People venture up high mountain peaks to enjoy the warm colors of the fall leaves.

Here’s a view from a bit higher. This Earth satellite image shows the autumn colors as they sweep across the eastern United States and Canada. According to The Foliage Network, fall colors were at or just past their peak in much of upstate New York and the upper peninsula of Michigan the day before this image was captured. As seen in the Adirondack Mountains and Catskill Mountains in New York, peak color comes to high-elevation areas before surrounding lower-elevation areas. Credit: NASA
Crescents belonging to two of Saturn’s moons – Rhea and Titan – show off their vast differences.

Rhea is a heavily-cratered, airless world, while Titan’s nitrogen-rich atmosphere is even thicker than Earth’s. This natural color image was taken in visible light by the Cassini spacecraft on Nov. 19, 2009, at a distance of approximately 713,300 miles (1,148,000 kilometers) from Rhea. After a nearly 20-year mission that overflowed with discoveries, the Cassini spacecraft ended its mission on Sept. 15, 2017.
