Scientists have finally gathered direct evidence of how the universe discourages its heavier elements, a process that has been a puzzle for more than half a century.
A team from the Flatron Institute in New York City calculated those giant torches emitted by Magnet – Very magnetic types of collapsed stars known as Neutron stars It can be the long -awaited cosmic formula that creates heavy universe elements. It can only produce one of these giant torches of gold, platinum and uranium.
“It is amazing to believe that some heavy elements around us, such as precious metals in our phones and computers, said” It is amazing to believe that some heavy elements around us, such as precious metals in our phones and computers, said, “It is amazing to believe that some heavy elements around us, such as precious metals in our phones and computers, said. statement. “Magnetic giant torches can be the solution to a problem we faced as there are more heavy elements in small galaxies more than it can be created from the collision of the neutron stars alone.”
Lighter elements such as hydrogen, cardium and lehium were falsified in the big explosion, while the heavier elements were formed through nuclear fusion in the stars during the life of the stars – or in the aftermath of their explosive death. But how the elements rich in neutron remained heavier than iron making an open question.
It is believed that these elements are formed through a series of nuclear reactions known as the process of capturing the fast neutron, or R, which was a long theory in the maximum conditions such as those present. Supernovas or Integration of neutron stars. In 2017, astronomers confirmed the first time process during the noticeable integration of two neutron stars.
However, such collisions are very rare so that they cannot calculate the abundance of heavy elements in the universe and the integration of neutron stars very late in the history of the universe to explain the oldest golden elements and other heavy elements. But the extreme neutron flares that can make these elements is much older. “The interesting thing about these giant torches is that it can occur early in the history of the galaxy,” Patel added.
To study these operations, New York City scientists have turned into the magnet, who Magnetic fields Trillion times stronger than the ground. These stars sometimes produce “Mashael” – bursts of energy caused by the sudden launch of magnetic energy, which are usually caused by rearrangement or decomposition of their magnetic fields.
According to the team, the giant glow in Magnetar can create the appropriate conditions for operations elements R to form, resulting in a very unstable radiant nuclei that decomposes into stable heavy elements such as gold.
Dishing, the New York City team managed to link their accounts b Mysterious note Made in 2004 a bright flash of light from Magnetar SGR 1806-20. Initially, the event was not unusual – until the researchers realized that the total Flare energy was almost more than a thousand times than those that the typical bursts emerge.
“This event has been forgotten over the years.” “But we quickly realized that our model was suitable for him.”
“I was not thinking about anything else for the next week or two weeks,” Patel He said in a NASA statement. “It was the only thing in my mind.”
By combining SGR notes 1806-20 2004, Metzger, Patel, and their colleagues estimated that this event has produced about 2 billion billion (you read this right) of heavy elements – almost a block of mass Mars Or 27 satellites! While such torches can represent about 10 % of all heavy elements in our galaxy, researchers note that the remaining 90 % assets are still unconfirmed.
“We cannot exclude that there may be third or fourth sites that we have not yet seen,” Metzger said.

They eager to push their discovery further, the team plans to find more magnetic flares using the Compton and NASA mission, which is scheduled to be launched in 2027 – a task that can reveal more secrets about the cosmic assets of golden elements and other heavy elements.
“It is a somewhat essential question in terms of the origin of the complex issue in the universe,” Patel said. “It is a fun puzzle that has not already been solved.”
The team’s research was published in Astronomical physical magazine messages.
