Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth's atmosphere. Different wavelengths of light penetrate the Earth's atmosphere to different depths.

I learned that this bursts provide us with an exciting opportunity to learn new concepts of physics and to educate myself on how was the universe in the era of star formation. Space and earth exploration in the next years will be very exciting. Every day the human race uncovers what was one a puzzling mystery.
