The closest Gamma-Ray Burst (GRB) to Earth was GRB 980425, which occurred roughly 140 million light-years away in the galaxy ESO 184-G82. While this distance is monumental compared to everyday scales, it is relatively close in astronomical terms. GRBs are incredibly powerful and rare events that occur when massive stars collapse or merge. Though fascinating, such events pose no immediate threat to our planet.
FAQs & Answers
- What is a Gamma-Ray Burst? A Gamma-Ray Burst (GRB) is an extremely energetic explosion that occurs in distant galaxies, often resulting from massive star collapse or the merger of neutron stars.
- How often do Gamma-Ray Bursts occur? GRBs are rare events, occurring at a rate of approximately one per day in the observable universe, but they can be detected across vast distances.
- Can Gamma-Ray Bursts harm Earth? While GRBs are incredibly powerful, the closest known burst, GRB 980425, poses no immediate threat to Earth due to its significant distance.
