Scientists drill into crater off Mexico's east coast extracting the remains of the asteroid widely blamed for the demise of the dinosaurs.

For now, they know that the asteroid's impact was so powerful caused material to fly into orbit and fall back into Earth like fireballs. Later, ash covered the skies, turning the planet into a dark and cold place.

"This created a chain of extinction. Months later, the dust fell on the continents and oceans, changing the chemistry of the oceans," said expedition chief Jaime Urrutia, president of the Mexican Science Academy.

While there are still debates about whether the asteroid is solely to blame for the disappearance of dinosaurs, scientists agree that it caused great destruction and had a role in how life evolved after its crash.http://phys.org/news/2016-05-sea-scientists-drill-crater-dino.html?utm_source=nwletter&utm_medium=email&utm_campaign=daily-nwletter

In mid-March, drilling by paleoclimatologists to retrieve sediment and meteorite-impact rocks from remotest Siberia reached about 213 feet (65 m), about 1 million years into the past. They hope to retrieve the longest continuous climate data ever collected for the Arctic, over 3.6 million years.
