There are plenty of planets in our universe that allow what we think is impossible to become possible. Let's take the planet HD189773-b as an example.
When we see it from the outside, it looks like a beautiful planet, although that beauty hides a dark secret. The planet is located 64 light years from us and looks like it does because it is made of silicate particles, the winds scream at a speed of 2km/s or 7200km/h. But the most absurd thing about the planet is that it rains glass from the side! With the strong winds, the glass rushes at 2km/s. To understand it easier, if this were to occur on Earth, it would travel around the Earth in 5 hours and leave lots of glass behind.
