Descripci\u00f3n<\/h3>\n\n\n\n

Espa\u00f1ol:<\/strong> M51 se localiza a poco m\u00e1s de 2\u00ba de Al Kaid (Eta <\u03b7> Ursa Majoris), la estrella que marca la punta de la cola de la Osa. Esta galaxia forma un par con NGC 5195, una diminuta galaxia a s\u00f3lo varios arcos de minuto del centro de M51 (sobre la galaxia principal, en el dibujo). Ambas son f\u00e1ciles de observar en el telescopio de 6 pulgadas (15 cm.), a cualquier aumento. Aunque suficientemente brillante, los brazos espirales no eran visibles. En telescopios de m\u00e1s de 8 pulgadas (~20cm) de apertura, se puede pareciar el puente de material que une a ambas y los brazos espirales de M51.<\/p>\n\n\n\n

English:<\/strong> M51 is located just over 2\u00ba from Al Kaid (Eta <\u03b7> Ursa Majoris), the star that marks the tip of the Great Bear’s tail. This galaxy forms a pair with NGC 5195, a tiny galaxy just several arcminutes from the center of M51 (above the main galaxy, according to the sketch). Both are easy to observe in a 6-inch (15 cm) telescope, at any magnification. Although it’s bright enough, the spiral arms were not visible. In telescopes 8 inches aperture and larger, the bridge of material that joins both galaxies and the spiral arms of M51 can be seen.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong>  Nebulosa bien d\u00e9bil, sin estrellas, cerca de la oreja de los Galgos, el m\u00e1s septentrional, debajo de la estrella \u03b7 de 2.da<\/sup> magnitud de la cola de la gran Osa: M. Messier descubri\u00f3 esta nebulosa el 13 de octubre de 1773, observando el cometa que apareci\u00f3 ese a\u00f1o. Solo se puede ver dif\u00edcilmente con un anteojo ordinario de 3 pies \u00bd: cerca de ella hay una estrella de la 8.va<\/sup> magnitud. M. Messier report\u00f3 su posici\u00f3n en la carta del cometa observado en 1773 & 1774. Memorias de la Academia 1774, l\u00e1mina 111. <\/em>Es doble, teniendo cada una un centro brillante, alejado un del otro de 4\u2032 35\u2033. Las dos atm\u00f3sferas de tocan. Una es m\u00e1s d\u00e9bil que la otra. Vuelta a ver muchas veces. <\/p>\n\n\n\n
