Dust to Dust: Dying Star System Spied

Stars like the sun eventually run out of hydrogen fuel and puff-up into red giants at the end of their lives — a precursor to a suicidal shedding of gas, decimating any nearby planets, eventually leaving a tiny white dwarf remnant. But a nearby star, located around 100 light-years away, has been spotted in the brief stage before the red giant phase of its death throes — and it has a dusty disk usually exclusive to young stars.
