- There are more stars in the observable universe than grains of sand on all of Earth's beaches—estimated at 10^24 stars versus roughly 10^18 to 10^19 grains.
- The largest known structure in the universe is the Hercules-Corona Borealis Great Wall, a galactic filament spanning roughly 10 billion light-years.
- Saturn's moon Titan has lakes and rivers of liquid methane and ethane, making it the only body in our solar system besides Earth with stable surface liquids.
- The footprints left by Apollo astronauts on the Moon will likely remain visible for millions of years because there is no wind or water to erase them.
