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!
What else can I help you with?
What planet is aligned with earth?
Before anybody can touch that question, you have to explain what you mean by 'aligned'. Every planet in the solar system is on the same line from the sun that the Earth is on at least once a year. One or two of them do it more than once a year.
What powers a satellite?
solar energy from solar panels :) ;)
What is the galaxy of Venus'?
Venus is the 2nd Planet in Our Solar System. Our Solar System is in The Solar Neighborhood. The Solar Neighborhood is in The Orion Arm. The Orion Arm is on The Milky Way Galaxy.
What is the definition of a solar cooker?
Solar is a device which Run from sunlight
What type of solar phenomenon can produce seismic waves?
solar flares
How was the Solar neutrino problem solved?
The problem was that the Sun should output a lot more electron neutrinos then were measured. This meant that the model describing the interior of the Sun would be wrong, but it was working very well in predicting other things. It was finally solved when something called neutrino oscillation was discovered. It turned out that (this might be a bit technical) the interaction state of a neutrino was not equal to its mass or propagation state. In short, this meant that electron neutrino's could become muon or tau neutrino's after a while (and change back again after that). After this people began looking for muon and tau neutrinos coming from the Sun and together with the electron neutrino number they added up to the amount the Solar model predicted. The problem was thus solved; the Sun DOES output more electron neutrino's but some of these change into muon or tau neutrinos before they reach the Earth, and since we were initially only looking for electron neutrinos we missed some.
What is the dolar neutrino problem?
I presume you mean, "What WAS the Solar neutrino problem?"Our understanding of our Sun's core predicted a certain number of neutrinos would hit our Earth per second. Measurements of neutrinos from our Sun were substantially different from this number. The scientists who did the theories said the scientists doing the measurements were wrong; and vice versa -- an argument that went back and forth for forty years.We now know that neutrinos do decay, thus perfectly explaining the lack of neutrinos that are measured as coming from our Sun.The scientists who write the theories are busy trying to explain neutrino decay.
Are scientists trying hard to detect solar neutrino?
Yes but not at much high level
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.
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.
What is the smallest member of the solar system?
The smallest member of the Solar System is a dust grain such as a micro-meteoroid. Or if you want to get a lot smaller, then a hydrogen atom. Even smaller, a neutrino from the Sun.

Why Trying to explain why a solar eclipse occurs is an example of?
Shadows. All eclipses are shadows. A lunar eclipse is the shadow of the Earth on the Moon. A solar eclipse is a shadow of the Moon on the Earth.

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.
Explain earth 's position in the solar system and describe its neighbors?
explain earth's position in the solar system and describe its closest neighbors.
What is the mass of a neutron star?
Neutron stars range in mass from 1.35 Solar masses (2.69e+30 kg) to 2.40 Solar masses (4.16e+30 kg). Any smaller, and electrorepulsive forces will not allow the object to attain this stage (it would be a white dwarf instead), and any heavier, and the neutron star will collapse further into a black hole. This is called Schandraskar's limit a star must be at least 3 solar masses to be a candidate for a black hole however according to the Tolman, Oppenheimer, Volkov limits and star over 5 solar masses must become a black hole
