The Weekly Did You Know: Optical Phenomena

Have you ever wondered why you see “puddles” when you are driving on a hot day? This is caused by an optical phenomenon called an inferior mirage- where cold air sits above warm air and bends light downward. The “puddle” you see on the road is just a reflected image of the sky above. However, the opposite mirage, a superior image- where warm air sits above cold, is the reason behind people claiming to see boats floating in the air. This is called fata morgana.

The Weekly Did You Know: Thanksgiving Turkey

You can increase your turkey cooking skills this Thanksgiving by trying out this easy tip from 1999. Harold McGee, a writer on food science, suggests chilling the breasts of your turkey as you allow the legs to come to room temperature. The breast meat will lower in temperature as the leg meat temperature will rise to about 60°F. This will give yourself the best odds to yield a perfectly cooked turkey as you give your dark meat to get a head start on coming to temp.

Remember to always check the internal temperature of the meat. Check out this link from the USDA covering the minimum safe temperatures: https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/food-safety-basics/safe-temperature-chart

The Weekly Did You Know: Penitents

Snow spikes, also known as penitents, form through the sublimation of snow at high altitudes. They occur naturally on glaciers and mountain ranges with low temperatures and humidities such as the Andes.

The spikes are created when throughs form on the surface of a glacier which absorb the sunlight thus causing the snow to sublimate. It is believed that these penitents may have the ability to preserve glaciers by blocking some of the light that would be absorbed by surrounding icy surfaces.

The Weekly Did You Know: Sun Dogs and Solar Halos

Solar Halo as seen on Hwy. 25 in Starkville, MS, 5 p.m. Central Time on October 21, 2023.

Solar halos and their associated colors are caused by redirection of rays of sunlight through ice crystals in the atmosphere (refraction), especially when high-altitude cirrus clouds are present. The bright spots to either side of the sun are called “sun dogs”.

Though commonly associated with the sun, halos can also occur around the moon.
