As Curiosity rover marches across Mars, the red planet's watery past comes into clearer focus.
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.
An international team of astronomers has revealed the 'DNA' of more than 350,000 stars in the Milky Way, which should help them find the siblings of the sun, now scattered across the sky. This is the first major announcement of an ambitious survey as part of a quest to uncover the formulation and evolution of galaxies -- after the Australian-led Galactic Archaeology survey, called GALAH, commenced three years ago.
Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging mission. The origin of energetic electrons detected in Mercury's magnetic tail has puzzled scientists. This new study, appearing in Physics of Plasmas, provides a possible solution to how these energetic electrons form.
UCSB physicists team up with Caltech astronomers to commission the most advanced camera in the world.
Planets orbiting 'short-period' binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars' evolution, according to new research from the University of Washington.
With an instrument at the Very Large Telescope in Chile scientists of ETH Zurich observed planet-forming disks around young stars similar to the sun 4,5 billion years ago. Surprisingly, the disks are very different. The data will help to shed more light on the formation processes of planets.
Legendary explorers and visionaries, real and fictitious, are among those immortalized by the IAU in the first set of official surface-feature names for Pluto's largest moon, Charon. The names were proposed by the New Horizons team and approved by IAU Working Group for Planetary System Nomenclature.
Researchers from the University of Texas Institute for Geophysics (UTIG) have helped discover the first subglacial lakes ever found in the Canadian High Arctic.
A well-known experiment with young people bouncing a ball showed that when an observer focuses on counting the passes, he does not detect if someone crosses the stage disguised as a gorilla. According to researchers at the University of Cádiz (Spain), something similar could be happening to us when we try to discover intelligent non-earthly signals, which perhaps manifest themselves in dimensions that escape our perception, such as the unknown dark matter and energy.
