He concluded that the radiation must be coming from above the atmosphere. For this, he was awarded the Nobel Prize in 1936. The name “cosmic ray” itself dates to 1925, when Nobel laureate and former ...

The Astrophysics of Cosmic Rays These energetic particles have come to be regarded (along with the stars, planets, gas and dust and electromagnetic radiation) as one of the main Components of the ...

Stars like the Sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion ...

BL Lacertae, an enigmatic blazar, has shattered long-held classification norms, leaving astronomers baffled. Originally ...

Called electromagnetic radiation, such waves travel at the speed of light and bring us almost all the information we have about the universe. Gamma rays are much shorter in wavelength than visible ...

Primary among non-fictional cosmic gamma-ray sources ... This includes X-rays and the highest frequency electromagnetic radiation, gamma rays, which have wavelengths that are billions of times ...

Radiation hardened devices are built to withstand cosmic rays and other natural electromagnetic radiation, as well as nuclear explosions. The effects of such radiation can be a temporary ...

The radiation we receive from outer space is called cosmic radiation or cosmic rays. We also receive exposure from man-made radiation, such as X-rays, radiation used to diagnose diseases and for ...

This is because the electromagnetic radiation produced by blazars extends from the radio range through the optical, ultraviolet and X-ray regions to gamma radiation of the highest energies.

This is because the electromagnetic radiation produced by blazars extends from the radio range through the optical, ultraviolet and X-ray regions to gamma radiation of the highest energies.

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
