How to Weigh a Killer Asteroid at 22 Kilometers per Second March 2, 2026
Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about it, after its trajectory. Actually doing so isn’t easy though, as the mass for objects in the tens to hundreds of kilometers in size are too small to have their mass calculated by traditional radio-frequency tracking […]
Predicting the Sun's Most Violent Outbursts March 2, 2026
In the first four days of February this year the Sun unleashed six powerful X-class flares in rapid succession including an X8.1 that was the strongest in several years. And now, scientists have announced a new forecasting system that could give us up to a year's warning before the most dangerous solar storms arrive. The […]
How Long Do Civilisations Last? March 2, 2026
In 1950, the physicist Enrico Fermi sat down to lunch with colleagues and asked a question that has haunted astronomers ever since. If the universe is so vast, so old, and so full of stars, where is everybody? A new study has turned that question around and come up with an answer that is quietly […]
What the Moon Rocks Were Hiding March 2, 2026
The rocks that twelve astronauts carried home from the Moon fifty years ago have just rewritten our understanding of lunar history. A new analysis of Apollo samples has finally resolved one of the most stubborn debates in planetary science and the answer turns out to be one that neither side of the argument was entirely […]
Laser-Based 3D Printing Could Build Future Bases on the Moon March 2, 2026
Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it […]
