Is it a threat or a nature running errands? Let’s learn a Star’s lifecycle!
OR
Some fascinating astronomers discovered an explosion (science calls it nova) occurring at a nice looking constellation of Centaurus. A beautiful twinkling star named V1935 Centauri gone boom at September 2025. “What is going on here? Exploding stars??” Few people remain confused about it.

Is it a magician’s evil sorcery? Is our sun the next target? All these questions lay in the plot ‘bout how a star explodes, naturally or manually.
· Star’s Lifecycle: -
Death of a star doesn’t lay in
the deeds of any evil sorcerer. It’s actually science doing work in background.
When any star reaches it’s ‘End-of-life’, it just explodes, leaving a
residue like a white dwarf or a hungry-looking black hole. Before
all that, the star swells up, somewhat after when you have a delicious
occasional feast, into a red-giant/Red-supergiant.
A star swells into a Red-giant
if it’s an average star. The star swells into a Red-Supergiant if it’s
contained with big mass or weight. The average Red-Giant explodes into a
white dwarf, a teeny-tiny star that goes dim post-years, whilst the chunky Red-Supergiant
into a rather hungry black hole or a unstable neutron star.
If it much chunkier, a black hole is its inevitable fate, while the less chunky one into a neutron star.
· Lifespan of our Sun: -
Our Sun is an Average star,
which takes time to die that quickly. Phew! But Our Sun is already 4.6
billion years old, i.e. It’s halfway through its lifespan of 10 billion
years.
To say approximately how long it will last, Our Sun might continue living for more 5 billion years. Our Sun right now is more like a person already with a job, & is halfway through its life.
For now, we won’t have to worry
about our Sun exploding, causing wide spread chaos throughout our planet team. But
when it does pass its 5 billion years, it will swell up into a grandpa
red-giant & soon might eat up almost all the inner planets, possibly
including Earth!
Once after that, our Sun will live for more half a billion years & then explode into a white dwarf. Outer planets like Jupiter & Saturn might still remain with the dead sun.
For now, we won’t need to worry
about the sun exploding that soon, as we humans only live for a maximum of 100
years. Our sun is still good & shining bright, always waking us during the
dawn. So do your work, & thank the sun for giving us sunlight!
