Our Third Dimension | Space Science Universe on Instagram: "⚠️Info: Watch the blue fade to black from inside the rocket. By roughly 70,000 to 80,000 feet the sky is already very dark, and by around 100,000 feet it appears essentially black. The reason is simple physics. As altitude increases, the air thins rapidly, so there are far fewer molecules to scatter sunlight toward the camera. With Rayleigh scattering greatly reduced, the sky loses its blue and space reveals itself as a black backdrop.

ORMOUS 🌒 on Instagram: "The Blood Moon is not merely beautiful—it is a cosmic display of celestial mechanics at its finest. During a total lunar eclipse, the Moon enters Earth’s umbra, and sunlight passing through Earth’s atmosphere is scattered. Only the longer red wavelengths survive the journey, casting a crimson hue upon the Moon’s surface. This spectacle exemplifies the profound interaction between light, atmospheric composition, and orbital dynamics. The red glow isn’t mythical—it is the
