Scientists have for the
first time detected the solar neutrino particles forged in the sun’s heart that
are eventually emitted into the galaxy as light, according to RT monitored
reports.
More than 100 international scientists from the University of
Massachusetts Amherst worked together using the Borexino detector in Italy to
make the discovery, which provides humans with a peak into the process of
nuclear fusion that is responsible for bathing the Earth with light. The
findings were first reported in the latest issue of the Nature journal.
Although it only takes
eight minutes for light from the sun to hit Earth, there is a substantially
longer process that takes place before that can happen. After the solar
neutrinos are formed in the sun’s core, another 100,000 years must pass before
they make their way to the star’s surface and shoot out at the speed of light.
“The first step in the
dominant fusion process in the sun starts when two protons in its core fuse
into a deuteron, creating a [proton-proton] neutrino,” wrote Nola Redd at Space.com. “Other
neutrinos are created in subsequent steps of the process, several of which have
been detected, but the first-step neutrinos remained elusive.”
Now that these neutrinos
have been detected, though, scientists are hoping to learn even more about the
sun’s energy-forming processes.
"[The neutrinos] are
the most direct confirmation that nuclear fusion is the source of energy [for
the sun],"
said Wick Haxton of University of California, Berkeley, to the website.
Once the particles shoot
out of the sun, they make their way to the Earth extremely quickly, showering
every square inch of the planet’s surface with up to 420 billion every second.
“By comparing the two
different types of solar energy radiated, as neutrinos and as surface light, we
obtain experimental information about the sun's thermodynamic equilibrium over
about a 100,000-year timescale,” said university scientist, and international
team member, Dr. Andrea Pocar, to the Daily Mail.
“If the eyes are the mirror
of the soul, with these neutrinos, we are looking not just at its face, but
directly into its core. We have glimpsed the sun's soul.”
