Habitable Moons at the Ice Line?

Those of us who love astrobiology get really worked up about the lack of Earth-sized exoplanets found at Earth-like distances from their stars. All we want, we who hope for lots of extraterrestrial life, is a bunch of Earth-like planets doing Earth-like things so we can feel better about the odds for lots of Earth-like life in the universe.

Exomoons disguised as aliens

Exoplanets with moons could mimic alien life-signs.

Pluto’s small satellites have very low escape velocities, which means that dust kicked up by impacts has a relatively easy time of escaping rather than settling back down to the little moon’s surface. Today’s paper looks at the fates of that dust.

The Many Moons of Pluto

The number of known moons of Pluto has now reached five. What are they like, and how did they get there? Kenyon and Bromley use numerical simulations to answer these questions and determine what else New Horizons may find in 2015.

Detecting Moons Around Exoplanets

Moons in other solar systems are common in science fiction. Are they common in the universe as well? Kipping et al. are using Kepler data to find out.
