Last week, NASA released animated artists’ conceptions of Io based on data Juno collected during two flybys. John Yang reports.

The habitable zone is the region around a star where an orbiting planet could host liquid water and, therefore, possibly support life. The habitable zone is also known as the "Goldilocks zone" because planets orbiting at that "just right" distance from a star are not too hot or too cold to host liquid water. If planets are closer to their star, the water turns to steam; if they're farther, it freezes.

Planetary defense is the effort to monitor and protect Earth from asteroids, comets and other objects in space. Earth's gravity attracts more than a hundred tons (more than 90 metric tons) of small objects and dust from space daily, according to NASA. Most of this material burns up in the atmosphere without any effect on the planet; larger chunks may produce a bright streak of light that's visible in the night sky or a small meteorite for a rock hunter to find.
