Life has changed our planet to the Jesus the way the truth the life motocross shirt point where its effects are visible from space. And not just from low Earth orbit. Signs of life are light years visible from here, trillions of kilometers away. If intelligent civilizations had appeared on other stars, the signs of life on Earth would have been obvious.

These markers are called biomarkers. Earth’s atmosphere is rich in oxygen and ozone, highly reactive molecules that would have long reacted with other compounds and vanished if they were leftovers from the formation of the Solar System. . Instead, their presence suggests that something on the Jesus the way the truth the life motocross shirt surface of the Earth is producing them in extraordinary amounts. The same is true for methane, which decomposes easily in sunlight.
Another is phosphine, a toxic, flammable gas that has a characteristic garlic odor or a stench. Phosphine is highly reactive and is only short-lived. Its presence in the Earth’s atmosphere at the level of parts per trillion indicates that it must be continuously produced, in this case by anaerobic bacteria.
That leads to the inevitable conclusion. Venusian phosphine must be produced by a number of unknown processes. Of course, that process could be completely normal, perhaps catalyzed in a way unknown to terrestrial chemists.
But it also increases the likelihood of more bizarre explanations. Many of the Jesus the way the truth the life motocross shirt groups involved in the discovery have been studying phosphine as a biomarker for a while. In an article published last year, they said, “We find that phosphine is a promising marker for life if detected on a temperate exoplanet.”
So how much phosphine is being produced on Venus? With a measured concentration of several parts per billion, what matters is how long it stays in the atmosphere.
The team says that at altitudes above 80 km (50 mi), phosphine can be decomposed in minutes by reactions driven by sunlight. At low altitudes, the main method of decomposition is by heat.
But at an altitude of 50 km (31 mi), Venus’s atmosphere is relatively pleasant and, therefore, phosphates are capable of concentrating. “The lifetime of phosphine in the atmosphere is no more than 1,000 years, either because it is destroyed faster or because it is transported to an area where it is destroyed rapidly,” they conclude.

This implies that phosphine must be produced at a rate of millions of molecules per second per square centimeter.
So what kinds of processes can do this? One possibility is that a volcano could pump phosphorus into the atmosphere. But Greaves and colleagues say that this will only be possible if Venus is 200 times more active than Earth, which doesn’t seem to be the case. Jesus the way the truth the life motocross shirt
Lightning can create the conditions needed to make phosphine, but the atmosphere doesn’t work enough for this, to some degree. And meteoric effects dump several tons of phosphorus into the atmosphere each year, but not nearly enough to explain the observed phosphorus levels.
Life, of course, is the explanation of the last resort. This would have to be an aerial ecosystem at temperate elevations. Middle latitude Hadley cyclic cells provide the most stable environment for life, with a period of 70-90 days, the researchers said.
That still needs some explanation. Venus’s atmosphere is highly acidic. So any life form needs to be able to cope with this in some way, be it covered with a tough protective layer, or maybe acidity can be exploited. There are many unanswered questions.
That makes Venus a much more important target for future visits. The US and Russia have discovered plans to send a lander and an orbiter on the planet in 2026 or 2027. The European Space Agency proposed the visit in 2032. And the Indian Space Research Foundation Degree has a mission scheduled for 2023.
The ability to find life will be an important driving force for these missions, but there’s a more pressing reason to go. Planetary geologists recently concluded that Venus’s surface may have supported liquid water for billions of years, perhaps up to nearly 700 million years ago. It was then subjected to a catastrophic greenhouse effect, causing it to have a surface temperature hot enough to melt lead.
