Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unprecedented energy of more than 10 tera-electronvolts. https://phys.org/news/2024-11-astronomers-cosmic-electrons-highest-energies.html Astronomy Mon, 25 Nov 2024 15:54:46 EST news651772478 Measurements by ESA's long-serving twin missions, Mars Express and Venus Express, have captured the dance between the intensity of high-energy cosmic rays and the influence of the sun's activity across our inner solar system. https://phys.org/news/2022-12-cosmic-ray-hidden-spacecraft-highlight.html Astronomy Mon, 05 Dec 2022 13:55:03 EST news589470901 Although no life has been detected on the Martian surface, a new study from astrophysicist and research scientist Dimitra Atri at the Center for Space Science at NYU Abu Dhabi finds that conditions below the surface could potentially support it. The subsurface—which is less harsh and has traces of water—has never been explored. According to Atri, the steady bombardment of penetrating galactic cosmic rays (GCRs) might provide the energy needed to catalyze organic activity there. https://phys.org/news/2020-07-astrophysicists-possibility-life-surface-mars.html Space Exploration Tue, 28 Jul 2020 07:33:34 EDT news515140407 In a small, square room walled by four feet of concrete, the air smells as if a lightning storm just passed through—crisp and acrid, like cleaning supplies. Outside, that's the smell of lightning ripping apart oxygen in the air, which readily reshuffles into ozone. But belowground in one of the rooms at NASA's Radiation Effects Facility, the smell of ozone lingers after high-energy radiation tests. The radiation that engineers use to test electronics for spaceflight is so powerful it shreds the oxygen in the room. https://phys.org/news/2019-06-nasa-spacecraft-harsh-space.html Space Exploration Tue, 11 Jun 2019 09:49:33 EDT news479465358 It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research from the University of New Hampshire's Space Science Center cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology. https://phys.org/news/2018-03-space-increasingly-hazardous.html Space Exploration Thu, 15 Mar 2018 09:37:36 EDT news440325445 On November 26, 2011, the Mars Science Laboratory began a 253-day, 560-million-kilometer journey to deliver the Curiosity rover to the Red Planet. En route, the Southwest Research Institute-led Radiation Assessment Detector (RAD) made detailed measurements of the energetic particle radiation environment inside the spacecraft, providing important insights for future human missions to Mars. https://phys.org/news/2013-05-exposure-journey-mars.html Space Exploration Thu, 30 May 2013 14:00:14 EDT news289120378 Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon's surface from galactic cosmic ray (GCR) bombardment that over time causes chemical changes in water ice and can create complex carbon chains similar to those that help form the foundations of biological structures. In addition, the radiation process causes the lunar soil, or regolith, to darken over time, which is important in understanding the geologic history of the moon. https://phys.org/news/2012-03-cosmic-rays-chemistry-lunar-ice.html Space Exploration Mon, 19 Mar 2012 13:51:52 EDT news251383901 The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. https://phys.org/news/2009-07-fossils-supermassive.html Astronomy Thu, 09 Jul 2009 17:20:03 EDT news166374804
