NGC 6914 lies 6,000 light-years away in Cygnus and is a very rare region in which one can see all three classes of nebulae, red emission, blue reflection, and dark obscuring, within a very small expanse of sky. The broad expanse of hydrogen gas is re-emitting red hydrogen alpha light as a result of ionization from the ultraviolet light from several hot stars of the Cygnus OB2 association. These stars also illuminate the blue reflection nebulae of residual dust from their formation. The entire tableau silhouettes numerous dark nebulae also being sculpted by the stellar winds emitted by these stars.

An odd couple lives some 100 million light years away. Here we find a spiral galaxy, NGC 2276 on the top, and its neighbor NGC 2300 on the bottom. Space scientists conducting a study of ultraluminous x-ray sources (ULXs) looking for intermediate-mass black holes using NASA’s Chandra X-ray Observatory believe they have found a candidate. An interesting object, called NGC 2276-3c, located in an arm of spiral galaxy NGC 2276, appears to have the right characteristics.

Περιοχή γύρω από τον αστέρα Sadr στον αστερισμό του Κύκνου. Μια από τις πιο όμορφες περιοχές του ουρανού για αστροφωτογράφιση. Παραθέτω το νέο αποτέλεσμα ύστερα απο χρήση μιας πιο ολοκληρωμένης επεξεργασίας. Οι λήψεις έγιναν από το σκοτεινό ουρανό του χωριού.
