Scientists guide lightning bolts with laser beams for first time

Lightning rods have been used to guide lightning strikes for centuries, but now scientists have demonstrated something a bit more advanced than a humble metal stick. Beaming a high-powered laser into the sky was shown to deflect lightning bolts, which … Continue reading Scientists guide lightning bolts with laser beams for first time

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?

Hubble’s “magnum opus”: most precise measurement of universe’s expansion

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.Continue Readi… Continue reading Hubble’s “magnum opus”: most precise measurement of universe’s expansion
