Examplesofsupernovasupernova They are created inside a star's core and are spread all over space duringsupernovaexplosions. From theCambridge English Corpus We are also reminded that the waves are ripples in the fabric of space and time produced by violent energetic events such as exploding supernovae. From theCambridge English Corpus Thesesupernovaexplosions are a source of enrichment of the chemical composition of the interstellar medium. From theCambridge English Corpus The shockwave formed by this sudden collapse causes the rest of the star to explode in asupernova. From theCambridge English Corpus Experiments to produce a hydrodynamically unstable spherically diverging system of relevance to instabilities in supernovae. From theCambridge English Corpus Possible radiation sources include flares from late-type parent stars, gamma-ray bursts, and gamma-ray lines from supernovae. From theCambridge English Corpus Most cosmic rays will scatter and add a contribution comparable to the background from supernovae. From theCambridge English Corpus They paid particular attention in the inner region to having an environment free of what they refer to as 'life-extinguishing ' supernovae. From theCambridge English Corpus Fromsupernovato consciousness: evolution of iron-binding compounds. From theCambridge English Corpus Could a nearbysupernovaexplosion have caused a mass extinction? From theCambridge English Corpus Jets produced by these cones are used to study the physics of jets occurring in supernovae and in star-forming accretion disks. From theCambridge English Corpus Moreover, thesupernovairradiation would be spread out over a period of many months rather than seconds. From theCambridge English Corpus This situation is expected within cloud fragments near asupernova. From theCambridge English Corpus They are probably associated with some supernovae, producing narrow beams of radiation during gravitational collapse. From theCambridge English Corpus Such elements are the product of nucleosynthesis triggered in the extreme physical conditions that occur in thesupernovaevent itself. From theCambridge English Corpus These examples are from corpora and from sources on the web.
