Stellar murder: when stars destroy and eat their own planets

Earth may have another five billion years to go, but we will not be here to witness its extinction. As the Sun burns through its hydrogen stores, it steadily grows brighter: every billion years, its luminosity increases by about 10%.

A billion years from now, the Sun will be bright enough to boil away Earth’s oceans.

So, the next time you bask in the warm rays of the Sun, remember: it’s got it in for us.
