beyond on Instagram: "While we often see the Sun as yellow, orange, or even red from Earth, that’s not its true color. Our atmosphere scatters shorter wavelengths of light — like blue and violet — through a process called Rayleigh scattering. What’s left reaching our eyes are the longer wavelengths, which makes the Sun appear warm-toned. But in space, without atmospheric interference, the Sun appears pure white. That’s because it emits all visible wavelengths at once, like a compressed rainbow m

Sekolahnesiaa on Instagram: "Langit terlihat berwarna biru jika dilihat dari Bumi karena adanya fenomena fisika yang disebut Hamburan Rayleigh (Rayleigh Scattering). Cahaya matahari yang kita lihat tampak berwarna putih, tetapi sebenarnya terdiri dari spektrum semua warna pelangi (Merah, Jingga, Kuning, Hijau, Biru, Nila, Ungu). Setiap warna ini memiliki panjang gelombang yang berbeda-beda. Ketika sinar matahari memasuki atmosfer Bumi, ia bertabrakan dengan molekul-molekul gas yang sangat kecil,

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
