Chandra Data Raises Questions about the Timing and Origin of Supernova Remnant G11.2-0.3

New Chandra data of the supernova remnant G11.2-0.3 raise new questions about the timing of its origin. Chandra observations show that dense gas clouds lie along the line of sight between Earth and G11.2-0.3, meaning that the supernova explosion would have been too faint to be seen with the naked eye from Earth. A new […]
