HD 189733 b: Planet Washed by Glass Rains

HD 189733 b, an interesting planet not only for glassmen but for all astronomy enthusiasts; Tilkicik (Vulpecula) is a Jupiter-like (jovian) planet located in the constellation. I will upset the glazers a bit, but it is not a suitable place to live.

Due to its close proximity to its star and its high temperature, the planet, which has entered the “Hot Jupiter” class, is more extraordinary and interesting to the researchers than the billions of other planets in the universe. The hot Jupiters, as known, are locked in their stars with gravitational forces. In other words, the planet always shows its same face to HD 189733, which is a very young star like the Sun, in which it rotates in an orbit about 4.6 million kilometers away.
While the density of silicate particles in its atmosphere makes the planet like this, at the same time, these particles at temperatures of up to 2,000 degrees Celsius are raining glass on the planet. The glass you know, you didn't read it wrong! These glass particles are flying on the planet with a great speed of up to 7,000 km per hour.

Wind speed was also measured by looking at the movements made by the Spitzer Space Telescope, the first exoplanet whose glass map was measured, while passing through its star in ongoing research. With this feature, it seems that it will have a great influence on the search of air systems on the exoplanets. It was also confirmed with the data collected that the strong winds on the surface affected the temperature.

Below you see a diagram showing the temperature map of planet HD 189733 b with data from Spitzer.
While the brighter colors represent the high temperature, the hottest spot on the planet is not 0 (zero) longitude, facing directly to the star it faces with its star. The hottest spot is about 30 degrees east. (Image copyright: NASA / JPL-Caltech / H. Knutson / Astronomical Image of the Day)

The existence of such planets in the universe confirms the existence of planets that have extraordinary climatic types, as we know it. Although a lot of things are behind the veil, it gives us a sense of curiosity. Science and technology are advancing! Who knows what we will see…
