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 […]

A new theoretical study has shown that Earth may be surrounded by long and very dense hair-like filaments of dark matter, which could potentially be directly observed by dedicated space-based dark matter detectors. Image Credit: NASA/JPL-Caltech
When hunting for dark matter, where would the best place to search for it be? The answer […]

By Leonidas Papadopoulos, on September 11th, 2015 An image of the galaxy EGS8p7, as seen from the Hubble Space Telescope. The top inset at the right shows a magnified view of the same image centered around EGS8p7, while the bottom insert shows the same view as seen by the Spitzer Space Telescope in infrared wavelengths. EGS8p7 is the most distant […]

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 May 2nd, 2015 The breathtaking image of the Hubble eXtreme Deep Field, which was created from data that had been collected with the Hubble Space Telescope in 2003 and 2004. In order for the image to be created, the space telescope pointed towards a small patch of the sky for a total of 50 days, while […]

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 […]
