Over the coming weeks we will feature, in no particular order, each of the final 16 selected images and winners will be announced by Royal Museums Greenwich on 17 September. The winning images are to be showcased at the Royal Observatory Greenwich in an exhibition opening 18 September.
A spectacular new image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the galactic plane visible from the Southern Hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves.
A strange new kind of galactic beast has been spotted in the cosmic wilderness. Dubbed “super spirals,” these unprecedented galaxies dwarf our own spiral galaxy, the Milky Way, and compete in size and brightness with the largest galaxies in the universe. The galaxies have long hidden in plain sight by mimicking the appearance of typical spirals.
Using the advanced adaptive optics system GeMS, on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box — a tightly packed cluster of stars that is one of the few places in our galaxy where astronomers think stars can actually collide.
