Del

Hot blue star

Its story

Delta Tucanae flares 251 light-years away in Tucana, a southern constellation drawn up by Bayer from the catalogues of Keyser and de Houtman. A hot blue-white B-type star, it is a celestial neighbour of the Small Magellanic Cloud and of the globular cluster 47 Tucanae. Its light accompanies one of the most beautiful tableaux of the southern firmament —where satellite galaxy and cluster meet within a single glance.
