Since entering Jupiter’s orbit in 2016, NASA’s Juno spacecraft has been hard at work unveiling the many mysteries of our solar system’s largest planet. And its latest discovery may be one of the most intriguing yet: an entirely new type of plasma wave near Jupiter’s poles.  In a paper published Wednesday in Physical Review Letters, astronomers describe an unusual pattern …

Human sperm have long been a subject of fascination—not just for their role in fertilization, but for their remarkable ability to navigate through some of the most viscous environments in the body. But a recent study published in PRX Life has raised a surprising question: do sperm really follow the laws of physics? The answer, it turns out, is more …

These mysterious “fireworks” aren’t lighting up the night sky — they’re computer simulations from a recent paper on mixing fluids that don’t want to mix. Researchers mapped out how two immiscible fluids (two fluids that do not mix, like oil and water) with different viscosities can create “fingers” when they interact. They created different patterns by alternately injecting the fluids …

The Day Mars Died – 60th Anniversary of Mariner 4 – YouTube Watch On On Episode 169 of This Week In Space, Rod Pyle and Tariq Malik are joined by Rob Manning, JPL’s Chief Engineer Emeritus, to look back at the Mariner 4 Mars mission 60 years later. Six decades ago this week, the Mariner 4 probe sped past Mars, …

In a recent study, divers near Kumejima Island in Japan discovered an unusual sea creature with a distinctive panda-like appearance. These creatures, part of the Clavelina genus, were first thought to be part of an aquarium display, only to surprise researchers by being a completely new species. The discovery has drawn attention from marine biologists and citizen scientists alike, as …

Astronomers have spotted the earliest known signs of rocky planet formation around a young, sun-like star for the first time. The discovery offers an unprecedented glimpse into what may have happened at the dawn of our own solar system. What did the researchers see? Using NASA’s James Webb Space Telescope and the European Southern Observatory’s ALMA array in Chile, researchers …

The world of Bousso’s new theorem still departs from our universe in notable ways. For mathematical convenience, he assumed that there’s an unlimited variety of particles—an unrealistic assumption that makes some physicists wonder whether this third layer matches reality (with its 17 or so known particles) any better than the second layer does. “We don’t have an infinite number of …

IN A NUTSHELL 🌞 Solar storms are causing SpaceX’s Starlink satellites to reenter Earth’s atmosphere sooner than planned. 🚀 The increased atmospheric drag from geomagnetic storms shortens the satellites’ lifespan by 10 to 12 days. ⚠️ A higher risk of satellite collisions emerges due to unpredictable drifts caused by solar activity. 🛰️ Managing a crowded orbit is crucial as more …
