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.
