Guiyang — Com a ajuda do Radiotelesc\u00f3pio Esf\u00e9rico de Abertura de Quinhentos Metros (FAST, na sigla em ingl\u00eas), tamb\u00e9m apelidado de “Olho do C\u00e9u da China”, os cientistas identificaram mais de 500 novos pulsares desde outubro de 2017.<\/p>\n\n\n\n

Pulsares, ou estrelas de n\u00eautrons girando rapidamente, originam-se dos n\u00facleos implodidos das estrelas moribundas maci\u00e7as atrav\u00e9s de explos\u00f5es de supernovas. Com sua alta densidade e r\u00e1pida rota\u00e7\u00e3o, eles s\u00e3o um laborat\u00f3rio ideal para estudar as leis da f\u00edsica em ambientes extremos.<\/p>\n\n\n\n

Utilizando o FAST, os cientistas tamb\u00e9m detectaram 1.652 explos\u00f5es independentes provenientes de uma \u00fanica fonte de explos\u00e3o r\u00e1pida de r\u00e1dio (FRB, na sigla em ingl\u00eas) repetida, de codinome FRB121102, anunciou Li Di, cientista-chefe do telesc\u00f3pio e pesquisador dos Observat\u00f3rios Astron\u00f4micos Nacionais sob a Academia Chinesa de Ci\u00eancias.<\/p>\n\n\n\n

\u00c9 o maior conjunto de eventos FRB j\u00e1 detectados na hist\u00f3ria, explicou Li, acrescentando que esses resultados foram publicados na revista Nature em outubro.<\/p>\n\n\n\n

Os cientistas acreditam que isso pode ajudar a esclarecer as origens dos chamados “sinais misteriosos do espa\u00e7o profundo”.<\/p>\n\n\n\n

Li assinalou que eles receberam cerca de 200 pedidos de observa\u00e7\u00e3o de 16 pa\u00edses desde mar\u00e7o, quando o FAST abriu oficialmente para o mundo.<\/p>\n\n\n\n

Localizado em uma depress\u00e3o k\u00e1rstica natural profunda e redonda na Prov\u00edncia de Guizhou, no sudoeste da China, o FAST iniciou a opera\u00e7\u00e3o formal em janeiro de 2020. Acredita-se que seja o radiotelesc\u00f3pio mais sens\u00edvel do mundo.<\/p>\n","protected":false},"excerpt":{"rendered":"
