We know this week’s teaser infrared image probably created a “duh” moment, but check out the visible light images to understand more about what Michael Stuart observed.
Answer: The first infrared image shows a pair of giraffes in the distance. The way that they are standing, it almost looks like the animal has a really long tail! The second infrared image shows a single giraffe at a closer distance. Notice how the spots are visible. Even under partial cloud-cover, solar loading can still be a factor—the “Big Heater in the Sky” is still there, pumping out energy. The darker color of the spots absorbs and emits more heat than the light colored fur. What would the Giraffe look like at night?
