This artist’s conception illustrates one of the most primitive supermassive black holes known (central black dot) at the core of a young, star-rich galaxy. Astronomers using NASA’s Spitzer Space Telescope have uncovered two of these early objects, dating back to about 13 billion years ago. The monstrous black holes are among the most distant known, and appear to be in the very earliest stages of formation, earlier than any observed so far. Credit: NASA/JPL-Caltech.

A star at sea

Oleg Bouevitch from Nepean, Ontario, Canada

The 2nd-magnitude star Sadr (Gamma [γ] Cygni; at right) lies awash in a sea of glowing gas and dark tendrils of dust. The most prominent dark nebula, at lower left, is cataloged as LDN 889, splitting the bright nebulae LBN 245 (far lower left) and LBN 249 (center). This imager took Hα/OIII/SII exposures of 3, 13, and 9 hours, respectively, with a 10-inch f/4.6 scope.
