Summary
[edit]
| Description |
English: Gemini North, of the international Gemini Observatory (a Program of NSF’s NOIRLab), stands peacefully in the foreground, under a crystal clear sky. The dramatic upward sweep of milky and sooty patches of the Milky Way galaxy is seen in the background. The dark tendrils that permeate the Milky Way are due to enormous clouds of cosmic dust. These clouds of tiny particles absorb and scatter light, making huge patches of the Milky Way appear dark to human eyes from our vantage point here on Earth. Telescopes such as Gemini North, however, see the night sky differently. They are designed to collect far more light that the human eye can, thanks to their large primary mirrors. They can also detect ranges of light that humans cannot, meaning that they can probe areas of cosmic dust, giving us information on things that would otherwise remain obscured.
Español: El telescopio Gemini Norte, parte boreal del Observatorio Gemini (un Programa de NOIRLab de NSF), protagoniza el primer plano de esta imagen, bajo un cielo cristalino. Pero si entrecierras los ojos, da la sensación que el telescopio del fondo estuviese en llamas, enviando columnas de humo hacia el cielo estrellado. Por suerte, el vecino más cercano de Gemini Norte no se está incendiando, y ese espectacular “humo blanco” que se proyecta hacia el cielo, corresponde a nuestra galaxia, la Vía Láctea.
Los filamentos oscuros que se extienden en la Vía Láctea son enormes nubes de polvo cósmico. Estas nubes de pequeñas partículas absorben y dispersan la luz, formando enormes manchas oscuras para los ojos humanos desde nuestra perspectiva aquí en la Tierra. Sin embargo, telescopios como Gemini Norte observan el cielo de forma distinta: Gracias a sus grandes espejos primarios, están diseñados para recoger mucha más luz que el ojo humano. Además, tienen la capacidad de detectar rangos de luz que los ojos humanos no pueden, lo que significa que pueden sondear estas oscuras áreas de polvo cósmico, dándonos información de cosas que de otra forma permanecerían ocultas. |
