On the day of the Cassini's grand finale, we're counting down the Saturn probe's most incredible moments and discoveries

Photo of the Day: The edge of the Morning Glory Pool at Yellowstone National Park. This pool's astounding color comes from the thermophilic bacteria within. But decades of vandals throwing objects into the pool have ruined its colors and given it a new nickname—"Fading Glory."

The #AgeOfAerospace continues tomorrow morning on Discovery!

Photo of the Day: The Cassowary is a flightless bird with a bright blue face and neck. They are closely related to the emu.
