End of the world: Why scientists fear sun will evolve to ENGULF Earth on THIS date

The sun currently sits in what is known as the main sequence, a band of stars in hydrostatic equilibrium – meaning it is resting at a constant point due to external forces such as gravity.

Louise Harra, Professor of Solar Physics at UCL Mullard Space Science Laboratory, revealed how it has been comfortably placed here for more than 4.5 billion years, but that will not last forever.

She told BBC Radio 4 listeners on a 2015 episode of “In Our Time” called “The sun” that it is “quite a boring star, really”.  

However, she added: “There is a lot of activity going on inside and you get a lot of dramatic explosions.”
