Are Water Worlds Just Made of Soot?

Astrobites reports on whether the low-density planets that keep popping up in our growing collection of exoplanets are really the water worlds that we imagine them to be.

New research suggests that ultra-long-period pulsars might begin their lives as massive stars in close binary systems.
