Planet-eating stars hint at Earth’s ultimate fate
Introduction: A cosmic warning from starving stars From time to time, astronomers observe a dramatic finale in stellar life cycles: stars that grow so large and fierce they can engulf nearby worlds. While these events are distant, they offer a window into the ultimate fate that may await our own planet. The idea that a…

Planet-Eating Stars Hint Earth’s Fate: What Our Sun Will Do
Introduction: A distant, fateful horizon Our Sun is about halfway through its life, which means Earth is in the middle of its own planetary journey. As astronomers continually refine models of stellar evolution, a striking image emerges: stars like the Sun are not static sentinels but dynamic engines that will eventually reshape the worlds orbiting…
