Latest Neutrino Stories
The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole.
Astrophysicists believe that about 80 percent of the substance of our universe is made up of mysterious “dark matter” that can’t be perceived by human senses or scientific instruments.
Thanks to one of the most sensitive neutrino detectors on Earth, physicists have for the first time confirmed the existence of low-energy neutrinos created by the “keystone” proton-proton fusion process taking place in the core of the sun.
The PandaX experiment of China, which is located in the deepest underground laboratory, has released its technical design report recently.
What do you get when you combine polarized radiation with Einstein's theory of general relativity? According to a group of astrophysicists at UC San Diego, you just might get more accurate estimates for the mass of ghostly subatomic particles known as neutrinos.
Physicist Richard Schnee hopes to find traces of dark matter by studying particles with low masses and interaction rates, some of which have never been probed before
An astrophysicist has created a new three-dimensional model that provides new insight into the death throes of supernovae. The model is the first to represent the start of a supernova collapse in 3D.
Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/
Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos.
Scientists at a massive underground particle detector in Antarctica called the IceCube South Pole Neutrino Observatory have detected high-energy neutrinos, ideal for the future of "extreme astronomy" because they can be used to detect the sources of cosmic rays and provide information about our universe's most violent and least-understood phenomena.
The IceCube Neutrino Observatory is a neutrino telescope that is currently being built at the Amundsen-Scott South Pole Station. IceCube is being constructed in deep Antarctic ice by deploying thousands of PMTs (photomultiplier tubes) at depths of 4750 to 8000 feet. These spherical optical sensors are deployed on strings of sixty modules each, into holes melted by hot water drilling. Since 2005, 59 strings have been deployed and installation is expected to be complete by 2011. The strings are...
WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....
Sudbury Neutrino Observatory -- The Sudbury Neutrino Observatory (SNO) is taking data that has provided revolutionary insight into the properties of neutrinos and the core of the sun. The detector, shown in the artist's conception below, was built 6800 feet under ground, in INCO's Creighton mine near Sudbury, Ontario. SNO is a heavy-water Cherenkov detector that is designed to detect neutrinos produced by fusion reactions in the sun. It uses 1000 tonnes of heavy water, on loan from...
