What exciting events will we see in the southern sky in 2024? Meteor showers, Saturn covered by the Moon, close approaches of bright planets to each other, supermoons — and, if we’re lucky, a comet visible to the naked eye. Even if you live in a city surrounded by light pollution, these are all worth ...
As an astronomer and meteor enthusiast, the Geminids make this the most wonderful time of the year. Each December sees the return of the Geminid meteor shower — the best natural fireworks display of the year — and people the world over head out to enjoy the show.

The idea that dinosaurs are still alive has captured the imagination of many around the world. It is said that one day 66 million years ago, something catastrophic happened that led to the extinction of all non-avian dinosaurs from the surface of the Earth. However, evidence suggests dinosaurs may have been on the path to ...
Organic molecules found in a Martian meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to a new analysis led by Carnegie’s Andrew Steele and published by Science. The meteorite, called Allan Hills (ALH) 84001, was discovered ...
The beginning of the end caused by a meteor strike started with violent shaking that raised giant waves in the waters of an inland sea in what is now North Dakota. Then, tiny glass beads began to fall like birdshot from the heavens. The rain of glass was so heavy it may have set fire ...
Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, potentially threatening a collision. NEOs are tracers of the composition, dynamics, and environmental conditions throughout the solar system, and of the history of our planetary system. Most meteorites come from Near Earth Objects, which are thus one ...
While exploring volcanic rocks on Scotland’s Isle of Skye, geologists made a discovery literally out of this world — mineral forms that have only ever been found in space. The minerals were thrown out from a 60 million-year-old meteorite impact, previously unknown to scientists. This makes it the first known meteorite impact designated within the British Paleogene ...
It has never really been understood how our atmosphere protects us against meteoroid impacts. It’s well recognized that meteoroids often explode before they reach Earth’s surface; however, researchers were uncertain as to why this happened until now. Researchers from Purdue University have discovered our atmosphere is a better shield from meteoroids than previously thought. They ...
