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

Espa\u00f1ol:<\/strong> El dibujo muestra el “coraz\u00f3n” del c\u00famulo de galaxias de Virgo. M84 es la galaxia que se ve al lado inferior izquierdo del dibujo. Su forma es pr\u00e1cticamente redonda y su centro es m\u00e1s brillante que el de sus compa\u00f1eras. Esta es una galaxia el\u00edptica de magnitud 9.1. Al centro del dibujo se puede apreciar a M86, tambi\u00e9n una galaxia el\u00edptica. Las dem\u00e1s galaxias que se presentan en el dibujo no pertenecen al cat\u00e1logo de Messier. Seg\u00fan la orientaci\u00f3n del dibujo, estas son: al lado derecho, en l\u00ednea con M84 y M86, NGC 4438 y NGC 4435, un par de galaxias que por su semejanza en brillo y tama\u00f1o han recibido el nombre de “Los Ojos”; ninguna de las dos exhibe un centro distinguible en el telescopio de 6 pulgadas (15.4 cm). La m\u00e1s grande, NGC 4438, es una galaxia espiral S0 peculiar de magnitud 10.2, mientras que NGC 4435 es una espiral barrada SB0 de magnitud 10.8. Formando un tri\u00e1ngulo equil\u00e1tero con M84 y M86 est\u00e1 NGC 4388, una galaxia espiral Sb alargada de magnitud 11.0. En el centro de este tri\u00e1ngulo est\u00e1 NGC 4387, una tenue galaxia el\u00edptica de magnitud 12.1. Las restantes dos galaxias que se aprecian son NGC 4413 y NGC 4425: la primera est\u00e1 clasificada como SBab, y tiene una magnitud de 12.2; la otra, ligeramente alargada, est\u00e1 clasificada como SB0, y tiene una magnitud de 11.8. Dentro de este mismo campo de visi\u00f3n debe encontrarse NGC 4402, pero no la pude ver.<\/p>\n\n\n\n

English:<\/strong> The sketch shows the “heart” of the Virgo galaxy cluster. M84 is the galaxy seen on the lower left side. Its shape is practically round and its center is brighter than that of its companions. This is an elliptical galaxy of magnitude 9.1. M86, also an elliptical galaxy, is at the center. The other galaxies included in the sketch do not belong to the Messier catalog. According to the sketch\u2019s orientation, these are: on the right side, in a line with M84 and M86, are NGC 4438 and NGC 4435, a pair of galaxies that have been nicknamed “The Eyes” because of their similar size and brightness; neither of them exhibits a distinguishable center on the 6-inch (15.4 cm) telescope. The largest, NGC 4438, is a (once classified as a) peculiar spiral galaxy of magnitude 10.2, while NGC 4435 is an elliptical galaxy of magnitude 10.8. Forming an equilateral triangle with M84 and M86 is NGC 4388, an elongated spiral galaxy of 11.0 magnitude. In the center of this triangle lies NGC 4387, a faint elliptical galaxy of magnitude 12.1. The remaining two galaxies are NGC 4413 and NGC 4425: the first is classified as SBab, and has a magnitude of 12.2; the other, slightly elongated, is classified as SB0, and has a magnitude of 11.8. NGC 4402 must be within this same field of view, but I couldn\u2019t see it.<\/p>\n\n\n\n
