Nebula Thymolis is a term used in astronomy to describe a cloud of gas and dust in space. The pronunciations of both words are not immediately obvious, but can be broken down using phonetic transcription. "Nebula" is pronounced /ˈnɛbjʊlə/, with the stress on the first syllable and a schwa sound in the second syllable. "Thymolis" is pronounced /ˈθaɪməlɪs/, with the stress on the second syllable and the "th" pronounced as a voiceless dental fricative. Together, they create a unique and scientific-sounding term for this celestial phenomenon.
