Located 50 light-years away, the planet GJ 1214 b has defied 15 years of attempted observations due to its hazy nature.

Studying other planets is difficult not only because they are so far away, but also because they can have properties that make taking readings much harder. Here in our solar system, we only have scant information about the surface of Venus because its thick atmosphere makes it hard to view. Being 50 light-years away, the planet GJ 1214 b has proved similarly tricky, defying 15 years of attempted observations due to its hazy nature.

This water vapor may have contributed to the haziness of the atmosphere, which made observations difficult. However, the main culprit compound causing the reflectiveness remains unknown. “The planet is totally blanketed by some sort of haze or cloud layer,” said lead author Eliza Kempton of the University of Maryland in a statement. “The atmosphere just remained totally hidden from us until this observation.
