CABO CA\u00d1AVERAL, Florida.- <\/em><\/strong>Los astr\u00f3nomos han descubierto lo que parecen ser enormes galaxias que datan de 600 millones de a\u00f1os despu\u00e9s del Big Bang, lo que sugiere que el universo primitivo pudo haber tenido una v\u00eda r\u00e1pida estelar que produjo estos \u201cmonstruos\u201d.<\/p>\n

Aunque el nuevo Telescopio Espacial Webb ha descubierto galaxias m\u00e1s antiguas, que datan de apenas 300 millones de a\u00f1os antes del comienzo del universo, es el tama\u00f1o y la madurez de estas seis aparentes megagalaxias lo que ha dejado at\u00f3nitos a los cient\u00edficos. El mi\u00e9rcoles dieron a conocer sus hallazgos.<\/p>\n

El principal investigador, Ivo Labbe, de la Universidad Tecnol\u00f3gica de Swinburne, en Australia, y su equipo esperaban encontrar peque\u00f1as galaxias tan cerca de los albores del Universo, pero no estos monstruos.<\/p>\n

Aunque la mayor\u00eda de las galaxias de esta era son a\u00fan peque\u00f1as y crecen gradualmente con el tiempo\u201d, explica en un correo electr\u00f3nico, \u201chay algunos monstruos que alcanzan r\u00e1pidamente la madurez\u201d. Se desconoce por qu\u00e9 ocurre esto o c\u00f3mo funcionar\u00eda.<\/p><\/blockquote>\n

Cada uno de los seis objetos parece pesar miles de millones de veces m\u00e1s que nuestro Sol. En uno de ellos, el peso total de todas sus estrellas podr\u00eda ser hasta 100.000 millones de veces superior al de nuestro Sol, seg\u00fan los cient\u00edficos, que publicaron sus hallazgos en la revista Nature.<\/p>\n

Labbe dijo que \u00e9l y su equipo no pensaron al principio que los resultados fueran reales \u2014 que no pod\u00eda haber galaxias tan maduras como nuestra V\u00eda L\u00e1ctea tan temprano en el tiempo \u2014 y que a\u00fan necesitan ser confirmados. Los objetos parec\u00edan tan grandes y brillantes que algunos miembros del equipo pensaron que se hab\u00edan equivocado. <\/p>\n

Est\u00e1bamos asombrados, algo incr\u00e9dulos\u201d, coment\u00f3 Labbe.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
