Science n space mysterious, learning about ghostly neutrinos
#1
Neutrinos - These tiny, high-energy cosmic particles are often referred to as "ghostly" because they are extremely volatile, or vaporous, particles that can pass through any kind of matter without changing.

Said Peter Gorham, professor of physics at the University of Hawai'i at Mānoa. "The universe is chock full of them. A billion of them go through our noses every second and we don't even feel it."

U.S. Navy recently admitted that, indeed, strangely behaving objects caught on video by jet pilots are genuine head-scratchers. Their eyewitness accounts not only from pilots but from radar operators and technicians, too.

In August, the Navy established an Unidentified Aerial Phenomena (UAP) Task Force to investigate the nature and origin of these odd sightings and determine if they could potentially pose a threat.

Recently observed UAPs purportedly have accelerations that range from almost 100 Gs to thousands of Gs — far higher than a human pilot could survive.

There's no air disturbance visible. Don't produce sonic booms and other oddities have captured the attention of "I told you so, they're here" UFO believers.

The first detection of neutrinos produced by Sun’s secondary solar-fusion cycle paves the way for a detailed understanding of the Sun structure. A milestone in neutrino physics.

They have detected solar neutrinos produced by a cycle of nuclear-fusion reactions known as the carbon–nitrogen–oxygen (CNO) cycle.

Measurements of these neutrinos have the potential to resolve uncertainties on composition of the solar core, and offer crucial insights into the formation of heavy stars.

Apparently missing β-decay, a process in which electrons are emitted from atomic nucleus. Presence of a massless particle energy from the decay would explain why the spectrum of emitted electron energies is continuous.

Neutrinos experimental produced CNO fusion cycle in the Sun. Fusion reactions in the Sun produce an astonishing number of neutrinos: roughly 100 billion solar neutrinos that passed through each of your thumbnails every second. B'cos they are barely deterred even when they have to pass through the entire body of the Earth:

Neutrinos are both challenging offering insights into other-wise unreachable regions of the Universe, such as distant supernovae or the interiors of stars.

Energy produced in Sun core in the form of photons takes tens of thousands of years to escape, but a solar neutrino can escape the Sun n reach Earth in just 8-minutes. Surprised

Sun is powered by fusion reactions in its core intense heat of this highly pressurized environment, n protons fuse together to form helium.

A decades-long experiments to resolve ‘solar neutrino by Sudbury Neutrino Observatory in Ontario, Canada, explained the deficit:, neutrinos changing flavour between their production and detection.

Borexino experiment @Gran Sasso National Lab. Italy followed up with a full spectral analysis of neutrinos.

Borexino reports another achievement. Resulted a huge leap forward, offering the chance to resolve the mystery of the Sun’s core. In astrophysics. The metallicity n opacity of Sun affect speed of sound waves propagating through its volume. For decades, helio-seismological measured were in agreement with SSM predictions for speed of sound in the Sun, giving confidence in this model.

Chief obstacles?. Making measurements are the low energy and flux of neutrinos, and the difficulty of separating neutrino signal.

A step closer to Sun’s secrets n secrets of the galaxies.

Neutrinos from a long-theorized nuclear fusion reaction in the sun have been definitively observed, confirming the process that powers most stars.

Neutrinos discovered in 1956 come in 3 flavors (or types) and have mysterious characteristics. They have puzzlingly low masses compared to other elementary particles, n are able to oscillate, or change from one type of neutrino to another.

A Standard Model, best description as fundamental particles that make up our universe, predicted neutrinos would have no mass. However, when oscillation experiments. Neutrinos do have tiny masses. It could there for are the only basic fundamental particles that gain their mass from a source other than the Standard Model Higgs field.

Neutrinos could have other strange 4th properties as well n could turn out to be identical to anti-neutrinos, their anti-matter counterparts.

They could be related to massive particles that theorists think might have greatly influenced the formation of our universe.

In 1999, the lab broke new ground on its first long-baseline neutrino experiment, MINOS, which studied the oscillation of muon neutrinos to tau neutrinos into other flavors. @Fermilab, DONUT experiment made it first ever direct observation of a tau neutrino in 2000.

Neutrinos are mysterious particles that could hold the key to answering many questions about our universe.

How much does a neutrino weigh?

we still don’t really know the absolute mass of the neutrino.

Only to know that the three known types of neutrinos have different masses and that the sum of all three of those types is still less than one millionth the mass of an electron.

Particles are often measured (weighed) in units called electronvolts. For comparison, one electron has a mass of 511,000 electronvolts. Put it another way, a neutrino is 10 billion, billion, billion times smaller than a grain of sand.

Neutrinos fill the whole universe, n galaxies with about 10 million of them per cubic foot, and most of them zip straight through Earth, our body and through particle detectors, without leaving a trace. Because they almost never interact with matter, only massive and sophisticated experiments can catch and measure the properties of neutrinos.

Why Neutrinos are Important to us?.

Riga Technical University.

A team of scientists is working on technology that could one day stop asteroids from smashing into Earth.

The high-precision timers being built by hand in the lab of Latvian start-up Eventech are currently being used to track satellites.

This year, the company won a Euro Space Agency (ESA) contract to develop timers that will study the possibility of re-directing an asteroid before it comes too close to our planet for comfort.
