Earth's Atmosphere Extends Far Beyond Our Planet's Surface

Uranus has an axial tilt of 97.77°, meaning it essentially rolls around the Sun on its side. This extreme tilt means each pole faces the Sun for 42 continuous years at a time. With a year spanning 84 Earth years, each of Uranus's four seasons lasts approximately 21 years.

In 2002, astronomers Karl Glazebrook and Ivan Baldry at Johns Hopkins University calculated the average color of the universe by analyzing light from over 200,000 galaxies. The result is a pale, creamy beige — officially named 'Cosmic Latte'.

The Sun accounts for approximately 99.86% of all the mass in our solar system. Of the remaining 0.14%, Jupiter alone makes up about 71%, leaving all other planets, moons, asteroids, and comets sharing a tiny sliver. Earth represents just 0.0003% of the solar system's total mass.

In microgravity, tears don't stream down a face — they form liquid bubbles that cling to the eye. The tear pools on the eyeball and can cause stinging. Chris Hadfield famously demonstrated this on the International Space Station, describing the sensation as 'your eyes cry but the tears don't fall'.
