A Deep-Blue World
Hubble observations measured HD 189733 b’s visible-light color as deep blue. The color is associated with its hazy atmosphere and scattering by silicate particles — not an Earth-like ocean.

HD 189733 b is a hot Jupiter orbiting extremely close to its star. Hubble observations established its deep-blue visible-light color, while other observations have helped astronomers map temperatures and measure fierce atmospheric winds.
IMPORTANT DISTINCTION
“Raining glass sideways” is a vivid interpretation of the planet’s atmospheric conditions — not footage or a direct observation of glass shards falling. Silicate particles are implicated in its haze and blue appearance, and extreme winds have been measured; descriptions of glass rain connect those findings with atmospheric models.
