🌍 Earth is often called the 'Blue Planet,' but did you know there's another fascinating blue world about 60 light-years away? Meet HD 189733b, a giant gaseous planet similar to Jupiter but much hotter, with surface temperatures soaring to 980°C (1800°F).
💨 This extreme exoplanet experiences winds up to 6,400 km/h (4,000 m.p.h.), making it a truly inhospitable place for life as we know it. What's even more astonishing is that it rains molten glass on HD 189733b! These rainstorms of glassy silicate particles give the planet its unique blue hue.
✨ HD 189733b is part of the "hot Jupiter" category, massive planets that orbit very close to their stars. These hot Jupiters are relatively easy to spot because they cause a significant drop in their star's light when they pass in front of it; HD 189733b, for instance, causes a three percent dip in its star's brightness.
The wonders of our universe never cease to amaze! 🌌
