yes, we are heading for an apocalypse.
///The most likely scenario for the total annihilation of Earth? Being engulfed into the Sun as it transforms into a ‘red giant’ star. As the Sun’s thermonuclear fuel, hydrogen, becomes depleted in its core, our star’s outer envelope will begin to expand. In this phase of its evolution, the Sun will lose a significant amount of mass, meaning Earth’s orbit will also expand.
However, current theory suggests the new orbit won’t be large enough for the Earth to escape interaction with the lower atmosphere of the expanding Sun. This means Earth will likely still be vaporised by the growing star.///

You've got about 8 billion years to wait but you can start panicking any time, I suppose.
