Evidence emerged that the sun's core is shrinking—an indication that it
may be using up it's 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.
No, it won't explode as a nova or
supernova, it doesn't have the mass. It will just swell up and up and
vaporize Mercury, Venus, Earth and Mars.
Second, astrophysicists discovered an unknown type of solar particle was mutating matter on Earth. What is this strange new particle? What are its properties? Why is the sun suddenly spitting them out?
No one has a clue.
