60 years ago today, humanity saw this for the first time.

On August 23, 1966, NASA's Lunar Orbiter I — a robotic spacecraft scouting the Moon for future landing sites — turned its camera around and captured something nobody had ever seen before: Earth, from the vicinity of the Moon.

The image was grainy. Black and white. Transmitted across nearly a quarter million miles to a tracking station near Madrid, Spain.

But it was the first time our planet was ever photographed from another world.

Two years later, Apollo 8's "Earthrise" would become the iconic version everyone remembers. This one came first — and quietly changed how we understood our place in the universe. 🌍

Say hi to our galactic neighbor! 👋

2.5 million light-years away is the Andromeda galaxy, the closest spiral galaxy to our own Milky Way.

Our night sky is becoming increasingly crowded. Thousands of satellites now orbit Earth, supporting communication, navigation, weather forecasting, science, and internet services. But the rapid growth of satellite constellations is also creating concerns for astronomers.

Bright satellites can leave streaks across telescope images, interfere with sensitive observations, and make it harder to study faint objects deep in the universe. Space agencies and astronomers are now working with satellite operators to reduce these effects.

The challenge is clear: How can we enjoy the benefits of a connected world while still protecting humanity’s view of the cosmos? 🌍✨🔭

🌍 Earth vs. Venus: Two Worlds, Two Very Different Days! 🟡

Earth completes one rotation on its axis in about 24 hours, giving us the familiar cycle of day and night. Venus, however, rotates extremely slowly—taking about 243 Earth days to complete one rotation.

[Physics-astronomy @Physicsastronmy]

What would happen if the Earth's rotation stopped for a moment?
