Astronomers spot a 'phoenix planet' forming from the ashes of a dead star

Astronomers have flagged a candidate "Phoenix planet" — a world apparently forming from the debris of a star that already died. The object orbits a white dwarf, the burnt-out core left behind when the star shed its outer layers, and is still accreting material onto the stellar remnant. The discovery, published in Nature, suggests planets can be born a second time after one stellar generation ends, which researchers described as completely unexpected.
