Amid efforts to find alien life, scientists have not yet confirmed the existence of an extraterrestrial civilization. Findings of a new study suggest this has something do with the element phosphorus lacking in the cosmos.
Life-Giving Phosphorus
Phosphorus is the 11th most common element on Earth, and it is fundamental to all living things. Phosphorus is one of only six chemical elements on our planet that organisms depend on.
"[Phosphorus] helps form the backbone of the long chains of nucleotides that create RNA and DNA; it is part of the phospholipids in cell membranes; and is a building block of the coenzyme used as an energy carrier in cells, adenosine triphosphate (ATP)," NASA said.
Astronomers have been hunting for phosphorus in the universe because of the role it plays in life on Earth. If the element is lacking in other parts of the cosmos, it could be difficult for alien life to exist.
A new study presented at the European Week of Astronomy and Space Science meeting now suggests that life as we know it is more unusual than previously thought because the universe substantially lacks phosphorus.
Phosphorus From Supernovae
Study researcher Jane Greaves, from the University of Cardiff, and colleagues, found that the reason our planet got enough of the element is because it is close enough to a supernova.
Phosphorus is formed in supernovae when massive stars explode at the end of their lives, but the researchers found that the typical supernova may not provide the right conditions to forge the element. Earth just happened to be in close proximity to the right kind of supernova, making it unusually lucky.
The researchers made their conclusion based on observations of two supernova remnants, the Crab Nebula and Cassiopeia A (Cas A). The found that Cas A appears to have more phosphorus than Crab Nebula. The researchers theorize that the latter had more reactions that made phosphorus because it was denser or more massive.
The findings hint that material blown out into space may dramatically vary in composition. The researchers said that some of the phosphorus-bearing minerals such as those in meteorites that came to Earth may have been reactive enough to contribute to the making of proto-biomolecules.
If phosphorus comes from supernova and travels across space in meteoritic rock, the researchers wondered if young planets near the wrong kind of supernova may find themselves lacking in reactive phosphorus.
"In that case, life might really struggle to get started out of phosphorus-poor chemistry, on another world otherwise similar to our own," Greaves said.
“...and should stop our very childish squabbling over exercising power over our fellows.”
Good luck with that.
Cain sort of blew that one out right off the bat.
Things don’t just evolve around everything. Extinctions are common.
My question is, if the earth was substantially already formed when the supernova went, where is the remnant of that supernova today? They don’t go up in a puff of smoke.
Now, that’s profound.
Earth just happened to be in close proximity to the right kind of supernova, making it unusually lucky.
Yeah. Luck had nothing to do with it...
The people who analyze the facts rather than only use their feelings.

Whatever that means ...
Maybe if I typed slower you would understand.
No slower or faster would not help much, however coherent sentence might.
We keep telling ourselves that we are a mature social order when in fact we are merely self delusional infants.
“Phosphorus is the 11th most common element on Earth, and it is fundamental to all living things.”
We only know of exactly one example of life existing so far and it invariably needs phosphorus, so therefore any other hypothetical life will need phosphorus? Seems like the premise is coming from an example of one.

“Phosphorus is one of only six chemical elements on our planet ...”
“Chemical element”?
As opposed to a non-chemical element?
On the other hand - if one believes in evolution, why would a presence of phosphorous be one of the keys? Things would just evolve differently without it.
...
I have a feeling your definition of evolution doesnt match the definition of evolution.
Definition of evolution is fine.
Understanding of chemistry is the problem.
Yup, true. There is no such thing as luck anywhere in the universe, not even in Vegas, since God set it all in motion. Probably why we thank God, not luck, when we win there.
Not criticizing you, TB, but agreeing 100%. What else is a Christian to do? Thanks for the reminder.
As stated earlier fracking is like lighting farts
I’d wager the supernova went off before the earth even formed
in a so-called stellar nursery, where the shock wave of the explosion initiated the collapse not only of our own solar system, but probably many others. The black hole, if one formed, is still around, but has orbited the galaxy 20 times by now and could be anywhere and have merged with others. Its nebula would have disappated long ago. In other words, evidence would be very hard to identify now; we’re talking about events that happened 4.5 billion years ago.
This PROVES Nibiru! Oh, sorry.
