GJ 1132b is so close to its sun that it more likely resembles Venus than Earth. Astronomers estimate its average temperature to be about 700 degrees Fahrenheit, and that’s without taking into account the potential greenhouse effect of its atmosphere. Life as we know it can’t be supported. ? We deploy a suite of tests to verify the reliability of the transmission spectrum, which are greatly helped by the existence of repeat observations. The large z-band transit depth indicates strong opacity from H2O and/or CH4 or a hitherto-unconsidered opacity. A surface radius of 1.375 ± 0.16 allows for a wide range of interior compositions ranging from a nearly Earth-like rocky interior, with ~70% silicate and ~30% Fe, to a substantially H2O-rich water world” the scientists descrived their discovery.
