What are Gamma-Rays?

Gamma-rays are caused by bursts of high-energy flashes, and though they have the smallest wavelengths, are considered the most energetic form of light. They are generally caused by the nuclear decay processes that occur in nuclear or supernova explosions, like when a massive star dies. These small bursts of light and energy are not visible to the naked eye, unless they take place under one of these extreme conditions.

What the study of gamma-rays reveals

Gamma-rays are only visible when you see shooting stars, or via satellites or high-altitude balloons set up with special instruments designed to study this phenomena. When nuclear decay takes place, creating the release of gamma-rays, a bright splash of light is seen but because of the distance to Earth, most of the light gets absorbed into the atmosphere. Only certain wavelengths of light can penetrate, therefore you see a muted version of the actual gamma-ray explosion. If you were to look at it through a special telescope, your eyes would receive the visual treat of a colorful light show; however, the fact that there is a long distance works in your favor, because gamma-rays are known to kill living cells. This fact is well known in the medical community, where scientists have harnessed bursts to help treat cancerous cells. In today's world, scientists are working hard to find other ways to harness the power of these incredible rays.

Gamma-rays, also known as gamma radiation, have fascinated the science world for some time. Without knowing it, common spectators who have witnessed a shooting star were treated to a rare glimpse at the power of these natural energy powerhouses. Despite much research, little is still known about gamma-rays and scientists studying these rays hope to uncover the mysteries of them within this lifetime.
