The universe 'scarce' phosphorus, and aliens are not as much as we expected

Many scientific studies have shown favorable conditions for life to appear, exist, and grow in a certain planet. However, we almost never verify the existence of alien creatures. Why?

According to Independent, a new study shows that the universe is a "lack of" phosphorus - a substance known for its vital role in life. It helps us store and transmit energy throughout the body, and form DNA bases.

The study also suggests that we have enough phosphorus on Earth because our planet is close enough to one (some types of stellar explosions that make very bright objects mainly composed of plasma flaring in A short time, apparent star level increased dramatically billions of times, then gradually decreased in a few weeks or months - according to Wikipedia. Phosphorus is formed when stars explode at the end of their life cycle. However, not all supernovae are in the right conditions to produce such phosphorus.

Earth seems to be a lucky planet, because it is close enough to a supernova that can produce phosphorus.

Astronomer Jane Greaves, from Cardiff University, said: "The way to bring phosphorus to a" newborn "planet seems quite precarious. We think there is only a bit of phosphorus-containing minerals to be taken. to Earth - probably in meteorites - and that's enough to react & participate in the creation of proto biological molecules ".

"If phosphorus originates from supernovae , and then travels through space in meteorites, I wonder if a small planet can identify itself with phosphorus deficiency based on its location. Is it already born close to an unqualified supernova to produce phosphorus? In that case, life will be hard to start without phosphorus, and another world. it will be difficult to exist without the same conditions as our Earth " - he added.

The evidence of this study stems from observations of two famous supernova remnants - Cassiopeia A (Heavenly Constellation) and the Crab Nebula (a stellar wind nebula in the constellation Taurus, at the same time, the remains of supernova Thien Quan guest SN 1054). The team used the British William Herschel telescope in La Palma, the Canary Islands to search for traces of phosphorus and iron from the Crab Nebula - the result of a supernova explosion 6,500 light years ago. shining in the constellation Taurus. And a previous study found phosphorus from the constellation of astronomy, 11,000 light-years away.

Comparing results from two observations shows that the amount of phosphorus from is less than the amount of phosphorus from Cas A. This is a surprising result.

Dr. Phil Cigan - another astronomer in Cardiff, said: "The two explosions seemed very different, perhaps because Cas A was the result of an explosion from a rare superstar".

The findings are presented at the Astronomy Week and European Space in Liverpool. Scientists are planning to continue searching to find remnants of the supernova that lack phosphorus.
