What little we still know about the sun!
The sun is the most important factor affecting climate on earth, not CO2! The sun and its output is not a constant as we are supposed to believe!
Global Warming is a hoax and Climate Change a religion!
"Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt (TeV), at least five times more energetic than previously known. ...
A few decades later, these gamma rays were eventually detected by NASA’s Fermi Gamma-ray Space Telescope in 2011. With more and more observations over the years since, Fermi found that the Sun was producing around seven times more gamma rays than had been predicted. Their energies were detected at up to 200 giga electron volts (GeV), which is the upper limit that Fermi can pick up. So for the new study, scientists used a different instrument that’s sensitive beyond that limit. ... Exactly how the Sun produces them remains a mystery ..."
"... In the 1990s, scientists predicted that the sun could produce gamma rays when high-energy cosmic rays — particles accelerated by a cosmic powerhouse like a black hole or supernova — smash into protons in the sun. But, based on what was known about cosmic rays and the sun, the researchers also hypothesized it would be rare to see these gamma rays reach Earth.
At the time, though, there wasn’t an instrument capable of detecting such high-energy gamma rays and there wouldn’t be for a while. The first observation of gamma rays with energies of more than a billion electron volts came from NASA’s Fermi Gamma-ray Space Telescope in 2011. ..."
From the abstract:
"We report the first detection of a TeV γ-ray flux from the solar disk (6.3σ), based on 6.1 years of data from the High Altitude Water Cherenkov (HAWC) observatory. The 0.5–2.6 TeV spectrum is well fit by a power law, dN/dE=A(E/1TeV)−γ, with A=(1.6±0.3)×10−12TeV−1cm−2s−1 and γ=3.62±0.14. The flux shows a strong indication of anticorrelation with solar activity. These results extend the bright, hard GeV emission from the disk observed with Fermi-LAT, seemingly due to hadronic Galactic cosmic rays showering on nuclei in the solar atmosphere. However, current theoretical models are unable to explain the details of how solar magnetic fields shape these interactions. HAWC’s TeV detection thus deepens the mysteries of the solar-disk emission."
