An artist’s concept of the Wide Field Infrared Survey Telescope (WFIRST). NASA has officially chosen the infrared-space telescope as the scientific successor to the James Webb Space Telescope, with a projected launch date around the 2024 timeframe. WFIRST is expected to make significant contributions in the study of dark energy and the characterisation […]

By Leonidas Papadopoulos, on August 19th, 2015 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.

By Leonidas Papadopoulos, on February 28th, 2015 A view of the Milky Way galaxy in visible wavelengths. Two recent studies have provided more evidence which indicate that our galaxy is dominated in dark matter. In the image, the blue and red dots pinpoint the rotation curve tracers that were used in one of the studies and were colour-coded according to […]

By Leonidas Papadopoulos, on January 6th, 2015 A composite, multi-wavelength image of the young galaxy cluster XDCP J0044.0-2033, also known as the Gioiello Cluster, which is located 9.6 billion light-years away. In the image, X-ray wavelengths appear purple, infrared appear as large red halos around some galaxies, and visible light appears as are red, green, and blue. Image Credit: X-ray: […]
