Happy #FallEquinox! 🍂 Today, the Sun crosses Earth’s celestial equator, marking the official start of autumn in the Northern Hemisphere. It's also the time of year when day and night are nearly equal in length around the globe.

Look up tonight.

The Moon will pass through Earth's shadow during a deep partial lunar eclipse visible from much of North and South America and parts of Europe and Africa. As the eclipse deepens, the Moon will appear tinged with shades of red and copper.

#FunFactFriday: A day on Venus is longer than a year on Venus! 🔭 Venus takes about 243 Earth days to rotate once, but only 225 Earth days to orbit the Sun. ☀️ For comparison, Earth rotates once every 24 hours, while Mars takes about 24 hours & 37 minutes. 🌏
