Scientists have detected neutrinos formed during a largely mysterious process in the Sun, in what they are hailing as a major breakthrough.

The discovery could help reveal the structure of our Sun and the elements within its core. But it could also allow us to better understand other phenomena throughout the universe, such as supernovae or the insides of distant stars.

The detection was made using the Borexino Collaboration, a vast particle physics experiment located in Italy and worked on by researchers from around the world. It aims to better understand the processes powering the Sun, as well as those in other stars.

An expert who was not involved in the research said that the new results “blast past a milestone in neutrino physics”.

“Measurements of these neutrinos have the potential to resolveuncertainties about the composition of thesolar core, and offer crucial insights into the formation of heavy stars," wrote Gabriel D Orebi Gann from the University of California, Berkeley, in an article accompanying the publication of the research in Nature.






“The Borexino Collaboration’s tremendous accomplishment moves us closer to a complete understanding of our Sun, and of the formation of massive stars, and is likely to define the goal in this field for years to come.”


Stars shine from the nuclear fusion of hydrogen into helium. That can happen in two ways: what is called the proton–proton or pp chain, which involves only hydrogen and helium, or the carbon–nitrogen–oxygen or CNO cycle, where the fusion is catalysed by carbon, nitrogen and oxygen.

In our own Sun, and other stars of a similar size, the pp chain accounts for some 99 per cent of the energy. Researchers have studied it extensively since the early 1970s, and the Borexino experiment has helped contribute to a comprehensive understanding of the processes that govern it.


But the CNO cycle – which represents a tiny but important minority of the energy production – has proven more mysterious. The small number of neutrinos that come from that mechanism mean that they are difficult to separate from background signals.

Now researchers say they have detected neutrinos coming from that process, however. Because the Borexino detector is sensitive and highly attuned so that it can block out background noise – as a result of recent breakthroughs that allow for the detector to stop the detector being contaminated – it was able to specifically pick up those neutrinos, which until now have remained mysterious.



It is the first ever time that researchers have been able to pick up those neutrinos – or direct evidence for the CNO cycle in any form at all. It is the first time that humanity has seen evidence of the mechanism that converts hydrogen into helium throughout the universe.

It also confirms theories about that cycle, including the fact that it accounts for only one per cent of the Sun’s energy.

Though that is a small proportion of the Sun’s power, the discovery could lead to large breakthroughs in the understanding of stars, the researchers say. The measurements can be used to understand how much carbon, nitrogen and oxygen might be found in stars such as our Sun, and how it might be structured.

What’s more, other, heavier stars are thought to rely on the CNO cycle much more than our own Sun, where that process is the dominant way of producing energy. The new findings could help show whether that is true and by what degree, allowing us to understand how other stars are powered too.

BECOS OF MY BIG BALLS









NONSENSE

God is the Source of Sun

iwaeda:
God is the Source of Sun

Hahahahahaha . In this 21st century...

I guess na God also dey make rain rain....

Sun must shine...

This research just for knowing how much oxygen , carbon , nitrogen found in stars such as sun .
This people sha !
They dont even think of if something strange happen

Righteousness89:
Our Scientist are becoming confused as the days go by!

God Almighty will be Laughing over this!!

No, it is the nature that is laughing at your ignorance level about cosmos

Until una near that sun, carry the particles come show me.
Make I use am manufacture bulbs.

Useless research

That’s where God take pass us as humans.


The Sun.

Scientists are wonderful. More grease to their elbow

iwaeda:
God is the Source of Sun

Maybe God set the mechanism? But please understand the science explained without blinding yourself with religion.

Righteousness89:
Dear Scientist! Give Honor to whom Honor is Due!
No man knows or has a hand in what powers these things..

It's Solely the Goodness, Creativity and Greatness of GOD ALMIGHTY

Shatap there!
Does your god or religion against knowledge?

Very correct

Righteousness89:
Dear Scientist! Give Honor to whom Honor is Due!
No man knows or has a hand in what powers the Sun, Moon, stars etc
They are God's Gift to Humanity,,

It's Solely the Goodness, Creativity and Greatness of GOD ALMIGHTY

Can't you use your reasoning for once?

helinues:

Hahahahahaha . In this 21st century...
I guess na God also dey make rain rain....

God is the source of rain

SCIENTISTS ARE MAD

helinues:


Hahahahahaha . In this 21st century...

I guess na God also dey make rain rain....

NA NOW I KNOW WHY YOU NOR DEY REASON WELL . YOU NEED GOD IN YOUR LIFE BRUH

WHAT IS WRONG WITH WHAT HE JUST SAID
