摘要

描述
Nederlands: Sterrenstelsel GN-z11
Ελληνικά: Ο Γαλαξίας GN-z11
English: Hubble Space Telescope astronomers, studying the northern hemisphere field from the Great Observatories Origins Deep Survey (GOODS), have measured the distance to the farthest galaxy ever seen. The survey field contains tens of thousands of galaxies stretching far back into time. Galaxy GN-z11, shown in the inset, is seen as it was 13.4 billion years in the past, just 400 million years after the big bang, when the universe was only three percent of its current age. The galaxy is ablaze with bright, young, blue stars, but looks red in this image because its light has been stretched to longer spectral wavelengths by the expansion of the universe.
Français : Les astronomes du télescope spatial Hubble, qui étudient le champ de l'hémisphère nord depuis le Great Observatories Origins Deep Survey (GOODS), ont mesuré la distance jusqu'à la galaxie la plus éloignée jamais vue. Le champ d'investigation contient des dizaines de milliers de galaxies s'étendant loin dans le temps. La galaxie GN-z11, montrée dans l'encart, est vue comme elle était il y a 13,4 milliards d'années, soit à peine 400 millions d'années après le Big Bang, lorsque l'univers avait seulement trois pour cent de son âge actuel. La galaxie est bordée de jeunes et brillantes étoiles bleues, mais qui semblent rouge dans cette image car la longueur d'onde spectrale de leur lumière a été étirée par l'expansion de l'univers.
