Locating meteorites on Earth’s surface is like looking for a needle in a haystack, but using AI to analyse images captured by drones pinpointed a tiny space rock in just four days Technology 11 March 2022 By Chen Ly The meteorite as seen by the drone and algorithm: the yellow box is 100 square centimetres … Read more
An enormous impact crater, hiding deep beneath Greenland’s Hiawatha glacier, is probably the result of a kilometer-wide asteroid that crashed into Earth 58 million years ago. That’s much older than scientists presumed – roughly eight million years after the infamous impact that killed off most dinosaurs. When the Hiawatha crater was first discovered in … Read more
A meteor that exploded in the sky over Chelyabinsk, Russia in 2013 could have also been somehow involved in the giant impact that formed the Moon. This tantalizing finding comes thanks to a new way of dating collisions between rocks in space, based on microscopic analysis of minerals within meteorites. Although further investigation is warranted, … Read more
You may already know the legend of King Tutankhamen’s space dagger – an iron weapon forged from the rock of meteorites, and entombed with the ancient Egyptian pharaoh. Now a new study has revealed more details about this most fascinating and mysterious of artifacts. A thorough chemical analysis involving high-resolution photography and X-rays has … Read more
Early chances for life on Mars might have been diminished by meteorites. A new study suggests that a period of heavy cratering on the Red Planet (and elsewhere in the solar system) persisted 30 million years longer than thought. Studies of the Late Heavy Bombardment, as this period is called, also has implications for the … Read more
We don’t know how life emerged on Earth, but one thing is certain: life as we know it on our planet wouldn’t exist without the water that wraps around the surface, runs in rivulets, and falls from the sky. Our planet is the only one known to have life, and the only one on … Read more
More than 1500 years ago, a vast culture known as the Hopewell tradition (or Hopewell culture) stretched across what is today the eastern United States. The cause of the culture’s decline has long been debated, with war and climate change two of the possibilities, but now a new avenue of inquiry has opened up: debris from a … Read more
Evidence for an intense asteroid impact on Mars has been found in a Martian meteorite, which could alter the timeline for when the red planet might have been habitable. In a famous meteorite named NWA 7034, or ‘Black Beauty’, scientists discovered a shocked crystal of the mineral zircon, showing a feature only seen on Earth … Read more
An artificial intelligence program suggests there may be hundreds of thousands of meteorites left for scientists to discover on the icy fields of Antarctica and reveals what may be the most likely places to unearth them, a new study finds. Nearly two-thirds of all meteorites recovered on Earth originate in Antarctica. The cold, dry nature … Read more
To date, we’ve found over a hundred precious Mars rocks that have travelled from the red planet and landed on Earth at some point. Among those, specimen ALH84001 might well be one of the most enigmatic. This meteorite fragment was picked up during a snowmobile ride in the ice field of Alan Hills in Antarctica … Read more
