Venus-like exoplanet might be 1st to have oxygen
According to a research, a Venus-like exoplanet called GJ 1132b, situated 39 light-years from Earth, might be the first exoplanet to have an oxygen atmosphere. The abundant ultraviolet on the planet breaks water molecules into oxygen and hydrogen. However, scientists claim that oxygen could not be a sign of life because of its high surface temperature of about 230 °C.
