For the first time, astrophysicists have used artificial intelligence techniques to generate complex 3D simulations of the universe. The results are so fast, accurate and robust that even the creators aren't sure how it all works. The Deep Density Displacement Model can accurately simulate how the cosmos would look if certain parameters were tweaked -- such as the dark matter composition of the universe -- even though the model never received training data where those parameters varied.
One-seventh of the world's population depends on rivers flowing from Asia's high mountain ranges for water to drink and to irrigate crops. Rapid changes in the region's climate are likely to influence food and water security in India, Pakistan, China and other nations. NASA keeps a space-based eye on changes like these worldwide to better understand the future of our planet's water cycle.
Together with Germany's National Meteorological Service, the Deutscher Wetterdienst, computer science professor Jens Dittrich and his doctoral student Christian Schön from Saarland University are working on a system that is supposed to predict local thunderstorms more precisely than before.
Researchers using ALMA (Atacama Large Millimeter/submillimeter Array) found a small dust concentration in the disk around TW Hydrae, the nearest young star. It is highly possible that a planet is growing or about to be formed in this concentration. This is the first time that the exact place where cold materials are forming the seed of a planet has been pinpointed in the disk around a young star.
Compounds containing iron, cyanide, and carbon monoxide discovered in carbon-rich meteorites by a team of scientists at Boise State University and NASA may have helped power life on early Earth.
Scientists using NASA's Hubble Space Telescope have confirmed the presence of electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the interstellar medium (ISM) -- the gas and dust that fills interstellar space.
A Southwest Research Institute-led team studied the orientation of distant solar system bodies to bolster the 'streaming instability' theory of planet formation.
Inspired by movie streaming services such as Netflix or Hulu, a Southwest Research Institute scientist developed a technique to look for stars likely to host giant, Jupiter-sized planets outside of our solar system. She developed an algorithm to identify stars likely to host giant exoplanets, based on the composition of stars known to have planets.
Researchers have shown for the first time that these insects use different directional sensors to achieve the highest possible navigational precision in different conditions.
One of the great attractions of the island of Santorini, in Greece, lies in its spectacular volcanic landscape, which also contains places similar to those of Mars. A team of European and U.S. scientists has discovered it after analysing basaltic rocks collected in one of its coves.
