Latest Galactic cosmic ray Stories
Streaming across the Universe are high-energy charged particles, known as cosmic rays. For more than their origins have remained a mystery.
A new study reports that data collected by NASA's Lunar Reconnaissance Orbiter (LRO) reveals that lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel.
There are many barriers that stand in the way of sending a human team to the surface of Mars. But near the top of the list of dangers would have to be the radiation exposure during the round trip voyage through the solar system. Clearly, a detailed understanding of the exposure levels is key in planning any mission to the Red Planet.
In a paper to be published in the April 10, 2011, issue of The Astrophysical Journal, scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including lead author Nathan Schwadron and others from the University of New Hampshire, isolate and resolve the mysterious "ribbon" of energy and particles the spacecraft discovered in the heliosphere â€“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays.
In the paper the authors from the Key Laboratory of Particle Astrophysics, Institute of High Energy Physics, Chinese Academy of Sciences in Beijing proposed a new model trying to explain the knee at cosmic ray spectra.
NASA's current mission in orbit around the moon, the Lunar Reconnaissance Orbiter, or LRO, has been providing crucial insights about our nearest celestial neighbor since its launch in June.
GREENBELT, Md., Dec. 15 /PRNewswire-USNewswire/ -- NASA's current mission in orbit around the moon, the Lunar Reconnaissance Orbiter, or LRO, has been providing crucial insights about our nearest celestial neighbor since its launch in June.
Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA's ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high.
Thanks to a unique "ballistic study" that combines data from ESO's Very Large Telescope and NASA's Chandra X-ray Observatory, astronomers have now solved a long-standing mystery of the Milky Wayâ€™s particle accelerators.
An international team of researchers has discovered a puzzling surplus of high-energy electrons bombarding Earth from space.
Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
