NGC 7293, better known as the Helix nebula, is the nearest example of a planetary nebula, which is the eventual fate of a star, like our own Sun, as it approaches the end of its life. As it runs out of fuel, the star expels its outer envelope of gas outward to form a nebula like the Helix.

The Solar System’s Major Moons

Planetary Society | Emily Lakdawalla

The Solar System contains 18 or 19 natural satellites of planets that are large enough for self-gravity to make them round. (Why the uncertain number? Neptune’s moon Proteus is on the edge.) They are shown here to scale with each other. Two of them are larger than Mercury; seven are larger than Pluto and Eris. If they were not orbiting planets, many of these worlds would be called “planets,” and scientists who study them are called “planetary scientists.”

Pluto May Have Deep Seas and Ancient Tectonic Faults
In July 2015, we get our first close look at the dwarf planet Pluto and its moon, Charon, a fact that has scientists hypothesizing more than ever about what we might see there. One of the latest ideas put forward is that perhaps the collision that likely formed Pluto and Charon heated the interior of Pluto enough to give it an internal liquid water ocean, which also gave the small world a short-lived plate tectonics system, like that of Earth.
