An image of 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’s 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 scientist to find out which are the elements present in this supernova remnant.

[Image Description: This image shows a supernova remnant that looks like it has the texture of a dried apricot. The remnant shows a brightness variation, being brighter in the upper left part and darker in the bottom right. In the middle of the apricot-like structure is a bright yellow dot, which stands out on top of the darker orange colour of the remnant.]
