Dead star may be birthing a rare second-generation planet

Astronomers report the unexpected discovery of what appears to be a second-generation planet forming around a white dwarf, the dead remnant of a star. These worlds arise from material the dying star casts off, making them extraordinarily rare, and finding evidence of one around a white dwarf caught researchers off guard.

Why now: The finding challenges assumptions about where and how planets can form, since stars are normally thought to destroy their planetary systems when they die.
