NASA Measures All the Sun’s Energy to Earth

The video explains how solar energy from the sun affects Earth, highlighting the regular solar cycles and their minimal variation in energy output. It discusses the importance of understanding this energy balance for climate change research. NASA's TSIS mission aims to provide accurate solar energy measurements to better isolate and quantify other influences on Earth's climate.

What do the 100 pennies represent in the context of the video?
