Neutrino Astronomy

study of stars by means of their emission of neutrinos, fundamental particles that result from nuclear reactions and are emitted by stars along with light.
Neutrino oscillation is a quantum mechanical phenomenon predicted by Bruno Pontecorvo whereby a neutrino created with a specific lepton flavor (electron, muon or tau) can later be measured to have a different flavor.
Neutrinos
The neutrino is an elementary particle. It has fractional spin () and is therefore a fermion.

History
A neutrino cloud is a spatial anomaly composed of neutrinos, that generates an electromagnetic field. It is normally undetectable to sensors.

Neutrino :
The neutrino is a type of fundamental particle with no electric charge, a very small mass, and one-half unit of spin. Neutrinos belong to the family of particles called leptons, which are not subject to the strong nuclear force.
I have heard that neutrinos are responsible for a large amount of energy transfer out of stellar cores. I have also heard that neutrinos sometimes "carry" photons with them. How does this phenomena occur? I have a B.S.
There are a variety of ways to detect neutrino oscillation. In general, you have to get a look at a population of neutrinos at one point in the population's life cycle, and then again at a later point.

Neutrinos are particles that are extremely hard to detect because they interact very weakly with other matter. They may pass through the entire planet losing far less intensity than light passing through a window.
Neutrino
(a) An electrically neutral, very weakly interacting particle, with a rest energy which is either zero or very small.

Neutrino astronomers are forced to use such a roundabout technique because neutrinos are impossible to capture by run-of-the-mill telescopes. To build AMANDA, they are lowering its strings of detectors into holes drilled using hot water.
Neutrino
A neutral, weakly interacting elementary particle having a very tiny mass. Stars like the Sun produce more than 200 trillion trillion trillion neutrinos every second.

Neutrino: Any of three species of very weakly-interacting lepton with an extremely small, possibly zero, mass. Electron neutrinos are generated in the interior of the Sun (and other stars).
The neutrinos are neutral and have extremely low rest masses. They essentially do not interact with normal matter and so travel straight out from the core and escape from the star at almost the speed of light.

Looking at neutrinos helps us to figure out what the Sun is like, but other stars are so far away that it is nearly impossible for us to look for their neutrinos. How can astronomers figure out what is going on inside all of the other stars out there?
The Missing Neutrinos
The Sun should produce more than twice as many neutrinos than are observed. These ghostly subatomic particles are released by nuclear reactions in the Sun's core. They then pass directly through the Sun and out into space.

Once the core of the star has completely burned to iron, energy production stops and the core rapidly collapses, squeezing electrons and protons together to form neutrons and neutrinos.
01% of the energy is in the form of light and most of the remainder is in the form of neutrinos.
The conversion creates a deuterium (heavy hydrogen) nucleus as well as a tiny particle called a "neutrino." Detection of neutrinos on Earth allow us to "see" directly into the solar center.

The fusion reaction within the Sun also produces neutrinos which are a strange sort of particle without any mass so they can pass through almost any solid object.

Other scientists believe that dark matter may be composed of strange particles which were created in the very early Universe. Such particles may include axions, weakly interacting massive particles (called WIMPs), or neutrinos.
