New observations from the infrared Herschel Space Observatory reveal that an exploding star expelled the equivalent of between 160,000 and 230,000 Earth masses of fresh dust. This enormous quantity suggests that exploding stars, called supernovae, are the answer to the long-standing puzzle of what supplied our early universe with dust.
.“This discovery illustrates the power of tackling a problem in astronomy with different wavelengths of light,” said Paul Goldsmith, the NASA Herschel project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., who is not a part of the current study. “Herschel’s eye for longer-wavelength infrared light has given us new tools for addressing a profound cosmic mystery.”
