Cosmo Sight - Astronomy & science on Instagram: "We used just a tin of water, a thermometer, and sunlight to measure how much energy the Sun gives us — and it's mind-blowing. In direct sunlight, every square meter of Earth receives about 1 kilowatt of power. That's enough to light up 10 bulbs! Now imagine the Sun sending out that energy in all directions. It turns out the Sun emits around 400 million trillion trillion watts of energy every second. And we figured that out with just a basic experiment #physics #science #astrophysics" instagram.com
