The extinction of the dinosaurs was a mystery for a long time, with the predominant theory by later in the 20th century being that massive systems of volcanoes (e.g. the Deccan Traps) cooled the climate over millions of years with continuous emissions of volcanic gases into the stratosphere....
which marks the impact that may have ultimately killed the dinosaurs 65 million years ago. The Chicxulub space rock is thought to have been 6 miles wide, while the Wilkes Land meteor could have been up to 30 miles wide, the researchers said. ...

air that globally blocked out views of the Sun for years or decades. After the initial blast, the reduced sunlight caused Earth’s surface temperature to plummet by as much as 50 degrees Fahrenheit (28 degrees Celsius), aiding in a mass extinction that killed 75 percent of life on ...
Discovery of a large impact crater beneath the North Atlantic Ocean reveals that more than one asteroid could have spelled doom for the dinosaurs. A newly discovered impact crater below the seafloor suggests that more than one asteroid may have hit Earth during the time when dinosaurs...
The meteor that sealed the fate of the dinosaurs landed at this site, one of the largest impact craters in the world.
A three-mile-wide object-still much smaller than the one that most likely killed the dinosaurs-delivers more energy at the moment of impact than all our planet's earthquakes, volcanoes, and tsunamis typically release over hundreds of years. Short of the sun going nova, an asteroid impact is...
Scientists discover there wasn’t just one asteroid which killed dinosaurs –after 66 million years 科学家们发现,6600万年前,恐龙灭绝不仅仅是因为一颗小行星的碰撞 A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth...
Sixty-six million years ago, an asteroid the size of a small city smashed into the earth. This impact, the one that would lead to the end of the dinosaurs, left a scar several miles underground and more than 115 miles wide. Chicxulub, which lies underneath the Yucatán Peninsula of Mexic...
