An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion.
The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left.

Galaxies of the NGC 7771 Group are featured in this intriguing skyscape. Some 200 million light-years distant toward the constellation Pegasus, NGC 7771 is the large, edge-on spiral near center, about 75,000 light-years across, with two smaller galaxies just below it. Large spiral NGC 7769 is seen face-on to the right. Galaxies of the NGC 7771 group are interacting, making repeated close passages that will ultimately result in galaxy-galaxy mergers on a cosmic timescale.
Nasa’s new planet-hunting telescope has discovered its first five worlds beyond our Solar System.
Numerous planets have been found before by other telescopes, such as Hubble, but the sole mission of the Kepler observatory – launched last year – has been to find potential ‘Earths’ elsewhere in our galaxy.
Unfortunately life is unlikely to survive on the new planets as they are thought to generate hellish heat. Estimated temperatures of the worlds range from 1,200 to 1,650 degrees Celsius, hotter than molten lava.
