Studying the universe at infrared wavelengths enables astronomers to detect stars and planets forming, to view the supermassive black holes at the center of our galaxy through obscuring clouds of interstellar dust, to understand the life cycle of organic substances in space, and to determine the chemical composition of comets, asteroids, and planetary atmospheres.
CO emission observed by SOFIA/GREAT (12CO 11-10) and APEX (other lines) from supernova remnant W28.
Observations of supernova remnant W28 were made with the GREAT far-IR spectrometer during SOFIA’s Early Science program in 2011.
W28 is located in the inner part of the Milky Way Galaxy, near a large star-forming complex with HII regions including the well-known Trifid Nebula (Messier 20). W28 is about six thousand light-year from Earth and the supernova remnant is estimated to be about 20,000 years old.
