redOrbit Staff & Wire Reports - Your Universe Online A distant quasar discovered by astronomers working at Hawaii’s WM Keck Observatory has for the first time revealed part of the filament networks believed to connect galaxies in a cosmic web, according to research published Sunday in the journal Nature. Using the observatory’s 10-meter Keck I Telescope, a team of researchers including first author Sebastiano Cantalupo, a postdoctoral fellow at the University of California,...

April Flowers for redOrbit.com - Your Universe Online A giant filament of dark matter extends 60 million light-years from one of the most massive galaxy clusters known. Leftover from the very first moments after the Big Bang, the filament is part of the cosmic web that constitutes the structure of the Universe. Scientists using the NASA/ESA Hubble Space Telescope have studied this filament in 3D for the first time and conclude that if the filament is representative of the rest of the...

Astronomers have tracked down a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us. The discovery, made possible by combining two of the most powerful ground-based telescopes in the world, is the first observation of such a prominent galaxy structure in the distant Universe, providing further insight into the cosmic web and how it formed. "Matter is not distributed uniformly in the Universe," says Masayuki Tanaka from ESO, who led the new...

ESA's orbiting X-ray observatory XMM-Newton has been used by a team of international astronomers to uncover part of the missing matter in the universe.10 years ago, scientists predicted that about half of the missing "Ëœordinary' or normal matter made of atoms exists in the form of low-density gas, filling vast spaces between galaxies.All the matter in the universe is distributed in a web-like structure. At dense nodes of the cosmic web are clusters of galaxies, the largest objects...

Our universe is a mess — a colossal "cosmic web" of galaxies strung into filaments and tendrils that are millions or billions of light-years long. Although this web's basic structure is resolved, astronomers say understanding it in more detail requires new observatories, better computing and a lot of luck. "When you look into a large telescope, the reality of the cosmic web hits you in the face because you can see how galaxies are organized," said Rodrigo Ibata, an...

Chandra -- NASA's Chandra X-ray Observatory has discovered two huge intergalactic clouds of diffuse hot gas. These clouds are the best evidence yet that a vast cosmic web of hot gas contains the long-sought missing matter - about half of the atoms and ions in the Universe. Various measurements give a good estimate of the mass-density of the baryons - the neutrons and protons that make up the nuclei of atoms and ions - in the Universe 10 billion years ago. However, sometime during the last 10...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
