The modules that the major space agencies plan to erect on the Moon could incorporate an element contributed by the human colonizers themselves: the urea in their pee. European researchers have found that it could be used as a plasticizer in the concrete of the structures.
Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing at the center of the host galaxy. This result will cast light on the mystery of the evolutionary process of galaxies in the early Universe.
Cornell University astronomers have created five models representing key points from our planet's evolution, like chemical snapshots through Earth's own geologic epochs. The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for Earth-like planets in distant solar systems.
The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.
A holographic cosmological model with a power-law term has been proposed by a Kanazawa University researcher to study thermodynamic properties on the horizon of the Universe. This model was found to satisfy the second law of thermodynamics. In addition, a relaxation-like process of the Universe was examined systematically to study maximization of the entropy on the horizon.
A new study by scientists at Lawrence Berkeley National Laboratory, UC Berkeley, and the University of Michigan -- published today in the journal Science - concludes that a possible dark matter-related explanation for a mysterious light signature in space is largely ruled out.
Head congestion is one of the most common symptoms experienced by astronauts during spaceflight. This observational study examined preflight and postflight head magnetic resonance images (MRIs) of 35 astronauts who participated in either a short-duration (30 days or less) Space Shuttle mission or a long-duration (greater than 30 days) International Space Station mission.
An unidentified X-ray signature recently observed in nearby galaxies and galaxy clusters is not due to decay of dark matter, researchers report.
Eighty-five percent of the universe is composed of dark matter, but we don't know what, exactly, it is.
Almost 35 years ago, scientists made the then-radical proposal that colossal hydrogen bombs called novae go through a very long-term life cycle after erupting, fading to obscurity for hundreds of thousands of years and then building up to become full-fledged novae once more. A new study confirms that the novae we observe flashing throughout the universe represent just a few percent of these cataclysmic variables, as they are known, with the rest "hiding" in hibernation.
