Pero en el universo temprano, los astros estaban mucho más apretados, y eso cambió la forma en que se formaron las galaxias que conocemos. Para nosotros, es una pista de que aquello que parece normal ahora fue una excepción reciente. Las propias lecturas de la nota son indirectas, así que conviene tomarla como una hipótesis que todavía se está poniendo a prueba.","quienFirma":"Telescopio Espacial James Webb (NASA, ESA y CSA)","confianza":"divulgacion","consulta":null},"sello":{"hash":"1a011ec97be3c3be1a9e295f1ee857949cc74f19c8749ad620956931647a54b9","sello":"9d5b8d90bb0521998e79f5e4490effb3ea96550fda72d30c72283c02ec4b3f2a","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6586529,"aleatorio":"f15d143b6c1a01c2b5466c545c538dc958217fa6bd7c0093aebcc8ef576f3198","tiempo":"2026-10-26T15:01:30.000Z"},"nist":{"cadena":2,"pulso":2000458,"salida":"99993DC0D8DDC034F50376AE8A6FAD8A9DE1D55340BF57DC854EDBAE0B774C9F476C4366B2BE9210DAE98848CCFE3BC43D2151D50076C399E005422806FC5588","tiempo":"2026-10-26T15:01:00.000Z"},"noAntes":"2026-10-26T15:01:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 26 15:02:02 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Stellar collisions may have been common when the universe was young","descripcion":"In our solar system's corner of the galaxy, stars rarely collide. It makes sense: Space is vast, and stars have room to roam. Even in most of the present-day universe, stellar collisions are rare. The James Webb Space Telescope, however, peers deep enough into space to see the universe as it was not too long after the Big Bang. Its observations have revealed extraordinarily compact stellar systems, raising the possibility that collisions between stars were once much more common.","pubDate":"Mon, 26 Oct 2026 11:00:32 EDT","url":"https://phys.org/news/2026-10-stellar-collisions-common-universe-young.html"},"indexado":"2026-10-26T15:01:32.646Z"}}
