Deep Space Images Shed More Light on Dark Matter

This map of dark matter was obtained from data from the KiDS survey, using ESO’s VLT Survey Telescope. It reveals an expansive web of dense (light) and empty (dark) regions. This image is one out of five patches of the sky observed by KiDS. The invisible dark matter is seen rendered in pink, covering an area of sky around 420 times the size of the full Moon. This image reconstruction was made by analyzing the light collected from over 3 million galaxies more than 6 billion light-years away. The observed galaxy images were warped by the gravitational pull of dark matter as the light traveled through the Universe. Some small dark regions, with sharp boundaries, appear in this image. They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in the map as no weak-lensing signal can be measured in these areas.

An international research team led by Dr. Massimo Viola from the Leiden Observatory and Dr. Hendrik Hildebrandt from the Argelander-Institut für Astronomie has gained fresh insight into the nature of dark matter. This map of dark matter was obtained from data from the KiDS survey, using ESO’s VLT Survey Telescope. It reveals an expansive web of dense (light) and empty (dark) regions.

Bathochordaeus charon and its ‘house’ in Monterey Bay: giant larvaceans use their oikoplastic cells to secrete complex filters or ‘houses’ that allow them to concentrate and feed on particles; a ‘house’ consists of a large, diaphanous outer structure as well as a smaller, more convoluted and bi-lobed inner structure that functions as a filter; together these serve to concentrate appropriately-sized food particles from the surrounding water; in situ, larvaceans in the genus Bathochordaeus are often visible from several meters away because their houses may span a meter in longest dimension.

Astronaut Bruce McCandless II, STS 41-B mission specialist, participates in a historical spacewalk. He is pictured a few meters away from the cabin of the Earth-orbiting Space Shuttle Challenger. This spacewalk represented the first use of a nitrogen-propelled, hand-controlled device called the Manned Maneuvering Unit (MMU), which allows for much greater mobility than that afforded previous space walkers who had to use restrictive tethers.

This artist’s view shows how the light coming from the surface of a strongly magnetic neutron star (left) becomes linearly polarized as it travels through the vacuum of space close to the star on its way to the observer on Earth (right). The polarization of the observed light in the extremely strong magnetic field suggests that the empty space around the neutron star is subject to a quantum effect known as vacuum birefringence. The magnetic and electric field directions of the light rays are shown by the red and blue lines. Image credit: L. Calçada / ESO.
