Could Earth be at Greater Risk from a Deadly Asteroid Impact Than We Realize?

Detected from aerial radar surveys, the huge impact feature comprised a circular depression visible in the subglacial bedrock, around which a clearly discernible elevated rim could be seen, along with other gradually deteriorating features that had lingered since the original impact occurred. Analysis of sediment collected from the location indicated the space object that left the feature was mostly composed of iron.

In 2018, the discovery of a massive asteroid impact feature in northwest Greenland came as a surprise to many planetary scientists and others studying impact events that have occurred in Earth’s long history.

Despite being an estimated 20 miles in length, it was also clear why this particular impact feature evaded detection for so long: it was concealed beneath more than 3000 feet of ice, which had slowly accumulated since the last ice age.

If the end of mankind is going to end this century, my bet is that it will come via an asteroid collision with Earth.
