It seems that humans are the only living being in the Universe. Because phosphorus which is one of the chemical elements of life is rare outside the solar system. Well, this could be bad news for those who are searching for alien life in the universe. As per the new study conducted by Jane Greaves and Phil Cigan, astronomers at Cardiff University informed that phosphorus is abundant on Earth, but in space it is rare. As it, an essential element for like, its unavailability in space indicates that life is also rare in space.

The origin and development of life are quite complicated to understand because it depends upon various condition and elements like phosphorus. So, if these elements go rare, then the existence of life will be very difficult. For instance, phosphorus, which is very common on Earth where life sustains but its availability in space is totally opposite. As per the researchers, phosphorus which can accelerate organism development chemical reaction was brought by meteorites to Earth. It is an important element in the compound adenosine triphosphate or ATP. This stores energy and transfer that stored energy throughout the body.

Greaves stated, “Phosphorus is one of just six chemical elements on which Earth organisms depend, and it is crucial to the compound Adenosine Triphosphate (ATP).” When the researchers examined the cosmic origin of phosphorus, they discovered some interesting facts. In the new study, they examined data taken by the William Herschel Telescope situated in the Canary Islands. The examined the infrared light developed by iron and phosphorus in a supernova called the Crab Nebula which is situated at around 6,500 light years away in Taurus constellation.  Crab Nebula was developed from a supernova explosion which was detected by Chines astronomers in 1054 CE. Then when they compared the findings with the data from the Cassiopeia A, they came to know that the Crab Nebula has less amount of phosphorus.

Informing more on it, Cigan stated, “This is only the second such study of phosphorus that has been made.” He further added the two-supernova explosion are different from each other and the reason is Cassiopeia A develops from a rare supermassive star explosion.  However, for now, the researchers are examining more on it to understand the relationship between supernova and phosphorus. The new findings will be presented at the European Week of Astronomy.
