any life would have been killed, but any life in the clouds would have survived.' Now the spacecraft makes its journey into the planet’s thick, sulfurous atmosphere. It was also caused by an unknown process. If life formed back then, it might have adapted to spread into the clouds. This will require Herculean undertakings, as any actual upcoming missions to Venus are ideas, with no firm plans in place. Researchers poring over archives from previous missions to Venus claim that NASA may have first detected phosphine signatures (indicating potential microbial life) back in 1978, and they just went unnoticed for the past 42 years. Venus also rotates very slowly, taking 243 Earth days to complete a Venusian day. Water is life. Pioneer 13 dropped a probe through Venus's clouds 42 years ago. Venus, roughly the same size as Earth, is often called our sister planet. If rocks from Earth containing microbial life entered Venus’s orbit in the past, this life may have adapted to Venus’s atmospheric conditions. So, just in the past year, we’ve had coming out of the European Planetary Sciences Conference last September, the idea that up until as recently as 750 million years ago, Venus may have had water oceans and a habitable environment before something catastrophic took place. This precious resource was crucial to the evolution of life on Earth. References 1. There is speculation about life existing in Venus' distant past, as well as questions about the possibility of life in the top cloud layers of Venus' atmosphere, where the temperatures are less extreme. The Vatican’s top man on all things outer space has cautioned against getting too speculative about recent findings from a group of astronomers suggesting there could be life on Venus… But today, it's considered inhospitable to life. 3 Life on Venus? In recent times, scientists have wondered if simple life might survive in Venus’ unusually cloudy atmosphere. One should be prudent and adopt a cautious wait-and-see attitude. (Courtesy: NASA/JPL-Caltech) Phosphine, which is a gas produced exclusively by microbes on Earth and considered to be a strong signature of life on other worlds, has been detected in the clouds of Venus. A fundamental question in exobiology remains the degree to which habitats on Venus, past and present, were, or are suitable for life. Q: Have there been any past indicators of life on Venus? Sagan died in 1996, in the midst of a criminally long dry spell for NASA Venus exploration. But the thinking behind life on Venus didn’t disappear completely. High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life. Quick Facts Day 243 Earth days. Shutterstock A truly alien explanation. In the past, the authors of the new paper pointed out, some researchers have suggested the possibility of life in the planet's uppermost cloud layer. How would life survive on Venus? Life could have evolved on Mars, and we may find the fossil evidence of such life. The new findings suggest that if life ever existed on Venus, either now or in the past, it might actually be present in the air itself. Proposed processes included microorganisms as the absorbers. May 22, 2019. Powerful electrical events quickly alter … They often indicate karmic debt. Past life indicators in synastry can be very supportive and loving, but depending on the nature of the planets involved, you can also block each other and bring hard lessons into each other’s life. 2020. It's believed to have had oceans billions of years ago. Grinspoon reacts to the phosphine discovery by saying that it “will force people to take seriously the plausibility of a cloud biosphere on Venus.” If past is prologue, the excitement following the discovery of this malodorous gas will give way to an explanation that doesn’t depend on the presence of life.
