Proof Of Alien Life? The Truth About What Lurks In Venus' Atmosphere!

If you ask anyone whether life 
exists on other planets and moons,   The answer you’ll probably 
get is a confident “yes!”  Going back generations, we’ve been introduced 
to a wide range of extraterrestrials, good,   Bad and evil. Their presence makes up a 
large part of our entertainment and culture,   And us Earthlings seem to have an unfounded 
belief that we are not alone in the universe. But that extraterrestrial presence on 
regular display in movies or games is,   Of course, a fiction. No alien life 
beyond Earth has ever been found;   There is no evidence that any non terrestrial life 
has ever visited our planet. It’s all a theory. This does not mean, however, that the universe is 
lifeless. While no clear signs of life have ever   Been detected, the possibility of extraterrestrial 
biology – the scientific logic that supports   It – has grown. That is perhaps the biggest 
achievement of the growing field of astrobiology. Later this decade, NASA will launch 
its DAVINCI mission — short for Deep   Atmosphere Venus Investigation of Noble gases, 
Chemistry, and Imaging — to collect never seen   Before observations of our torrid sister planet. 
As laid out in a new paper by mission researchers,   The probe will help answer elusive 
questions: Did Venus harbor oceans?   Was it habitable? Did it ever host life? 
What, exactly, is happening on its surface? On a Venusian day in 2031, at sharp noon, the 
DAVINCI spacecraft will drop a three-foot-wide   Titanium sphere through Venus' thick 
clouds. It will ingest gases. It will   Run experiments. It will endure extremes 
of heat and pressure. It will show us what   Venusian mountains actually look like. If 
all goes as planned, just a single hour of   Observations will transform our understanding of 
Venus and finally reveal its past and secrets. *Intro* Before we begin, let’s be clear. DAVINCI 
is not the first to set foot on Venus.  The first spacecraft to set mechanical feet Venus 
was actually in the 1960s and '70s, the former   Soviet Union's Venera probes. They plunged through 
the planet's punishing atmosphere, with a handful   Even sending back data from its rocky surface. In 
December 1970, for instance, the Venera 8 lander   Transmitted atmospheric data for more than 
50 minutes after its turbulent touchdown.   These early missions provided an important 
lesson: Venus is like a massive pressure cooker. Venus is the third brightest thing in the 
sky, but our view of it is blocked by a   Thick atmosphere, and despite the 
strange and scorching conditions,   Venus shares a surprising 
number of features with Earth. Although the planet is the second closest planet 
to the sun, it's by far the hottest of the eight   Worlds in our solar system. Its thick atmosphere 
is mostly made of carbon dioxide with clouds of   Sulfuric acid, which traps the sun's heat 
and creates a runaway greenhouse effect.

And now, researchers have made an unexpected 
discovery that could be a potential game   Changer in our search for extraterrestrial life.
All thanks to a phosphine gas discovery on Venus.  Phosphine is considered to be a biosignature. 
A biosignature is any substance – such as an   Element, isotope, or molecule – or 
phenomenon that provides scientific   Evidence of past or present life.
Other elements that are biosignatures   Are carbon dioxide or nitrous 
oxide, also known as laughing gas.  On Earth, phosphine is produced 
by certain types of bacteria. This discovery was unexpected and a 
potential game changer. The presence   Of airborne phosphine is a little like spotting 
a lighthouse during a torrid storm on the seas:   A signal that life is in the neighborhood. But if, indeed, living organisms are 
floating in the dense air of Venus,   It would enormously strengthen the 
argument that life isn't a cosmic miracle.  For decades, scientists have pursued life in 
space in three major ways. One is to simply   Search for it which is the motivation 
for sending many of the rovers that   Crawl across the Martian surface. A second 
is to try to tune in to alien radio signals.   And a third is to use telescopes to examine the 
atmospheres of planets and moons for biomarkers:   Gasses produced by life. Which is also what 
the James Webb Space Telescope is doing. What makes the discovery of phosphine in Venus' 
air so compelling is that the researchers have   Racked their brains trying to come up with ways 
to explain its presence without bringing up the   Term “life”. They've considered the likelihood of 
weird chemical processes in the atmosphere that   Could produce it or the possibility that it was 
spewed out of volcanoes below. Even the reactions   Caused by meteors that blaze through the clouds or 
the chemical effects of lightning were considered.  But the scientists couldn't find a 
plausible non-biological explanation. Nonetheless, they remain cautious. History is 
full with claims of extraterrestrial biology that   Later proved suspect or just plain wrong or even 
false, from the canals on Mars to the squiggly   Microscopic features seen in a Martian meteorite. 
Everyone who's claimed to have established the   Existence of life elsewhere has been challenged 
and proven wrong. Science urges us to believe   That our world is the only place in the universe 
where life is known to exist. To prove otherwise   Is a huge goal, and the proof needs to be 
indisputable. Like Keke Palmer in Nope.   The brother-sister duo basically risk their lives 
to get a clear photographic proof of the alien. But Venusian life, could it even 
exist under such hellish conditions?  For decades scientists assumed Venus 
was a sterile hell and largely ignored   It in favor of Mars or several of the 
water-rich moons of Jupiter and Saturn. But not all scientists. Planetary astronomer David 
Grinspoon, of the Planetary Science Institute,  

Has persistently championed the idea 
of paying greater attention to Venus.   He pointed out that at 30 miles above the surface,   The cloud temperatures drop to roughly 
the same as on a fall day in New York.   The idea that some microbes could be floating 
in these extraordinarily dense and temperate   Clouds isn't so outrageous then. Such organisms 
could be the leftovers from simple life that may   Have been spawned during the billions of years 
that Venus had oceans, vast seas that eventually   Boiled away. Or they would be the microscopic 
survivors from a world that slowly burned. But we can't yet rule out the more 
dramatic outcome — the possibility that,   At long last, we've proven that we 
have company in the cosmos. Yes,   They're microscopic and live an 
incomprehensibly dull existence.   But unlike everything else we've yet 
found in the heavens, they're alive. Many simulations of Venus' evolution predicted 
it had an ocean for some 2 or 3 billion years.   That's a lot of time for potential life to evolve.   Out in the deeper cosmos, other exo-Venuses 
might harbor similar environments.  Through all the chaos, one message 
remains clear. We have to know our Venus.
