Electro Magnetic Spectrum
The electromagnetic (EM) spectrum is the range of all types of EM radiation . Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves , infrared light , ultraviolet light , X-rays and gamma-rays .
Cherenkov light Detectors
Long before experiments could detect gamma-rays emitted by cosmic sources, scientists had known that the Universe should be producing such high energy photons .
Oct. 6, 2011 — A thousand years ago, a brilliant beacon of light blazed in the sky, shining brightly enough to be seen even in daytime for almost a month.
Tycho’s star lives on in gamma rays DR EMILY BALDWIN ASTRONOMY NOW Posted: 14 December 2011 Using the Fermi Gamma-Ray Space Telescope, astronomers have found that the shattered remains of the 1572 supernova event known as ‘Tycho’s supernova’ live on in high-energy gamma rays, providing vital insight into the generation of cosmic rays.
