Submillimeter Wave Astronomy Satellite (SWAS)

The Submillimeter Wave Astronomy Satellite (SWAS) was a NASA spacecraft launched in 1998 to study the universe using submillimeter wavelengths, which are just beyond the infrared and microwave ranges. By capturing these signals, SWAS could investigate cold, dense regions of space where stars and molecules form, especially focusing on water vapor and carbon monoxide. Its observations helped scientists understand the chemical composition and physical conditions of interstellar clouds, offering insights into star formation and the interstellar medium. SWAS contributed valuable data that enhance our knowledge of the lifecycle of stars and the chemistry of the cosmos.
