A new study suggests that the ancient Earth could have been donut-shaped for at least a century.
The DAWN spacecraft discovered that the dwarf planet Ceres is missing massive craters that are supposed to be there.
Tech giants are known for their contributions to society in terms of information, communications and technology. In light of issues hounding the environment, here are five companies and their impact on our planet.
Glass deposits discovered in impact craters on the surface of Mars may hold signs of ancient life, adding to the growing evidence that the Red Planet was once habitable.
Scientists have long wondered how our Blue Planet came to be covered by 70 percent water. Now a new study offers fresh evidence for how water reached Earth, finding that asteroids and comets are likely rich in water.
On March 18, 2011, NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft finally inserted itself into orbit around Mercury after six and a half years of traveling across our solar system. Now the 11-year-old spacecraft is finally retiring, with plans to end its career by leaving its mark on the planet it observed for so long.
About 65 million years ago, an asteroid crash supposedly wiped out all the dinosaurs on Earth. Now, scientists may soon finally solve the mystery behind this dino-killing crash.
The Moon: it's a heavenly body of changing faces and meaning. It's commonly associated with horror, romance, and above all, mystery. And even answers concerning how it came to be have remained unknown... until now.
Two years ago, an object the size of a small boulder slammed into the surface of Earth's Moon with immense force, creating a flash of light nearly 10 times brighter than anything lunar impact ever recorded. Like many impacts before it, the collision changed the face of our moon forever, adding several new craters and altering old ones. Now NASA experts are working to distinguish the new from the old - identifying the Moon's freshest craters to help them better understand these kinds of impacts.
During the violent beginnings of early Earth some 4.6 billion years ago, it seems that weathermen could have forecast iron rain - storms that supposedly led to the formation of the Earth's core and even the Moon, according to a new study.
Imagine this: Our solar system is busy minding its own business, whittling its days away in its predictable orbits and rotations, when suddenly a rogue star comes crashing by, knocking comets and asteroids into erratic paths straight for Earth. A new study says that such a scenario is entirely possible, but it's nothing to fret over.
It is thought that about 66 million years ago, a massive impact led to the full extinction of the dinosaurs (potentially with the help of volcanoes and disease), and a significant portion of prehistoric sea life. Now researchers have found evidence that even the great majority of mammals at this time did not escape destruction.
Researchers have recently released oil in part of the North Sea as a part of a contained experiment to better understand exactly what happens within the first few days of a spill. This, they claim, will provide them valuable insight in how to better mitigate an oil spill's adverse effects.
