The story begins four years ago when Schwadron and colleagues first sounded the alarm about cosmic rays. Analyzing data from the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument onboard NASA’s Lunar Reconnaissance Orbiter (LRO), they found that cosmic rays in the Earth-Moo...
Galactic cosmic rays comprise a mixture of highly energetic protons, helium ions, and higher charge and energy ions ranging from lithium to iron, and they are extremely difficult to shield against. These ions interact with spacecraft materials and human tissues to create a complex mixed ...
Cosmic rays are accelerated charged particles – mostly protons and atomic nuclei. The rarest and most energetic particles, called UHECRs (ultrahigh-energy cosmic rays), carry more than a billion times the energy of 3 GeV gamma rays, and their origins remain one of the biggest mysteries in ast...
— Pulsar surprises astronomers with record-breaking gamma-rays — New kind of pulsar may explain how mysterious 'black widow' systems evolve The researchers' next step will be to turn to the wider astronomical community and build on this impressive GRB catalog. To that end, they have made the...
These cosmic rays don’t just hit people, but things in space, too, and sometimes cause problems. Pettit wrote: “Free from the protection offered by the atmosphere, cosmic rays bombard us within Space Station, penetrating the hull almost as if it was not there. They zap everything inside...
"The charged particles producing the X-rays travel along the magnetic field, determining the basic shape of the nebula, like the bones do in a person's hand." An X-ray image and infrared data show the "ghostly cosmic hand." NASA Researchers said that in the nebula, there is a ...
The source of cosmic rays, a universe mystery that has long perplexed astronomers, has just gotten stranger. Scientists have nearly ruled out their prime suspect, gamma-ray bursts.
