Universe
At its birth, Earth had no Moon. Then something perhaps the size of Mars slammed into the young planet, flinging molten debris into orbit that became the companion world now pulling our tides, steadying our seasons, and perhaps helping make Earth stable enough for life to flourish.
For a decade the Pink Planet was too faint for any ground telescope to study — and when James Webb finally caught its spectrum, the best fit to the light was an atmosphere hazed with salt clouds
From Ripples To Giants: The Fascinating Physics Behind Ocean Waves And Their Energy Journey
The Andromeda galaxy is the most distant thing you can see with the naked eye, and the light reaching your eyes from it tonight left some 2.5 million years ago, long before our own species existed.

When NASA lost contact with the Pioneer 10 spacecraft in January 2003, it was more than 12 billion kilometres from Earth and still faintly transmitting on a 30-year-old transmitter weaker than a refrigerator bulb, and the final signal took eleven hours to crawl back across the void before fading into noise forever.
The leading explanation for how the Moon was born is that a world the size of Mars called Theia slammed into the young Earth and flung out the debris that became the Moon, and recent research suggests Theia itself never fully left, with two continent-sized blobs buried near our planet’s core possibly being the last remains of the world that struck us.

Deep inside Neptune and Uranus the pressure is thought to crush carbon into diamonds, which then sink slowly through the planet as a glittering rain
Sunsets on Mars glow blue rather than red, because the fine dust suspended in its thin air scatters sunlight so that the blue gathers into a halo around the setting sun while the rest of the sky stays yellow and orange, leaving the planet that looks rusty all day to end it with a cool blue glow.
Pluto takes about 248 Earth years to circle the Sun, which means it still hasn’t completed a single orbit since we found it — and won’t finish that first lap until the year 2178
