For the first and perhaps the last time ever, NASA's Cassini spacecraft, whose mission is to orbit Saturn, has captured a new moon emerge from the jovian planet's rings. As you might know, the birth of a moon is an extremely rare event, and in Saturn's case, it might never happen again. You see, there's a theory that the sixth planet from the sun used to have a much larger ring system, which led to formation of numerous natural satellites. After birthing a whopping 62 moons, though, the rings are now too depleted to make more, even if they still look lush from afar. This could be our very last chance to observe how Saturn's ring particles form a natural satellite that detaches from the planet and ultimately orbits around it.
