Researchers working in the Barents Sea have discovered hundreds of craters on the Arctic Sea floor, some measuring over a kilometer in width. These craters, which date back to the end of the last Ice Age, were formed when large reserves of methane exploded in the wake of retreating ice sheets. Because methane is a…
We have a good idea of what those bright spots on Ceres are, but the question of how they got there remains mysterious. Now, an incredibly low-altitude image of the dwarf planet reveals details about their origins.
Here is how subsidence craters are formed: an underground nuclear explosion gets set off and creates a hole underneath the ground. The ground collapses because nothing is supporting it anymore and then boom, giant crater. It is so gnarly to see because the ground looks like its melting into the core of the Earth.
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 middle of the…
Remember that dramatic 260-foot crater that was discovered in Siberia this past summer? In an effort to learn more about this mysterious hole, a team of Russian geologists has successfully climbed down to the bottom where they managed to perform tests and take some stunning photos.
Russian geologists are on their way to a remote region of Siberia's Yamal Peninsula to investigate the mysterious appearance of what looks like a gigantic Sarlac Pit. Opinions are divided as to what caused the apparent crater.
Newest research sez, volunteer citizen-scientists with the Moonmappers project do just as well as trained experts at mapping craters on the moon. This research is vital for understanding relative ages, odds of impact events, and how our solar system has evolved over time.
The moon is full of craters both large and small, but typically they come in only one shape: round. So why are scientists spotting square craters on the moon?
NASA's Mars Orbiter has discovered a brand new impact crater on the Martian surface — and it's a beauty.
Back in March, the Moon was struck by a meteoroid travelling 56,000 mph. The resulting explosion released the equivalent of five tons of TNT — a flash that could be seen from Earth with the naked eye. NASA has now released an image of the moon's latest feature.
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.
Mars isn't the only planet with awe-inspiring craters. Here on Earth, we've been pummeled by space rocks in the not-so-distant past, and our planet has the scars to prove it. A new photo essay in National Geographic by Stephen Alvarez tells the story of planetary impacts like this one (above) in Arizona, U.S., called…
