Pulsar wind is composed of charged particles; when it collides with the pulsar\u2019s surroundings, in particular with the slowly expanding supernova ejecta, it develops a PWN.<\/p>\n<p>Particles in PWNe lose their energy to radiation and become less energetic with distance from the central pulsar. Multiwavelength studies of these objects, including X-ray observations, especially using spatially-integrated spectra in the X-ray band, have the potential of uncovering important information about particle flow in these nebulae. This could unveil important insights into the nature of PWNe in general.<\/p>\n<p><a href=\"https:\/\/phys.org\/news\/2019-05-astronomers-pulsar-nebula-da.html\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<div style=\"clear:both;\">Read more<\/div>\n<p><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Astronomers have carried out a multiwavelength investigation of a pulsar wind nebula (PWN), designated DA 495, to unveil its mysterious physical nature.
