Radiation on Europa dictates where search for life begins
... the building blocks for proteins and they also serve as a useful example of molecular survival in high radiation environments. "The radiation that bombards Europa's surface leaves a fingerprint," said Kevin Hand, co-author of the new research and...

High-energy theory models questioned as neutron star produces most energetic pulsed emission radiation ever detected
...observed in 2011 by the Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) observatory and the Very Energetic Radiation Imaging Telescope Array System (VERTIAS), when at the time, researchers unexpectedly observed a burst of very energetic photons...

Electric orbit raising and space weather
...mission, the potential impact of a storm like the March 1991 event can be evaluated in terms of the associated radiation damage and solar cell degradation. Figure 2. Degradation of EOR-1’s solar panels (blue) increased from ~3% in a quiet environment...

How to grow plants in a spacecraft
... in space. Growing plants in a spacecraft Space presents two major sources of stress for plants: cosmic radiation and microgravity. Radiation affects plant growth negatively and increases the risks of genetic mutations, so protecting plants from...
