yes folks i do understand and kniow that this system that is in question is not the same situation as our solar system, But the fact remains our sun will die in a red giant then back burning the complete solar system,

Answer 1

First of all, yes our sun will die eventually, but not for billions of years as scientists say.

Second, the article you're asking about deals with a binary system of a white dwarf and a red giant, in which the red giant's gas is collecting on the white dwarf's surface, causing explosions periodically. This is an entirely different situation than our own solar system, so you can't really compare the two.

Answer 2

That would be a flash known as a nova. That could harm no one.

Also the sun will not go nova OR supernova.

The Sun, in 4.5 billion years supposedly, WILL start to swell. It will get bigger, and en-gulp Mercury and Venus. The atmosphere will evaporate, water will melt, and life will be gone. The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf. Then In a few billion years, cool down to a black dwarf.

The reason the sun expands, In case you want to know, Is because of its fuel supply. The energy from the sun comes from nuclear fusion of Helium. When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell. The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planetary nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf. Eventually, it will cool into a black dwarf (not to get mixed up with black hole) and die.

It will only reach up to about Mars at max, so the rest of the solar system is safe. However, earth ius doomed...

Answer 3

I didn't click on the link, but our Helio Observatory - or soimething like that - you know, the one that monitors solar flares, it would show a pattern, and we would know about it long before it began to happen.
that's why we are building the space station.

Answer 4

YES this could also happen to our SUN but this million years our sun was good friend and faithful to us. thank goodness if it did explode we won't be here CAN'T EVEN IMAGINE THAT WOW HOW A GOOD AND TRUSTWORTHY FRIEND IS OUR SUN SO BEAUTIFUL DURING DAWN AND DURING DUSK.
