Revealing the magnetic universe
... counterbalanced by the unexpectedly high interstellar magnetic fields and stellar winds as well as much higher fluxes of galactic cosmic rays. The region just outside the heliopause, known as the heliosheath, is where the magnetic fields and stellar...

Developing Mars
... the liberating possibility of an ‘unlimited Mars career’ Crewed flights, which have a further need for shielding against cosmic rays, would also benefit from Omaha Trail systems at Deimos. While 40 cm of water gives effective shielding, the water...

Spaceflight and the radiation problem
...Van Allen radiation belts. Earth’s magnetic field and atmosphere protect us from the constant bombardment of galactic cosmic rays – energetic particles that travel at close to the speed of light and penetrate the human body. An astronaut on a mission...

Pregnancy among the stars - the biology of birth beyond Earth
... containing chromosomes, being roughly 10 times larger, and therefore they present a much larger target for galactic cosmic rays. Holden argues that radiation-induced mutations may therefore occur more frequently in maternal genetic material than...

Astronomers using GBT discover previously unknown huge galactic structure
...-up observations revealed a large, faint, broad feature in the entire line of sight – a possible home of the mysterious cosmic rays rays discovered earlier. To rule out the possibility that this feature could be an instrumental by-product of the GBT...
