Answer: James Webb Space Telescope
Notes: Astronomers using the James Webb Space Telescope (JWST) recently detected phosphine (PH3) in the atmosphere of brown dwarf Wolf 1130C. Phosphine is a chemical compound consisting of one phosphorus atom and three hydrogen atoms. On Earth, phosphine is naturally produced by bacteria in low-oxygen environments. These bacteria absorb phosphate from minerals or biological material and combine it with hydrogen to form phosphine. Phosphine is also present in the atmospheres of Jupiter and Saturn. The compound is also known as hydrogen phosphide. Its detection in Wolf 1130C provides insights into chemical processes in brown dwarf atmospheres.
