Ever thought how the most significant start of the solar system, Sun will come to an end, and in the manner, destroy Earth and the rest of the planets in the solar system? Based on investigations of an enormous red star outside of our solar system, scientists have noticed giant bubbles on its surface, indicating that it is in the process of dying, Times Now says.
Images are taken from the Large Telescope in the European Space Observatory unveil the enormous bubbles on the exterior of the ‘Gruise’ star that sits away approximately 500 light years in the Grus constellations.
Stars are enormous masses of hydrogen, and when they burn through their resources, they contract and become remarkably hot. The outer layer of the star then extends when it comes in contact with the burning central core, describing why stars grow as they age into red giants. The expansion process continues resulting in it becoming hundreds of time its original size, but with a thinner density.
When the ageing process kicks in, the ‘convection cells’ on the surface of a star are changed. These are necessarily stores of liquid held in place by the movement of heat. By definition of convection, as the hot fluid moves towards the centre of each spot, cooling fluid moves down from the edges, thus suspending the liquid in bubbles on the surface.
With the sun emitting its outer layers over tens of thousands of years, creating a nebula, the liquid on Earth, especially in the form of oceans will boil, sealing the atmosphere with nitrogen and carbon dioxide. As a consequence, life on Earth will cease to exist even before the solar explosion destroys the entire solar system.
However, investigators estimate that the Earth has around five billion years before the Sun turns into a red giant.
