James Webb Telescope Sheds New Light on Crab Nebula's Origins
Latest data from the James Webb Space Telescope provides fresh insights into the Crab Nebula's unusual supernova explosion.
- Scientists used Webb's MIRI and NIRCam to study the Crab Nebula's composition and history.
- The Crab Nebula resulted from a core-collapse supernova observed in 1054 CE.
- New findings suggest the explosion could be either an electron-capture or a weak iron core-collapse supernova.
- Webb's measurements show a modestly elevated nickel to iron ratio, refining previous estimates.
- High-resolution maps reveal distinct dust distributions within the Crab Nebula.
