Astronomers found a planet 63 light-years away that appears as blue as Earth from space—but its colour comes from a scorching atmosphere where glass may rain sideways in 4,500-mile-per-hour winds - Space Daily

Astronomers have identified a planet about 63 light-years from Earth that appears strikingly blue when observed in visible light. The world, known as HD 189733b, has drawn attention because its color can resemble the blue look associated with Earth when seen from space.

That resemblance is misleading. Rather than oceans or a life-friendly atmosphere, researchers describe an extremely hot environment shaped by intense heat and violent weather. The planet’s blue appearance is linked to conditions in its atmosphere, not to anything like the calm skies or water that give Earth much of its color.

According to the report, HD 189733b may experience glass rain driven sideways by winds reaching around 4,500 miles per hour. Combined with the planet’s scorching temperatures, those conditions make it one of the more hostile exoplanets highlighted by astronomers, despite its visually beautiful color.

The finding underscores how deceptive distant planets can be when judged by appearance alone. HD 189733b may look serene from afar, but current observations point to a brutal world where extreme heat, fast-moving winds and unusual atmospheric chemistry create a far different reality.
