The horizon melts into veils of green, violet & gold that don’t quite belong to this world, but to a dream the cosmos lets fall upon the Earth.

For a moment, the cold turns warm, as if the air itself were holding an ancient promise.
And u realize there’s beauty that can’t be explained, only lived.

(Yes, Venus is hotter than Mercury, even though Mercury is closer to the Sun. Its thick carbon dioxide atmosphere traps heat through a strong greenhouse effect, while Mercury lacks an atmosphere to retain heat.)

Mars sometimes appears to move backward in the night sky due to retrograde motion, an optical illusion. This happens when faster-orbiting Earth overtakes Mars. As Earth passes, Mars seems to slow, stop, and move westward, although it's still moving forward in space. 1/3
