White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

Finding a "teenage" white dwarf pulsar is particularly exciting because this phase of a star's life is so brief, Rodriguez explains. How brief? "About 40 million years," he says.

Our Sun will become a white dwarf in about 7 billion years. At that point, it will no longer produce energy through nuclear fusion, having exhausted its fuel (hydrogen and helium). Just like the ...
