Conditions inside the Shiveluch volcano include roughly 10%-14% water by weight (wt%), according to research from Washington University in St. Louis. Most volcanoes have less than 1% water. For subduction zone volcanoes, the average is usually 4%, rarely exceeding 8 wt%, which is considered superhydrous.
A new international study led by astrophysicist Eric Agol from the University of Washington has measured the densities of the seven planets of the exoplanetary system TRAPPIST-1 with extreme precision, the values obtained indicating very similar compositions for all the planets. This fact makes the system even more remarkable and helps to better understand the nature of these fascinating worlds. This study has just been published in the Planetary Science Journal.
in a new study published in The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and areas of abundant ionised particles in the hot outer atmosphere.
Scientists from Australia have set a world record for the most stable transmission of a laser signal through the atmosphere. The team combined Aussie 'phase stabilisation' technology with advanced self-guiding optical terminals to 'effectively eliminate atmospheric turbulence,' an advance which could help test Einstein's theory of general relativity.
Astronomers at the Center for Astrophysics | Harvard & Smithsonian have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. The findings were published this month in the Astrophysical Journal Letters.
A new collaborative study from researchers at the Geisel School of Medicine at Dartmouth and the University of Washington and published in the Proceedings of the National Academy of Sciences (PNAS), reveals unexpected insights into how skin exposure to ultraviolet light can worsen clinical symptoms in autoimmune diseases such as lupus.
Scientists from an international collaboration have found evidence of alpha particles at the surface of neutron-rich heavy nuclei, providing new insights into the structure of neutron stars, as well as the process of alpha decay.
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. The study has implications for signs of potential habitability of exoplanets.
An MIT-led search for axions from nearby star Betelgeuse has come up empty, significantly narrowing the search for hypothetical dark matter particle.
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.
