Cada punto luminoso de una fotograf\u00eda del cielo puede esconder una historia de miles de millones de a\u00f1os. Este 12 de noviembre, la misi\u00f3n europea Euclid<\/strong> ha abierto una ventana extraordinaria a esas historias con la divulgaci\u00f3n de su primer gran conjunto de observaciones: un inventario que abarca m\u00e1s de 900 millones de galaxias.<\/p>\n

El anuncio de la Agencia Espacial Europea (ESA) no significa que todas esas galaxias hayan sido descubiertas por primera vez. Su importancia reside en reunir observaciones de una poblaci\u00f3n gigantesca mediante un instrumento com\u00fan, con el prop\u00f3sito de estudiar la arquitectura del universo y los fen\u00f3menos que determinan su evoluci\u00f3n.<\/p>\n

UN ATLAS QUE TODAV\u00cdA EST\u00c1 NACIENDO<\/h2>\n

El archivo, denominado DR1-Foundation<\/em>, re\u00fane aproximadamente trece meses de trabajo y ocupa 1,7 petabytes. Incluye informaci\u00f3n espectral de m\u00e1s de 160 millones de fuentes. La superficie observada equivale a unas 9.500 lunas llenas, pero representa apenas una fracci\u00f3n del territorio celeste que la misi\u00f3n pretende cartografiar.<\/p>\n

Para entender el alcance de la empresa conviene imaginar un atlas terrestre que no se limitara a mostrar continentes y oc\u00e9anos, sino que tambi\u00e9n registrara c\u00f3mo cambiaron durante millones de a\u00f1os. En astronom\u00eda, la distancia proporciona precisamente esa dimensi\u00f3n temporal: cuanto m\u00e1s lejos se encuentra un objeto, m\u00e1s antigua es la luz que recibimos de \u00e9l.<\/p>\n

Una fotograf\u00eda por s\u00ed sola no permite conocer con exactitud la posici\u00f3n tridimensional de cada galaxia. Los astr\u00f3nomos necesitan informaci\u00f3n adicional sobre su luz. Al estudiar el desplazamiento de determinadas se\u00f1ales espectrales pueden estimar su distancia dentro de un modelo cosmol\u00f3gico y reconstruir la distribuci\u00f3n de las estructuras.<\/p>\n

LA GRAVEDAD COMO INSTRUMENTO DE OBSERVACI\u00d3N<\/h2>\n

Uno de los resultados m\u00e1s prometedores es la identificaci\u00f3n de aproximadamente 15.000 posibles lentes gravitacionales fuertes. El fen\u00f3meno aparece cuando la gravedad de un objeto situado entre nosotros y una fuente distante modifica el recorrido de la luz. En determinadas configuraciones, la imagen resultante adquiere forma de arco o incluso de anillo.<\/p>\n

Estas deformaciones no son defectos fotogr\u00e1ficos. Constituyen una herramienta para estudiar la distribuci\u00f3n de masa, incluso cuando parte de ella no emite luz. El desaf\u00edo consiste en distinguir las lentes aut\u00e9nticas de otras estructuras que pueden parecerse a ellas y analizar cada sistema con modelos adecuados.<\/p>\n

El cat\u00e1logo tambi\u00e9n incorpora decenas de millones de candidatos a cu\u00e1sares. Estos objetos deben su extraordinaria luminosidad a la materia que cae hacia agujeros negros supermasivos. Su estudio permite investigar la relaci\u00f3n entre los agujeros negros y las galaxias que los albergan.<\/p>\n

EL GRAN INTERROGANTE<\/h2>\n

La materia oscura y la energ\u00eda oscura siguen siendo conceptos fundamentales de la cosmolog\u00eda contempor\u00e1nea. La primera se infiere por sus efectos gravitatorios; la segunda se utiliza para describir la expansi\u00f3n acelerada del universo. Ninguna de las dos ha quedado explicada por completo.<\/p>\n

Euclid no ha resuelto esos enigmas con la publicaci\u00f3n de hoy. Lo que ofrece es una oportunidad de someter las explicaciones existentes a pruebas estad\u00edsticas mucho m\u00e1s exigentes. La comparaci\u00f3n entre la distribuci\u00f3n observada de galaxias y las predicciones te\u00f3ricas puede revelar d\u00f3nde funcionan nuestros modelos y d\u00f3nde necesitan revisarse.<\/p>\n

La participaci\u00f3n espa\u00f1ola incluye el trabajo del Instituto de Astrof\u00edsica de Canarias y otros centros en el desarrollo instrumental y la explotaci\u00f3n cient\u00edfica. El consorcio internacional re\u00fane tambi\u00e9n investigadores de Canad\u00e1, Estados Unidos y Jap\u00f3n.<\/p>\n

La siguiente entrega importante est\u00e1 prevista para mediados de 2027. Entretanto, el archivo reci\u00e9n abierto permitir\u00e1 que equipos de investigaci\u00f3n de todo el mundo formulen preguntas propias. El valor de Euclid no se mide solamente por la belleza de sus im\u00e1genes, sino por la posibilidad de convertirlas en evidencia cuantificable sobre el universo.<\/p>\n
