How can neutrino oscillation explain the solar neutrino problem?
The solar neutrino problem relates to the discrepancy between the proportions of the different flavours of neutrinos emitted by the sun in the theoretical model as opposed to experimental measurements. Whilst the sun primarily emitts electron neutrinos, neutrino observatories such as SNO+ detected neutrinos in roughly equal proportions of the three flavours; furthermore the quantity of electron neutrinos detected was less than the theoretically predicted value. Both of these can be explained by neutrino oscillation - in which the neutrinos alter their mass to change their flavour (ie. an electron neutrinos gain mass to change to a muon neutrino). This would also explain the relative lack of electron neutrinos, thus solving the solar neutrino problem!
Are neutrinos mediated by electromagnetic interaction?
No, neutrinos are mediated by weak interactions, Photons are mediated by electromagnetic interactions.
What part of the Sun do neutrinos originate?
The core.
Are neutrinos their own antiparticles?
Answer 1There are three different types of neutrinos. Each one is associated with its own antiparticle, but is not an antiparticle itself. Answer 2Particle and antiparticle are distinguished by their charges. The positron, for example, the antiparticle of the negatively charged electron, is positively charged. The neutrino, on the other hand, is electrically neutral-the prerequisite for the ability of being its own antiparticle. However, I assume that the antiparticles of neutrinos are neutrinos with opposite spinning direction.
Is there any particles whose velocity is greater than photon particles?
Possibly neutrinos are . . . scientists right now are thinking that neutrinos travel faster than light (photons)
Do solar neutrino carry energy?
Yes, solar neutrinos do carry energy. Neutrinos are extremely light, neutral particles that are produced in nuclear reactions within the Sun's core. The energy carried by solar neutrinos can affect processes such as nuclear reactions on Earth.
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.
Are scientists trying hard to detect solar neutrino?
Yes but not at much high level

At the solar neutrino observatory what is used to capture neutrinos?
In the solar neutrino observatory, neutrinos are captured using tanks filled with a type of heavy water called deuterium oxide. Neutrinos interact with the deuterium nuclei in the water, producing a faint flash of light that can be detected by sensitive instruments.
Explanation of missing solar neutrinos?
Neutrinos are incredibly hard to detect so the "absence" of neutrinos doesn't mean they are not there. It was long thought that neutrinos did not decay. We now know they do so. Thus, the lower than expected number of neutrinos detected coming from the Sun has been fully explained. It took four decades but the problem is now fully resolved.
What particle do you detect coming directly from the solar interior?
Neutrinos are the particles that are detected coming directly from the solar interior. These particles are produced by nuclear reactions in the core of the Sun and are able to pass through vast amounts of matter, making them excellent indicators of solar activity.
How do measurements of neutrinos from the sun pose a problem for modern astronomy?
At present, no problems. 15 years ago, scientists had no explanation for the small number of solar neutrinos detected at our Earth. Either we didn't understand neutrino formation in our Sun, our detectors were wrong, or neutrinos had the capacity to decay. The latter seemed to be the least likely possibility, so scientists argued for many years which of the first two was correct. In 1998 it was discovered that neutrinos do, indeed, decay into other neutrinos. The reason we weren't seeing as many neutrinos as we expected was because the ones we were expecting to see had decayed into other types. So the solar neutrino problem is no longer a problem.
What are the different flavors of neutrinos and how do they differ from each other?
Neutrinos come in three flavors: electron neutrinos, muon neutrinos, and tau neutrinos. These flavors are distinguished by the type of charged lepton they are associated with - electron, muon, or tau. Neutrinos can change between these flavors through a process called neutrino oscillation, which is a unique property of neutrinos.
What are neutrinos-?
Neutrinos are subatomic particles, which exist in three "flavours" - the electron, muon and tao neutrino (listed in order of increasing ass); each of these also has a respective antiparticle. Most of the neutrinos incident on the Earth are "Solar Neutrinos" (neaning that they are emitted by the sun. The neutrinos oscillate between the different "flavours", which are determined by their respective masses, and are extremely unreactive - more than 50 trillion neutrinos go the human body every second! As the masses of the neutrinos are very minimal - virtually zero - neutrinos travel at near-light speed.There have been several experiments dedicated to the detection of neutrinos, the most notable being T2K and SNO amongst others; SNO is currently being re-activated with enhanced detection prospects through the use of an organic scintillating fluid, as is now named SNO+.
Can neutrinos change into other types of neutrinos?
Yes; the scienific terminology for this phenomenon is "neutrino oscillation". Neutrinos exist in three different flavours - electron, muon and tao neutrinos, listed in order of increasing mass (each also has an antiparticle). Although it is not know why this is the case, it was originally discovered that neutrinos oscillate when examining the neutrinos emitted by the sun; although primarily electron neutrinos are emitted as a result of the fusion process within the sun, the quantities of the different flavours of neutrinos detected on Earth from the sun are in roughly equal proportions.
What are the uses of neutrino?
Neutrinos are similar to electrons, but are different, in that neutrinos do not carry electric charges.
