Summary
| Description |
English: This artist’s impression shows a galaxy in the distant Universe, just two billion years after the Big Bang, in the process of pulling in cool gas (shown in orange) from its surroundings. Astronomers have been able to find out a lot about this object by studying not just the galaxy, but also the light of a much more distant quasar (the bright object to the left of the central galaxy), which happens to be in the right place to shine through the accreting gas. The motions of the gas and its composition fit very well with theories of cool gas accretion as a way of feeding star formation and galaxy growth. Español: Esta impresión artística muestra una galaxia en el universo distante, justo dos mil millones de años tras el Big Bang, en el proceso a través del cual atrae gas frío (en colores anaranjados) de los alrededores. Los astrónomos han podido obtener mucha información de este objeto estudiando no solo la galaxia, sino también la luz de un cuásar aún más alejado (el brillante objeto que se encuentra a la izquierda de la galaxia central), que se encuantra justo en el sitio adecuado para brillar a través del gas acretado. Los movimientos del gas y su composición encajan perfectamente con las teorías de acreción de gas frío como forma de alimentar la formación estelar y el crecimento de la galaxia. |
