Of all the craters on Pluto’s moon Charon, this one is unlike the others. The bright green marks a unique splash of frozen ammonia at a concentration higher than any other crater examined in detail on the massive moon. But does that mean it’s the youngest?
Pluto has been puzzling us with its weirdly smooth surface, but if it’s the first Kuiper Belt Object we’ve visited, how did we know how many craters to expect in the first place? Here’s everything we’ve figured out about collisions in this chaotic area of our Solar System.
When we think of craters, asteroid collisions are often what come to mind. But now, thanks to scientists who exploded balloons in a sand box, we have a better idea of other ways craters can be formed, like underground methane explosions, for instance.
Science is meant to be an unceasing, always-sceptical search for knowledge, so it’s not often that scientists can call it a day, declare a problem all scienced out, and move on. But that’s exactly what the team counting asteroid craters on Earth are doing.
Sixty-five million years ago, a meteorite careened into Earth, leaving a huge crater on the coast of the Yucatan Peninsula. The impact is likely responsible for killing off the most of the dinosaurs—along with 75 percent of all species on Earth. Scientists are now planning an expedition to drill into the…
The Messenger spacecraft has photographed some neat craters on Mercury's surface and NASA thinks they look like the cookie monster. What kind of magic cookies are you eating, NASA? Hmmm, wait. I think they are right.
Some scientists are starting to believe that our moon is actually the result of a mid-air space collision of two moons. They say that the two-moon theory could explain why each side of the moon is so different from the other.
