Summary
| Description |
English:
It looks as though the stars are falling through the sky above Gemini North, the northern-hemisphere-based half of the international Gemini Observatory, a Program of NSF’s NOIRLab. The stars, however, have not suddenly all shifted across the Universe. The trails of starlight are due to the movement of the Earth itself.
We know that the Earth rotates once on its own axis every 24 hours, giving us daytime and nighttime, but it is still strange to see such a visual reminder. The photographer, Jason Chu, took a very long exposure in order to capture the changing view of the stars as the Earth rotated. The result is this spectacular image with the faint red glow of the Gemini North laser guide star system emanating from its open dome, the taillight of a passing car crossing the dark road below and sweeping star trails in the background.
Español:
En esta imagen parece que las estrellas estuvieran cayendo del cielo encima de Gemini Norte, el gemelo boreal de los Telescopios Gemini que se encuentra en el hemisferio norte, un Programa de NOIRLab de NSF. Sin embargo, las estrellas no se han desplazado repentinamente por el Universo, lo que ocurre es que estos trazos de luz de estrellas se deben al movimiento de rotación de la Tierra.
Todos sabemos que la Tierra rota sobre su propio eje una vez cada 24 horas, dándonos el día y la noche, pero a veces es extraño para nosotros ver este registro visual del movimiento terrestre. El fotógrafo, Jason Chu, tomó una exposición muy larga para captar cómo cambian visualmente las estrellas durante la rotación de la Tierra. El resultado es esta espectacular imagen que muestra el tenue resplandor rojo del sistema de estrella guía láser de Gemini Norte que emana desde su cúpula abierta, las luces traseras de un auto que pasa por la oscura carretera de abajo, y de fondo, los extensos trazos de estrellas.
