We are living on very busy planet and into era of science and technology. Everything revolves around life. Something which is even more important than our life is life of our planet Earth. And Earth life is directly related to the life of Sun.
According to latest research by NASA the sun is dying slowly because some extraordinary changes have been seen on Sun over past few decades. The scientists discovered that sun’s core is shrinking—an indication that it may be using up its hydrogen fuel at a faster rate than previously believed. Unfortunately, when the thermonuclear reactions at the core begin running out of hydrogen fuel, a star falls back on the next available element it has to burn: helium. Once that process starts, a star the size of our sun begins expanding and becomes a Red Giant.
Along with this the sun is also rapidly cooling and weakening to such a significant degree that it will—if the process continues unabated—eventually no longer shield the Earth from deadly cosmic rays. That’s because the Earth is usually protected by the sun’s magnetosphere, and as you’ve probably guessed, the magnetosphere’s shrinking too. According to scientists this cooling of sun has started since 1979.
Now from 2007 scientist has predicted that Sun has again started to become hot. If becoming cold is dangerous to earth then becoming too hot is also dangerous for earth. The reason for this is the observations of other stars with the Hubble Space Telescope, and several European Space agency telescopes, which confirmed that some stars like our sun suddenly begin exhibiting inexplicable behavior—and then, with little warning, they rapidly swell into Red Giants swallowing any nearby planets.
For months mounting fear has driven researchers to wring their hands over the approaching solar storms. Some have predicted devastating solar tsunamis that could wipe away our advanced technology, others voiced dire warnings that violent explosions on the surface of the sun could reach out to Earth, breach our magnetic field, and expose billions to high intensity UV-rays and other deadly forms of cancer-causing radiation. Even a small change in earth magnetic field can cause break down in all communications, electricity, nuclear plants and so on.
