English: This image is so beautiful that it could almost be a painting, but it is real. It has been produced using observations made at the SMARTS 0.9-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), which is a Program of NSF’s NOIRLab. It features a reflection nebula known as NGC 2626, which lies 3300 light-years from Earth.
Reflection nebulae are not luminous themselves, but they reflect light from a nearby star or stars. The light scatters off the dust particles in the nebulae, which often results in reflection nebulae having a blue tint, because blue light scatters more efficiently. This is the same phenomenon that makes the sky on Earth appear blue — the laws of physics are the same throughout our Universe! The red nebulosities are glowing hydrogen gas.
Español: Esta imagen es tan bella que casi podría tratarse de una pintura, pero es real. Se generó a partir de las observaciones del Telescopio SMARTS de 0,9 metros en Cerro Tololo (CTIO), un Programa de NOIRLab de NSF y representa una nebulosa de reflexión conocida como NGC 2626 que se encuentra a 3.300 años luz de la Tierra.
Las nebulosas de reflexión no son luminosas, sino que reflejan la luz de una o varias estrellas cercanas. Esta luz se dispersa en las partículas de polvo que contienen, lo que a menudo hace que las nebulosas de reflexión tengan un tinte azul, pues este color de la luz se dispersa de forma más eficiente. Este es el mismo fenómeno que hace que el cielo en la Tierra se vea de color azul. ¡Las leyes de la física son las mismas en todo nuestro Universo! Las zonas de color rojo son áreas de gas de hidrógeno incandescente. |
