Over 90 percent of mammals were wiped out by dino-killing asteroid

By now, most people are familiar with the theory that an asteroid that smacked into our planet 66 million years ago caused the extinction of the dinosaurs. But it turns out that dinosaurs might not have been the only casualty of that cataclysmic event. New analysis of the fossil record indicates that a full 93 percent of mammals living at the time also went extinct, a number significantly higher than previously thought.Read More

Earth picks up asteroid traveling companion

An asteroid dubbed 2016 HO3 has recently been discovered that, whilst technically in orbit around the sun, is also spinning in its own merry dance around the Earth. Somewhere between 120 ft (40 m) and 300 ft (100 m) in size, our little travelling partner is estimated to have been in step with our orbit for about a hundred years now, and will continue to do so for at least many hundreds more. Too far away to be identified as a satellite to our planet, it is stable enough at the moment to be seen as a near-Earth companion body. Read More

Meteorite discovery: "No one has seen anything like this one before"

About 470 million years ago, two asteroids smashed into each other in outer space and shattered into multitudinous pieces. Many of those pieces rained down on Earth over the course of a million years as meteorites, and have become well-known by scientists. But the other space rock involved in the cosmic head-on collision has never been known – until now, thanks to the discovery of a meteorite that's never been seen before on our planet.Read More

Evidence of gargantuan asteroid strike unearthed in Australia

All it takes is a quick look up at the moon to understand what a violent place the early solar system was. All those craters are the results of asteroids smashing into the lunar surface. The Earth was likewise battered all those billions of years ago, but the evidence of many asteroid strikes has long been erased through topography changes. Researchers at Australian National University (ANU) though, have found clues to a massive asteroid that impacted our planet about 3.5 billion years ago, when the Earth was less than a quarter as old as it is now.Read More

The cosmos created from cinnamon, spice and ... cat hair?

For most of us, spilling some sugar or cinnamon on the glass of our scanner would be an accident. For photographer Navid Barraty, it's art. Barraty uses ordinary food, kitchen staples and other odd bits and pieces along with his Epson scanner to create enchanting cosmic worlds. Pancakes become planets, potatoes become asteroids and cat fur – yes cat fur – helps create a striking nebula. Have a look at this new series and see if you can guess what the images are comprised of – before you read the captions. Read More

See NASA's most detailed flyover video of Ceres

Since December, NASA's Dawn spacecraft has been as close as it will get to the surface of Ceres, the largest object in the asteroid belt. The space agency and its Jet Propulsion Laboratory have put together the most comprehensive video tour yet from the spacecraft's lowest mapping orbit.Read More

Hyabusa2 slingshots to asteroid encounter

The Japan Aerospace Exploration Agency confirmed today that its Hayabusa2 probe has successfully used the Earth's gravity to slingshot itself towards a rendezvous with an asteroid. The flyby maneuver saw the unmanned spacecraft swing by the Earth on December 3, with the closest approach of 3,090 km at 7:08 pm JST as it passed over the Pacific Ocean near the Hawaiian Islands.Read More
