3. Moon's Roommate Drift

Talk about needing some space! The Moon is like that one roommate who's slowly and inconspicuously moving out, inch by inch, just to get a little breather: It's currently drifting away from Earth at a rate of 3.78 centimeters per year. Over billions of years, this could shake things up for life on Earth by causing our planet to slow down, but hey, we might have some cool moon-adapting technology by then!

4. Cosmic Tug-of-War Tides

When the moon and Sun can't decide who's got the bigger pull in our cosmic tug-of-war, they call on Mother Earth to give them some space and make waves: Both the moon's and the Sun's gravitational forces affect Earth's tides, resulting in more extreme tides called spring tides during full moon or new moon, and smaller tides called neap tides when their forces counteract. Winds and weather patterns, of course, also meddle in this watery feud.

6. Synchronous Rotation Peekaboo

For those avid moon watchers lamenting their never-ending game of peekaboo with the same side of our nightly neighbor, here's why the universe may have dished you a "Rocky Relationship": The moon's synchronous rotation keeps the familiar near side facing Earth, as it takes around 27 days to both rotate and orbit our planet. Yet, fear not, curious stargazers! We do occasionally get to sneak a glimpse of an extra 8 degrees on either side, all thanks to the mismatched dance between orbit and rotation.

11. Bright Full Moon Disco

Lunacy in the cosmos: Are you just feeling a little extra moo-dy, or is your neighbor's lunar lawn party getting out of hand? Fear not, for it might just be a full moon lighting up the dance floor! Funnily enough, a full moon can appear up to six times brighter than during its first or last quarter crescent phases, all thanks to the celestial hokey pokey of sunlight angles. However, don't expect a lunar tan anytime soon – the moon is still 400,000 times dimmer than the sun, and its disco-ball-esque brightness is being studied by the National Institute of Standards and Technology for calibrating Earth-observing satellites.

16. Total Eclipse Moon Fashion

Say goodbye to the blues, and hello to the reds: During a total lunar eclipse, the Moon sports a fashionable reddish-orange hue thanks to a phenomenon called Rayleigh scattering, caused by Earth's atmosphere filtering out the shorter wavelength colors, such as blue and violet. The shade of red the Moon struts varies based on the current atmospheric factors like dust particles, water droplets, clouds, and mist. If we were to attend this lunar fashion show from the Moon itself, Earth would be glamorously accessorized with a vibrant red ring, courtesy of all the sunrises and sunsets happening simultaneously.
