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.

NASA honors the memory of Dolly Parton, who passed away on Aug. 25, 2026. In 1989, Dolly performed at @NASAJohnson's Rocket Park, alongside fellow musicians Willie Nelson and Kenny Rogers, to an audience of over 12,000 NASA employees and their families.

#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. 🌏

#DidYouKnow Raindrops aren’t tear-shaped! 💧 Small raindrops are nearly spherical thanks to surface tension. As they grow larger and fall faster, air resistance flattens them into a shape more like a hamburger bun. 🌧️ #FunFactFriday

There is more than meets the eye in this photo… The ring around the central galaxy cluster is evidence of dark matter, the invisible glue holding the universe together. Dark matter doesn’t emit, reflect, or absorb light, but it has gravity like ordinary matter. 🧵
