Another Pale Blue Dot

NASA’s Hubble Space Telescope has captured an exoplanet’s true color. HD 189733b has an azure color that’s similar to Earth’s, but there is no chance the planet holds life as it orbits extremely close to its host star.

HD 189733b is a gas giant with an atmospheric temperature exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit), and some rather cruel weather. As NASA notes, HD 189733b is dominated by high winds that can reach speeds of 7,000 kilometers (4,350 miles) per hour, and it rains glass (!), based on previous data collected by NASA’s Spitzer Space Telescope. The azure planet is one of the closes exoplanets to Earth, just 63 light-years away, which makes it a prime candidate for research using Hubble or other telescopes.
