In volcanic eruptions, collisions between ash particles can sometimes build up enough electric charge for lightning to arc through the plume. Scientists have long debated how this happens–it’s not obvious that insulating materials like oxides would build up electric charges through contact, especially when dealing with substances of the same material.

If you fill a test tube with water and drop it, the impact causes a pressure wave that travels up from the bottom and creates a focused jet (left). (Image credit: H. Watanabe et al.)

Uranus is one of our solar system’s oddest inhabitants, stuck spinning on its side with a tilted and offset magnetosphere. To better understand it, a team observed the planet for 17 hours with JWST.

If you’ve ever seen crashing waves glowing blue, you’ve been treated to bioluminescence. Although many creatures can bioluminesce, tiny dinoflagellates–a type of marine phytoplankton–are one of the easiest to spot.  (Image credit: T. McKinnon; research credit: P. Kumar and J. Picardo)

In 1604, astronomers first caught sight of Kepler’s Supernova Remnant, a massive explosion some 17,000 light-years away. Twenty-five years of observations from the Chandra X-ray Observatory went into making this timelapse, which shows the supernova remnant’s material pushing into the surrounding gas and dust.

Venus is a world of extremes. A full rotation of the world takes 243 Earth days, but winds race around the planet at a speed that makes a Category 5 hurricane look sedate. Just what drives these winds has been an ongoing question for planetary scientists. A recent study suggests that tides are a major contributor to this superrotation.

Inside a fusion reactor, magnetically-contained plasma gets heated to more than one hundred million degrees. That heat, researchers observed, spreads much faster than originally predicted. Now a team from Japan has measurements showing how turbulence manages this feat. (Image credit: National Institute for Fusion Science; research credit: N.

The Osage Nation in Oklahoma, with help from allies at the Nature Conservancy and the Bronx Zoo, are reviving their cultural and spiritual connection to buffalo by rebuilding a herd that once shared their land. By reigniting traditional land management practices like prescribed fire, the Osage support the herd as it continues to grow, which in turn, restores natural balance that helps the entire prairie ecosystem thrive.

Did you know that the headquarters of Ferrari, Lamborghini, and Maserati are located within ~25 km of each other?
