Earth has not been directly hit by a gamma-ray burst (GRB). Such an event could cause significant damage to our atmosphere and potentially lead to mass extinctions. However, scientists study GRBs from distant galaxies through telescopes, and there is no evidence suggesting that a direct hit by a GRB has occurred in Earth's history.

FAQs & Answers

  1. What is a gamma-ray burst? A gamma-ray burst (GRB) is a highly energetic explosion observed in distant galaxies, emitting intense gamma radiation for brief periods.
  2. Could a gamma-ray burst cause mass extinction on Earth? Yes, a direct hit from a gamma-ray burst could damage Earth's atmosphere significantly, potentially leading to mass extinction events.
  3. Have we ever detected gamma-ray bursts near Earth? Scientists have observed gamma-ray bursts from distant galaxies, but there is no evidence that Earth has ever been directly hit by one.
