The Sun is getting brighter every year Within 3.5 billion years its brightness is expected to increase by 40% and its radius will be 256 times larger than it is today. Such a catastrophe leads to the complete disappearance of water from the surface of the Earth and ultimately destroys all forms of life. By then, conditions on our planet will be similar to those on Venus today #Sun @AstroMechanics 359 views02:51
