| Description |
English: Shown here is the partial lunar eclipse of 19 November 2021 as seen from Kitt Peak National Observatory, a Program of NSF’s NOIRLab. This Image of the Week captures the eclipse above the Nicholas U. Mayall 4-meter Telescope in the Arizona-Sonoran Desert of Arizona. While technically a deep partial eclipse with 97% of the Moon in Earth’s shadow, or umbra, this eclipse was deep enough to give the Moon a pronounced red tint and decrease its brightness. The only light the Moon ever “shines” with is reflected sunlight. But while the Moon is within the umbra, the sunlight illuminating the Moon is scattered by Earth’s atmosphere. Essentially passing through a prism, the sunlight refracts in Earth’s atmosphere and takes on a crimson hue, which then illuminates the Moon. This hue can be seen in this image, taken on the same night through a 600-mm focal length camera lens (equivalent to a small telescope). Despite being dimmed in the eclipse, the Moon still brightens the dome of the Mayall telescope witha red glow. The next total lunar eclipse will take place on 15–16 May 2022, and will be visible over the Americas and parts of western Europe and Africa.
Ab: En la fotografía se puede apreciar el eclipse lunar parcial del 19 de noviembre de 2021 visto desde el Observatorio Nacional Kitt Peak, un Programa de NOIRLab de NSF. Esta Imagen de la Semana muestra el eclipse justo sobre el Telescopio de 4 metros Nicholas U. Mayall en el Desierto de Arizona-Sonora.
Aunque técnicamente éste fue un eclipse parcial con un 97% de la Luna en la sombra de la Tierra (o umbra), fue lo bastante profundo como para dar a la Luna un intenso color rojo y disminuir su brillo. La única luz con la que la Luna “brilla” es la luz que proviene del Sol, pero cuando la Luna se encuentra dentro de la umbra, la luz solar que la ilumina se dispersa por la atmósfera terrestre. Al pasar por un prisma, la luz solar se refracta en la atmósfera terrestre y adquiere un tono carmesí que ilumina la Luna. Esta tonalidad puede verse en esta imagen, que fue tomada esa misma noche con un lente de cámara de 600 mm de distancia focal (equivalente a un pequeño telescopio). A pesar de estar atenuada por el eclipse, la Luna sigue iluminando la cúpula del telescopio Mayall con un brillo rojo. El próximo eclipse total de Luna sucederá los días 15 y 16 de mayo de 2022, y será visible sobre el continente americano y partes de Europa occidental y África |
