Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.
The crater left by the asteroid that wiped out the dinosaurs is located in the Yucatán Peninsula. It is called Chicxulub after a nearby town. Part of the crater is offshore and part of it is on land. The crater is buried beneath many layers of rock and sediment. A 2016 mission led by the International Ocean Discovery Program extracted rock cores from the offshore portion of the crater.

Study Describes Key Stage in the Beginning of Great Glaciations
Written by AZoCleantechFeb 22 2021
A key stage at the start of the great glaciations has been described for the first time by a new study in which the Andalusian Earth Sciences Institute (IACT) (CSIC-UGR) was involved. The study suggests that it can occur again to Earth in the future.

The results of the study, which were published recently in the scientific journal
Nature, claim to have identified a new link that could offer insights into the start of the ice ages on Earth.
