A composite image of a galaxy as seen in different wavelengths by the GAMA survey. The results of the survey, which studied more than 200,000 galaxies in the local Universe, revealed that the latter's total energy output has decreased by at least 50 percent during the last 2 billion years.

{"Image ImageDescription": "This composite picture shows how a typical galaxy appears at different wavelengths in the GAMA survey. This huge project has measured the energy output of more than 200 000 galaxies and represents the most comprehensive assessment of the energy output of the nearby Universe. The results confirm that the energy produced in a section of the Universe today is only about half what it was two billion years ago and find that this fading is occurring across all wavelengths from the ultraviolet to the far infrared.", "Image Software": "Adobe Photoshop CC 2015 (Windows)"}
