Scientists Deduce Contents Of Cosmic Mystery Box
2013-01-01 10:16:02

April Flowers for redOrbit.com - Your Universe Online Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box. Scientists who are trying to understand why tiny particles rain down from space face a similar dilemma, but on a much grander scale. Their mystery box is a hundred thousand light years across, and the only clues...

2013-01-01 05:21:42

April Flowers for redOrbit.com - Your Universe Online Space travel is fraught with dangers for astronauts and equipment alike. A new study, led by the University of Rochester Medical Center, reveals that it may be much more dangerous than previously thought. The findings, published in the journal PLOS ONE, show that cosmic radiation — which would bombard astronauts on deep space missions — could accelerate the onset of Alzheimer's disease. "Galactic cosmic radiation poses a...

2012-12-28 11:30:22

Lawrence LeBlond for redOrbit.com - Your Universe Online A new study published this week in the Journal of the National Cancer Institute has found that an expensive prostate cancer radiation treatment provided no long-term benefit over traditional radiation. The treatment, known as proton beam therapy, uses atomic particles to treat cancer and is said to target tumors more precisely than traditional methods. However the method has been found to produce no fewer side effects than much...

[ Watch the Video: Solar Eruption in Full HD ] redOrbit Staff & Wire Reports - Your Universe Online During his trip to the International Space Station (ISS), Canadian astronaut Chris Hadfield carried with him a new set of instruments designed to help measure the amount of radiation an astronaut absorbs during a typical trip into space. The radiation measured by the devices is called neutron radiation. It is one of the more dangerous types officials from the Canadian Space Agency...

Nuclear Fallout
2013-04-01 10:26:30

Nuclear fallout, or just simply fallout, known also as Black Rain, is the residual radioactive material that is propelled into the upper atmosphere after a nuclear black or a nuclear reaction that is conducted in an unshielded facility. It is so called because it "fall out" of the sky after the explosion and the shock wave have passed. It most commonly refers to the radioactive dust and ash that is created when a nuclear weapon explodes, but such dust can also come from a damaged nuclear...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
