...exhibited a ‘dispersion’ sweep characteristic of all pulsars. Pulsars are ultra dense, rotating neutron star remnants of a supernova explosion in our Galaxy, which emit jets of radiation along their poles. As the pulsar spins, these jets of radiation...
... bright star, before slowly fading from sight over several weeks or months. However the maximum intensity of a supernova explosion occurs after the shock wave and it is this period of peak brightness that is normally studied by astronomers. Therefore...
.... This is the first time that researchers have found three concentric expanding supernova shells. Superbubbles are created by strong stellar winds and supernova explosions of individual stars, and are very varied in size and structure. The reason...
... galaxy looking for something else. The space telescope had originally been set up to observe a gravitationally lensed supernova explosion nicknamed “Refsdal” in the galaxy cluster MACS J1149-2223, when it unexpectedly picked up the LS1 point source...
... movies and a three-dimensional model so that the public can ‘see’ a supernova explosion in as much detail as they possibly can. Just over three decades a go, supernova 1987A (SN 1987A), lit up the sky with the power of 100 million suns...
... through nuclear fusion reactions, towards the ejection of stellar debris into interstellar space via winds and supernova explosions. Interstellar gas, enriched with newly produced nuclei, will eventually cool down to form new stars, hence...
