The interstellar object #3I/ATLAS has sparked fascination bc, as it approached the Sun, it behaved in unexpected ways, brightening & showing a bluish tint instead of reddening. But none of this requires a non-natural explanation. As the object nears the Sun, its surface ices begin to vaporize. 1/7

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 #Mars #Science #Astronomy
