- New Chandra data of the supernova remnant G11.2-0.3 raise new questions about the timing of its origin.
- Previously, G11.2-0.3 was associated with an event recorded by Chinese observers in 386 CE.
- Chandra observations show that dense gas clouds lie along the line of sight between Earth and G11.2-0.3.
- This new information means that the supernova explosion would have been too faint to be seen with the naked eye from Earth.
