Scientists Uncover Universal Rule for Cosmic Ray Fading Using DAMPE Telescope
A century-old mystery about cosmic rays' origin might be solved by a newly found pattern.
Source: Science DailyScientists have discovered a hidden pattern in ultra-powerful cosmic rays, which could explain their origin. Using the DAMPE space telescope, researchers observed that cosmic ray particles, from protons to heavy iron nuclei, all show a sharp decline in intensity at the same energy level. This suggests a universal rule governs their behavior across the galaxy. This finding is significant as it provides a crucial clue to understanding the sources and acceleration mechanisms of these high-energy particles, a puzzle that has baffled scientists for over 100 years.
- Cosmic ray particles, including protons and iron nuclei, exhibit a sharp drop in intensity at a consistent energy point.
- This universal fading pattern was observed using data from the Dark Matter Particle Explorer (DAMPE) space telescope.
- The discovery could help explain the origin and acceleration mechanisms of ultra-powerful cosmic rays.
- The behavior of cosmic rays has been a scientific mystery for over a century.
- The finding suggests a common rule applies to cosmic rays across the galaxy, regardless of their particle type.
High-energy radiation, mainly originating outside the Solar System, that may produce showers of secondary particles when interacting with the Earth's atmosphere. They consist primarily of protons and atomic nuclei.
A Chinese space telescope designed to search for dark matter by observing high-energy electrons and gamma rays. It was launched in 2015 and is also known as 'Wukong' (Monkey King).
Exams often test on major scientific discoveries, space missions, and fundamental concepts in physics like cosmic rays and their properties. Focus on the instruments used and the significance of the findings.
DAMPE (Dark Matter Particle Explorer) helped 'DAMP' down the mystery of cosmic rays by finding a universal fading pattern.
