The GRANTECAN discovers the largest cluster of galaxies known in the early universe
A study, led by researchers at the Instituto de Astrofísica de Canarias (IAC) and carried out with OSIRIS, an instrument on the Gran Telescopio Canarias (GTC), has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years from us, will have evolved…
Water worlds may be abundant in our galaxy
A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Mlilky Way. Source: https://earthsky.org/space/water-common-on-planets-pebble-accretion-milky-way…
People sleep less before a full moon
Researchers find that whether you live in a rural or urban environment, your sleep patterns are affected by the full moon. On the nights leading up to full moon, people fall asleep later and sleep less overall. Source: https://earthsky.org/human-world/people-sleep-less-before-full-moon…
Researchers discover mechanism behind influence of irradiation defects on tritium permeation barrier
Recently, researchers led by Prof. Zhou Haishan from the Institute of Plasma Physics (ASIPP) of the Hefei Institutes of Physical Science (HFIPS) reported their new findings about the influence of irradiation effects on hydrogen permeation through alpha-alumina (α-Al2O3) tritium permeation barrier (TPB). …
Astrophysicists design ‘radically different’ world map
You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round. Source: https://earthsky.org/earth/astrophysicists-new-design-world-map…
Merging boson stars could explain massive black hole collision and prove existence of dark matter
An international team of scientists led by the Galician Institute of High Energy Physics (IGFAE) and the University of Aveiro shows that the heaviest black hole collision ever observed, produced by the gravitational-wave GW190521, might actually be something even more mysterious: the merger of two boson stars. This would be the first evidence of the existence of these hypothetical objects, which…
