A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos.
Learn what gamma rays are, how they are produced, and how they are used. See examples of gamma rays on Earth and in space, and how they are detected and studied.
Gamma rays are hazardous to human lives. Due to their small wavelength, they can pass through detectors and mirrors. In this article, we discuss 15 uses of gamma rays. Properties of Gamma Rays Gamma rays are ionizing electromagnetic radiation that is obtained by the decay of the atomic nucleus. They are more penetrating.
Learn what gamma rays are, how they are produced, and where they are found in the universe. See images and links of gamma ray sources, such as pulsars, quasars, and gamma ray bursts.
The energy of gamma rays has a significant penetrating power because of its shortest wavelength. Materials with a high atomic number and high density have a greater ability to absorb gamma radiation. Shielding materials are generally measured based on the thickness required to halve radiation intensity.
Gamma rays, also known as gamma radiation, refer to electromagnetic radiation (no rest mass, no charge) of very high energies. Gamma rays are high-energy photons with very short wavelengths and thus very high frequency.
The electromagnetic spectrum is the range of all frequencies of electromagnetic radiation which includes visible light as well as invisible radiations like radio waves, infrared rays, gamma rays. Electromagnetic radiation from the spectrum has found multiple applications ranging from communication to manufacturing.
NASA's Fermi Gamma-ray Space Telescope has been mapping out the high-energy sky for several years. Here, Fermi scientists list 10 of their favorite gamma ray sources, from supernovas to black ...
Electromagnetic Radiation Examples
Gamma rays are like cheetahs: they are the charismatic megafauna of the particle world. They are light of the maximum possible potency, usually defined as a wavelength shorter than 10 –11 meter ...
Gamma rays are electromagnetic energy emitted by the nucleus of some radionuclides following radioactive decay.
Observations from high-flying aircraft revealed that thunderclouds act as natural particle accelerators, emitting energetic electromagnetic radiation more often than scientists expected.
All electromagnetic radiation travels as packets of energy call "photons". Gamma-ray photons have many properties similar to photons of visible light and radio waves: they travel in straight lines; they move at the speed of light; and they are not affected by magnetic or electric fields in space. However, there are also many differences between gamma-rays and other forms of energy. For example ...
In this article we will discuss the electromagnetic spectrum gamma rays, the examples, gamma rays uses and more.
Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
