Caption:<\/strong> An image of supernova remnant Puppis A in X-ray light, taken as part of the test and calibration campaign of Einstein Probe. Puppis A is the remnant of a supernova explosion that occurred 4000 years ago, the bright dot in the centre is the remnant star. The cloud-like structure surrounding it comes from hot material generated and expelled during the supernova. Einstein Probe\u2019s Follow-up X-ray Telescope (FXT) took this image. Accompanying this image, FXT also delivered a spectrum of the source tracing the energy distribution of its light. This enables scientists to find out which are the elements present in this supernova remnant.
