Gamma-ray bursts (GRBs) are the largest known generators of gamma rays. These are extremely energetic explosions that occur in distant galaxies, emitting more energy in a few seconds than our Sun will over its entire lifespan. Scientists believe they result from the collapse of massive stars or the merger of neutron stars.
FAQs & Answers
- What causes gamma-ray bursts? Gamma-ray bursts are believed to occur due to the collapse of massive stars or merging neutron stars, releasing enormous amounts of energy.
- How often do gamma-ray bursts occur? Gamma-ray bursts are relatively rare, occurring roughly once every few seconds somewhere in the universe, but they can be detected from billions of light-years away.
- What is the significance of gamma-ray bursts in astrophysics? Gamma-ray bursts provide insights into the early universe, star formation, and the fundamental forces of nature, making them essential for astrophysical research.
