Sun exploded in our solar system

the Sun exploded that

star at the center of our solar system

that super hot ball of plasma that gives

us heat and energy and amazing

complexions well it's a ticking time

bomb the Sun is about 10 billion years

old but it's only expected to last about

another 5 billion years after that the

Sun will expand becoming a red giant

then it will shrink to become a white

dwarf a dying star cooling for the next

several billion years of course we'll

all be long gone before any of that

happens but still can you imagine what

it would be like to watch the Sun blow

up before your very eyes with a name

like supernova you'd think that a solar

explosion would be the most magnificent

fireworks show the world has ever seen

but in reality you likely wouldn't see

anything the Sun is 150 million

kilometres away from Earth and it takes

8 minutes for light from the Sun to

reach us and while that may seem super

far away in supernovae terms we don't

stand a chance for earth to be

completely safe from a supernova we'd

need to be at least 50 to 100 light

years away but the good news is that if

the Sun were to explode tomorrow the

resulting shock wave wouldn't be strong

enough to destroy the whole earth only

the side facing the Sun would boil

by instantly the lucky other half would

experience a rise in temperature that

would be 15 times hotter than the sun's

current surface temperature and

permanent darkness and without the sun's

mass keeping us in orbit earth would

likely start floating off into space

while its remaining inhabitants

desperately struggle to stay alive there

is a chance that our planet could lock

into orbit around another star that

might provide the same light and heat as

our Sun but by the time that happened

we'd all be long gone if we knew in

advance the day that the Sun would

explode then we could buy ourselves as

many as 1000 years of time provided we

had the resources to sustain ourselves

for that long and we could just a few

metres below the ground you walk on the

earth is maintaining a temperature of

about 17 degrees so if we had enough

time to prepare civilization could

continue to live by moving underground

into a huge network of fortified bunkers

within a week after the explosion the

surface temperature on earth would drop

to minus 18 degrees within a year

temperatures would plummet to about

minus 73 degrees at this point the

oceans would begin to freeze from the

top down within 1,000 years Earth's

atmosphere would freeze and collapse

leaving anything left on the surface

exposed to cosmic radiation and meteor

impacts hopefully by that point we'd

have found ourselves a new home the good

news is that if the Sun were to explode

and it will eventually happen it

wouldn't happen overnight when the Sun

does die it will be a long slow arduous

process taking place over billions of

years the Sun will get hotter and

brighter and it will start to expand

during this process it will lose its

outer layers to the cosmos leading to

the creation of other stars and planets

in the same way that the violet burst of

the Big Bang created Earth who knows

maybe new life could form can you

imagine a method earth a new humanoid

species it's hard to predict how our

galaxy might look billions of years from

now and it's especially hard to imagine

our solar system without the great

golden anchor that keeps us all together

but one day in the very very distant

future the Sun will expand and then it

will shrink maybe leaving room for a new

start to take its place and if by some

miracle humanity still exists at that

point where might we be living can you

imagine your descendants being born on a

space station
