Hubble has three more years to live, and NASA's making the most of them. The latest from our favorite space telescope: a cobalt blue planet from the class known as "hot Jupiters."
NASA said Wednesday morning in an announcement that the planet, 63 light-years from Earth, would look like a deep blue dot if we were close enough to view it directly.
What causes the blue color of planet HD 189733b? It's likely glass, NASA explains, raining in the atmosphere. Sideways. Yes, you read that right.
This strange world, called a hot Jupiter because of its proximity to its parent star, could very well contain "high clouds laced with silicate particles," according to the space agency. The silicates condense in the planet's extreme heat -- 2,000 degrees Fahrenheit. Winds of 4,500 mph hurl the small drops of glass through the atmosphere, which "scatters" the blue light.
