The researchers looked at large impact craters that occurred within the last million years on Earth.
Dinosaurs witnessed the wrath of a massive space rock striking the planet with incredible force. The catastrophic event was so powerful that it completely wiped out these
from the planet. And so, whenever there's a report of an asteroid passing through Earth, it does send shivers down one's spine.by our planet from afar. However, we don't know how large and energetic this impact could be in the worst-case scenario. Goddard Space Flight Center's chief scientist, James Garvin, and his team went on to find the answer to this troubling question.The actual size of impact craters is bigger than estimated
The team precisely measured the size of the recent impact craters. Worryingly, their analysis revealed that the crater sizes were larger than previously calculated. Simply put, the Earth and its environment would take a direct hit after being smashed by an asteroid.
Scientists had previously overlooked the true size due to Earth's dynamism, such as water, wind, and tectonics, which erase the rims around the craters. As a result, the faint outer rims were obscured.
