Iron Nitrides: Powerful Magnets Without the Rare Earth Elements

Since their relatively recent appearance on the commercial scene, rare-earth magnets have made quite a splash in the public imagination. The amount of magnetic energy packed into these tiny, shiny …read more Continue reading Iron Nitrides: Powerful Magnets Without the Rare Earth Elements

“Gigantic jet” lightning blasts record-breaking bolt upwards into space

While a thunderstorm can put on quite a show for spectators on the ground, the best bits often happen above the clouds. Scientists have now described in detail the most powerful “gigantic jet” of lightning ever observed, which blasted energy equivalent… Continue reading “Gigantic jet” lightning blasts record-breaking bolt upwards into space

What is gravitational lensing and how can the James Webb Telescope use it?

If you’ve seen the first images from the James Webb Space Telescope (JWST) this week (and let’s face it, how could you not?), you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help … Continue reading What is gravitational lensing and how can the James Webb Telescope use it?

World’s most powerful X-ray laser now fires a million bursts per second

The world’s most powerful X-ray laser is ready for operation after a massive overhaul. A powerful upgrade to Stanford’s Linac Coherent Light Source (LCLS), LCLS-II uses temperatures colder than deep space to accelerate electrons to near light-speed and… Continue reading World’s most powerful X-ray laser now fires a million bursts per second
