James Webb Telescope Maps 3D Structure of Interstellar Dust and Gas

New observations reveal intricate layers and magnetic features in the interstellar medium illuminated by a centuries-old supernova.

  • NASA's James Webb Space Telescope captured detailed images of interstellar dust and gas illuminated by light echoes from a 350-year-old supernova.
  • For the first time, scientists have mapped the 3D structure of the interstellar medium, uncovering sheet-like formations and dense knots previously undetected.
  • The observations highlight the influence of interstellar magnetic fields, revealing magnetic 'islands' within the gas and dust structures.
  • The light echoes, first detected by the retired Spitzer Space Telescope, were studied in unprecedented detail using Webb's infrared imaging capabilities.
  • Future spectroscopic studies with Webb aim to analyze changes in the composition of the dust as it interacts with the supernova's light echoes.
