HD 189733b: The Glass Rain Planet

Scientists discovered HD 189733b. From space, it's a gorgeous blue marble floating

in the void. Up close, that blue isn't water. It's shattered silicate

particles whipping through a searing atmosphere. Imagine standing there. Shards tear through you horizontally,

while you're simultaneously cooked alive. What keeps me up at night: If life exists,

it evolved to survive that nightmare. Every assumption about what life needs, where it can

exist, could be completely wrong. The universe isn't just stranger than

we imagine. It's stranger than we can imagine.
