Summary
| Description |
English: Sextans B is an irregular dwarf galaxy, meaning that it is irregularly shaped and smaller than our galaxy, the Milky Way. It lies around 4.5 million light-years from Earth and is located in the constellation Sextans in the southern sky. Captured with the Nicholas U. Mayall 4-meter Telescope, this image of Sextans B features red-colored star-forming regions near the galaxy’s center. Surrounding the galaxy are several bright stars that are located much closer to us in our galaxy, identified by the crisscross patterns created by light interacting with the structure of the telescope, as well as numerous fuzzy-looking background galaxies that appear small because theyare much farther away than Sextans B.
Español: Sextans B es una galaxia enana irregular, lo que significa que tiene una forma irregular y es más pequeña que nuestra galaxia, la Vía Láctea. Está ubicada a unos 4,5 millones de años luz de la Tierra, en la constelación del Sextante en el cielo del hemisferio Sur. Esta imagen, obtenida en el Telescopio Nicholas U. Mayall de 4 metros, destaca regiones de formación estelar de color rojo cerca del centro de la galaxia. Alrededor de la misma, hay diversas estrellas brillantes que están ubicadas mucho más cerca, en nuestra propia galaxia, y que pueden ser distinguidas como aquellas que muestran patrones entrecruzados que son creador por la interacción de la luz con la estructura del telescopio, así como galaxias de fondo borrosas que se ven muy pequeñas debido a que están mucho más lejos que Sextans B |
