Titan’s Missing Waves

Titan (or Saturn VI) is the largest moon of Saturn. It is the only natural satellite known to have a dense atmosphere and the only object, other than Earth, for which clear evidence of stable bodies of surface liquid has been found. However, these bodies of liquid are incredibly still, with no sign of wave activity. What is causing this incredible phenomenon?

Total Eclipse of the Sun

How can the shadow of the tiny moon eclipse the sight of the gargantuan sun? By sheer coincidence, the disc of the sun is 400x larger than the disc of the moon, but it’s 390x farther from Earth — which means that when they align just right, the moon blocks all but the sun’s glowing corona. Andy Cohen details this extraordinary celestial phenomenon (and when it will next occur).

Venus: Death of a Planet

Why did Earth thrive and our sister planet, Venus, die? From the fires of a sun’s birth… twin planets emerged. Then their paths diverged. Nature draped one world in the greens and blues of life. While enveloping the other in acid clouds, high heat and volcanic flows. Why did Venus take such a disastrous turn?
