Gamma Rays: The Most Powerful Form of Light

Gamma rays are the highest-energy form of light, with the shortest wavelengths on the spectrum.
They can pass through most materials, even several centimeters of solid lead.
Gamma rays come from nuclear reactions, radioactive decay, and cosmic events.
In space, gamma-ray bursts are the most powerful explosions ever observed.
The Sun also emits gamma rays during intense solar flares.
Doctors use controlled gamma rays in cancer therapy to target and destroy tumors.
Gamma rays are invisible, but detectors translate them into data and images.
Astronauts need protection from gamma radiation, which can damage cells and DNA.
The discovery of gamma rays in 1900 expanded our understanding of nuclear physics.
Studying cosmic gamma rays helps scientists probe black holes, neutron stars, and the early universe.
