Entender quién influye en su comportamiento ayuda a explicar cambios de brillo que antes no tenían causa clara. Para alguien de acá, es un recordatorio de que lo que se ve a simple vista puede ocultar otra historia. Como el estudio se basa en datos recientes, las conclusiones sobre la compañera todavía pueden ajustarse con nuevas observaciones.","quienFirma":"Phys.org (divulgación)","confianza":"divulgacion","consulta":null},"sello":{"hash":"0a6c990e0d66574dfe28eacb5ddd43ac7e844dcdb13be84bfaea18199a17f1fb","sello":"26903ded79683bee50fa9f0b9913ccced69fa3844620341205db417ba960be29","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6589410,"aleatorio":"aae3fca11cf193e281b136f05a8f62dbb956b185947e64c1f9fc3874eb3786bd","tiempo":"2026-10-27T15:02:00.000Z"},"nist":{"cadena":2,"pulso":2001772,"salida":"0E703280D2ECB99CF237148891BE4B05125CA4A9FA93BA99C93DE108693398FC1C1436A917C2E942D3FD99D4FACCDDC40E70589522F4EEDE9B18514294B0BD55","tiempo":"2026-10-27T12:55:00.000Z"},"noAntes":"2026-10-27T15:02:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 15:02:23 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Radio images reveal disturbances from Betelgeuse's mysterious companion that lurks within its shadows","descripcion":"The well-known star Betelgeuse has a mysterious houseguest—and it's shaking the rafters, rattling the pipes and slamming the cupboards (metaphorically speaking).

New data suggest that its recently discovered companion star, Siwarha, is the one doing the haunting.","pubDate":"Tue, 27 Oct 2026 11:00:08 EDT","url":"https://phys.org/news/2026-10-radio-images-reveal-disturbances-betelgeuse.html"},"indexado":"2026-10-27T15:01:32.924Z"}}
