How can you tell if a crater is recent? The rim is sharp and the material ejected from its formation is well-preserved. Since it’s relatively recent — in geological time — this crater could have a “steep, active slope,” so NASA will monitor it for changes.
This crater on Mars is so fresh, it still has sharp, clean edges unsoftened by countless landslides.
A crater on Mercury bares the name of Liang Kai, a human painter from China's Southern Song Dynasty. While Kai is from hundreds of years ago, living 1140 to 1210 CE, substantial erosion and infilling indicates his crater is much older.
With a gentle rainbow of topographical changes, and the scalloped detail of active dunes, this digital terrain model is pure indulgence for the eyes. It's also part of an ongoing study on using aeolian processes to investigate sedimentation and atmospheric science on Mars.
The walls on the sides of Zumba Crater on Mars are so steep, it looks like an eyeball staring back at you from the digital terrain model. The ejecta forms a hill of red and brown around the perfectly circular blue crater floor.
This impact crater on Mars is decked out in rainbow colours reflecting the topography of the area. The dark blues and purple of the crater floor rapidly digs through the high-elevation red, yellow, and green of the surrounding plains.
Selenography, the study of surface and physical features of the Moon, is a field where science meets art. From careful engravings and sketches of early observations to lunar photography, it is all gorgeous. So settle in, and enjoy some lunar eye-candy.
Where on Earth is this freaky lava pool? Why do people hate love locks? Is it true that fire ants love the suburbs? And what do the soon-to-be-lost sounds of the industrial age sound like? All your answers are here, in this week's landscape reads!
This well-preserved crater on Mars features evidence of mass wasting — reoccurring slope linea formation. Material is being eroded from the high-elevation crater lip, forming shifting gullies into the basin below.
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?
This photo from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows a fresh crater about 100 feet (30 meters) in diameter at the center. The impact happened somewhen between July 2010 and May 2012. View the map-projected version of the image here:
From destruction comes rebirth. Chinese architects Xiaomia Xiao, Lixiang Miao, Xinmin Li, and Minzhao Guo dream up a world in which a devastating asteroid has hit, and we use the crater as the site of a thriving city.
The asteroid that hit Earth 65 million years ago and wiped out the dinosaur was at least six miles across and left behind a crater over 110 miles across. But that's nothing compared to a possibly newly discovered impact site.
It looks like something between the Nickelodeon Astro Crag and a piece of swiss cheese, but Timbuk2's latest sleeve has a lot of thought behind it. The casing is meant to ventilate your laptop—just watch for rain.
Things can be pretty slow-going on the red planet for NASA's Mars rover Opportunity. Since January of 2004, the solar-powered Opportunity has been chugging along the planet's surface at a leisurely pace of 60 centimeters an hour, but there's exciting news on the horizon. Or rather, its horizon.
NASA's Messenger probe has already taken thousands of photos of Mercury's surface after coming into orbit around the planet earlier this week. And it's got plenty still to do, including searching for hidden pockets of ice on Mercury's boiling surface.
Most of the craters created by meteorite and asteroid impacts are round, nothing like this strangely elongated, oval-shaped crater recently discovered on Mars. This crater just might be the trendiest meteorite landing spot on all of Mars.
Scientists are suggesting that two different meteors, not a single strike, may have wiped out dinosaurs some 65 million years ago. Interestingly, they struck Earth thousands of years apart.
