The Gamma rays produced by fusion takes thousands of years to reach the surface of Sun. But neutrinos travel at the speed of light and reach us. So the light is telling us about the fusion which took place millions of years back. But the neutrinos tells us the current status.

Why are neutrinos important for studying the sun?
In the sun, 4 hydrogens are being fused into Helium by means of the proton-proton chain. Neutrinos are important because they allow scientists to peek into the interior of the sun and learn about the processes there.
What can neutrinos tell us about nuclear reactions in the sun?
Detection of particles produced by the Sun’s core supports long-held theory about how our star is powered. By catching neutrinos emanating from the Sun’s core, physicists have filled in the last missing detail of how nuclear fusion powers the star.
What information can we obtain by studying neutrinos from the sun?
Studying neutrinos is thought to be the best way to obtain direct information about the center of the sun, which is otherwise largely a mystery. Neutrinos can also give us information about supernovas, the creation of the universe and much more.
Why are neutrinos so important?
Neutrinos play a role in many fundamental aspects of our lives; they are produced in nuclear fusion processes that power the sun and stars, they are produced in radioactive decays that provide a source of heat inside our planet, and they are produced in nuclear reactors.
Why is it that neutrinos can tell us about conditions at the core of the sun hint how are they produced and what happens then?)?
Because they travel so fast and interact so rarely with matter, neutrinos pass from the core of the Sun to the surface in only two seconds. If you could detect them, the neutrinos would tell you about the conditions in the Sun’s core as it was only 8.5 minutes ago (much more current information than the photons!).
What do neutrinos makeup?
Fermions in general are the building blocks of matter. Baryons are made up of quarks, and there are six (6) types of quarks resulting in about one-hundred twenty 120 baryons. Neutrinos however fall into a category called leptons. Leptons are also fermions, and together with quarks make up matter.
How do neutrinos affect us?
Neutrinos don’t really affect the everyday lives of most humans: they don’t make up atoms (like electrons, protons and neutrons), and they don’t play a crucial role in objects their mass (like the Higgs boson). “However, the neutrino does have a tiny probability to interact, and this probability increases with energy.”
What is a neutrino and why are astronomers so interested in detecting neutrinos from the Sun?
What is a neutrino, and why are astronomers so interested in detecting neutrinos from the sun? Neutrinos are “ghost” particles that are released in the thermonuclear reactions in the Sun. They are “ghost” particles in that they are extremely difficult (but not impossible) to detect.
Why are neutrinos so difficult to detect?
Why are neutrinos so hard to detect? Neutrinos are very hard to detect because they have no electric charge. But when a neutrino passes through matter, if it hits something dead-on, it will create electrically charged particles. And those can be detected.
What part of the Sun do astronomers learn about by studying solar neutrinos?
Neutrinos from the Sun call tell us about what is happening in the solar interior. A recent experiment has shown that solar models do predict accurately the number of electron neutrinos produced by nuclear reactions in the core of the Sun.
What do we know about neutrinos?
Neutrinos are teeny, tiny, nearly massless particles that travel at near lightspeeds. Born from violent astrophysical events like exploding stars and gamma ray bursts, they are fantastically abundant in the universe, and can move as easily through lead as we move through air.
What is neutrino hypothesis?
The neutrino was postulated first by Wolfgang Pauli in 1930 to explain how beta decay could conserve energy, momentum, and angular momentum (spin).
