NGC 55
Composición RGB generada de forma determinista con 000 → rojo, 001 → verde y 002 → azul. La banda adicional se conserva por separado.
Cambia entre RGB y cada filtro para comparar lo que registró el sensor. Los FITS originales permanecen intactos.
Sobre esta observación
NGC 55 es una galaxia del Grupo de Sculptor situada a unos 6,5 millones de años luz. La vemos casi de canto, por eso aparece como una franja alargada y algo irregular, con zonas brillantes donde todavía están naciendo nuevas estrellas.
Por su forma y estructura se parece bastante a la Gran Nube de Magallanes, aunque NGC 55 es mucho más lejana y se extiende a lo largo de decenas de miles de años luz. Las bandas oscuras que atraviesan algunas regiones son grandes concentraciones de polvo interestelar.
Curiosidad: fue descubierta en 1826 por el astrónomo escocés James Dunlop desde Australia, y bajo cielos muy oscuros puede llegar a observarse incluso con prismáticos.
