Astronomers have painstakingly built models of the asteroid population, and those models predict that there will be ~1 km sized asteroids that orbit closer to the Sun than Venus does. The problem is, nobody’s been able to find one. Until now. Astronomers working with the Zwicky Transient Facility say they’ve finally found one. But this one’s bigger,

Majestic Jupiter, our Solar System’s belligerent big brother, is putting its best side forward*. A sharp new image from the Hubble Space Telescope shows the giant planet’s wild, ever-evolving weather – revealing both short- and long-term changes. In the northern hemisphere, turbulent clouds could indicate the formation of a new swirling storm, while down south,

High above the Arctic Circle lies a group of remote Siberian islands where ivory traders and scientists brave sub-zero temperatures to search for extinct creatures preserved in the melting permafrost. Those Lyakhovsky Islands just yielded an unprecedented find: a perfectly preserved adult cave bear - with its nose, teeth, and internal organs still intact. Scientists think the

A massive chunk of ice – larger than the city of Paris – has broken off from the Arctic’s largest ice shelf because of warmer temperatures in Greenland, scientists said Monday. The 113-square-kilometre (43-square-mile) block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given the rising average temperatures.

From bird feathers to fruit skins, the natural world has two main ways of displaying colour: through pigment substances that provide selective colour absorption, or through structural colour – the use of microscopic structures to control light reflection. Now scientists have devised a computer model that explains why the brightest matte structural colours in nature

There are competing hypotheses around the decline of the Indus Valley Civilization in South Asia some 3,000 years ago, but a new mathematical proof has identified that climate change could have been responsible. Mathematical scientist Nishant Malik from the Rochester Institute of Technology crunched the numbers and found new evidence to back up the idea

Picking the kids up from school takes on a different meaning for crocodylian parents. In this photo, taken by India-based photographer Dhritiman Mukherjee, a male freshwater gharial shows us why. Bobbing in the waters of northern India’s National Chambal Sanctuary, the croc waits as more than 100 of his month-old children clamber onto his back for safe

According to ancient legend, a beautiful maiden named Ashima drowned in a river, and turned into stone. This, it has been said for centuries, is how China’s stunning Stone Forest of Shilin first took shape. According to new research, however, there’s another explanation for the phenomenon that gives stone forests their surreal and otherworldly forms,

NASA on Thursday announced it was in the market for Moon rocks, and wants to pay companies to scoop out the dirt, take a photo, and then have it ready for collection by a future mission. The contract doesn’t actually involve getting to the Moon itself – a feat only achieved by the national space

Often it’s the most minute scientific measurements that are the most important, and researchers have developed a new, super-small device that’s capable of detecting magnetic fields even when they’re extremely faint. The device, a new kind of superconducting quantum interference device (SQUID), is just 10 nanometres high, or around a thousandth of the thickness of a human
