X-rays and gamma-rays detected by these balloons are “secondary cosmic rays,” produced by the crash of primary cosmic rays into Earth’s upper atmosphere. They trace radiation percolating down toward our planet’s surface. The energy range of the sensors, 10 keV to 20 MeV, is similar to...
Prior to the discovery of cosmic rays, physicists believed that they were actually gamma rays being produced as a result of radioactive decay. It was only in the 1930s that a series of experiments proved that cosmic rays were mostly charged particles. Then, in 1954, the first substantial sam...
Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.
The synchrotron radiation isn't just seen in radio waves, if the electrons are accelerated to high enough speeds, emissions are also seen in infrared, optical, ultraviolet light, and even in X-ray radiation. The radio wave emissions of radio lobes can be so powerful they can give off as ...
What is the frequency of gamma rays? What is the frequency of radiation whose wavelength is 0.85 nm? How much nitrogen does a fiber laser use? A laser emits light at a wavelength of 630 \ nm. The power in the laser beam is 0.40 \ mW. How many photons pass per second in a cross-...
planet from harmful cosmic radiation and solar winds. The reason this field exists is the presence of iron surrounded by molten metal in the Earth’s core. As the Earth rotates and the core temperature changes, the molten metal on the outer core boils and churns, creating magnetic field ...
radiation lies on a spectrum, with lower-energy, longer-wavelength microwaves on one end, and higher-energy, shorter-wavelength Gamma rays on the other. The visible spectrum – that is, the electromagnetic wavelengths which are detectable by the human eye – lie somewhere ...
Fast radio bursts aren't the only powerful and mysterious energy blasts that puzzle astronomers. Gamma-ray bursts, first discovered in the 1960s, are some of the most powerful emissions in the universe. You can learn more about them onNASA's Hubblesite. The first FRB emerged from the Small...
