T h e mos t famous mass ertinction (绝) was 66 milli on years ago , when it's widely believ e d tha t a meteorit e (石) kill e d off th e dinosaur s. A 110-mile-wi d e crater in Merico with th e sam e geological ag e supports this theory .Believ e it or not ,...
see that Jezero Crater is providing both really interesting igneous rocks and sedimentary rocks clearly laid down in a watery environment," says Steve Ruff, a planetary geologist and associate research professor at the School of Earth and Space Exploration at Arizona State University in Tempe, ...
Where is the largest meteor crater in the U.S.? What is Charon in outer space? What asteroid belt is between Earth and the moon? How did the Copernicus crater form? Where is the largest meteor crater in the world? What is the Wetumpka impact crater?
The intended landing spot is in the South Pole-Aitken Basin, the largest and oldest impact scar on the moon, in a crater called Von Kármán. To land on the rocky surface without guidance from Earth, Chang’e-4 will use automatic hazard avoidance to find a safe, boulder-free spot—a te...
The finding is important because scientists typically usecrater counts to date the ages of planet and moon surfaces. When comparing twosimilar regions on a moon, for example, scientists generally assume that theregion with more impact craters is older. Scientists can also use a region'scrater den...
Work in a new group. This time, change roles. SCRIPT Narrator: A giant asteroid-15 kilometers wide-is moving toward Earth very fast. Over 65 million years ago, this asteroid crashed into the Earth near Chicxulub, Mexico. It made a very large crater. The asteroid caused the extinction of...
So we can’t use size to determine if a crater is the result of a primary impact or a secondary one. And of course impactors come in different sizes… though, actually, we think there are fewer small ones than there used to be. ...
In the wake of the Alvarez duo’s stunning discovery, it initially seemed to scientists as ifa space rock impact might be a general mechanism that explained all massextinction events identified in the geological record. But the end-Cretaceous extinction is the only one reliably associated with an...
