Summary:
- This article discusses a new study that has found evidence of a massive impact crater under the Greenland ice sheet. The crater is estimated to be at least 19 miles (31 kilometers) wide, making it one of the 25 largest impact craters on Earth.
- The crater was likely formed by a meteorite impact that occurred less than 3 million years ago, which is considered recent in geological timescales. This impact event may have had significant effects on the local environment and climate at the time.
- Further research is needed to determine the exact age and impact of this crater, but it represents an important discovery that can provide insights into the geological history and evolution of the Greenland ice sheet and the surrounding region.
