Summary
[edit]
| Description |
English: The aboveground portion of the McMath-Pierce Solar Telescope at Kitt Peak National Observatory (KPNO), a Program of NSF’s NOIRLab, is seen here at sunset. The McMath-Pierce Solar Telescope, located about 88 kilometers (55 miles) from Tucson, Arizona, saw its first light in 1962. It continued operating for an impressive 55 years until being decommissioned in 2017. For much of its life, it was the largest solar telescope on Earth. The McMath-Pierce telescope was unusual in that it used a large flat mirror called a heliostat to track the Sun across the sky and continually send sunlight down into an underground tunnel where the telescope itself was located. This helped to minimize hot air currents in the light path of the telescope, which would degrade the quality of the image. Though decommissioned, the McMath-Pierce Solar Telescope facility is being repurposed as the NOIRLab Windows on the Universe Center for Astronomy Outreach.
Español: En esta imagen de atardecer, podemos ver la parte superior exterior del Telescopio Solar McMath-Pierce en el Observatorio Nacional Kitt Peak (KPNO), un Programa de NOIRLab de NSF. El Telescopio Solar McMath-Pierce, situado a unos 88 kilómetros de Tucson (Arizona), vio su primera luz en 1962 y fue retirado de servicio en 2017 tras unos impresionantes 55 años de operación. Durante gran parte de su vida, fue el telescopio solar más grande de la Tierra y era único pues contaba con un gran espejo plano llamado heliostato que rastreaba el Sol a través del cielo y enviaba la luz solar hacia un túnel subterráneo, lugar donde se encontraba el telescopio. Este sistema ayudaba a minimizar las corrientes de aire caliente en la trayectoria de la luz hacia el telescopio, evitando así una degradación en la calidad de la imagen.
Aunque el Telescopio Solar McMath-Pierce está fuera de servicio, actualmente se encuentra en renovación para convertirse en el Centro de Divulgación Astronómica Windows on the Universe de NOIRLab. |
