Astronomers Detect Entirely New Type of Plasma Wave Above Jupiter’s North Pole

gizmodo.com Gayoung Lee 2025-07-20 10:00:55

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 of plasma waves in Jupiter’s magnetosphere—a magnetic “bubble” shielding the planet from external radiation.

Origami Space Planes Could Solve a Major Problem in Orbit

gizmodo.com Passant Rabie 2025-07-20 05:10:56

Building a spacecraft could one day be as simple as folding a piece of paper into a plane and letting aerodynamics do the rest. A team of researchers from the University of Tokyo simulated the release of a paper airplane from the International Space Station (ISS) to see if would survive atmospheric reentry. In a paper published in Acta Astronautica, the researchers demonstrated how origami may be the solution to low Earth orbit’s growing trash problem. Rather than relying solely on metals to co

Debcraft – Easiest way to modify and build Debian packages

news.ycombinator.com Unknown 2025-07-20 06:04:31

Debian packaging is notoriously hard. Far too many new contributors give up while trying, and many long-time contributors leave due to burnout from having to do too many thankless maintenance tasks. Some just skip testing their changes properly because it feels like too much toil. Debcraft is my attempt to solve this by automating all the boring stuff, and making it easier to learn the correct practices and helping new and old packagers better track changes in both source code and build artifac

A New Geometry for Einstein's Theory of Relativity

news.ycombinator.com Steve Nadis 2025-07-21 03:19:17

Kunzinger and Sämann wanted to use their new way of estimating curvature to determine whether these singularity theorems would still be valid if they no longer assumed space-time is smooth. Would singularities persist even in rougher, more realistic-looking spaces? It’s important to find out if the smoothness condition can be waived, Sämann said, because doing so would bring the theorems closer to physical reality. After all, he added, “we believe non-smoothness is an inescapable part of the nat

The success was that after Huby founded The Exploration Company in Europe, she managed to move nimbly with the "Mission Possible" spacecraft such that it cost less than $25 million to build and reached space in less than three years.

TCP-in-UDP Solution (eBPF)

news.ycombinator.com Matthieu Baerts 2025-07-19 17:59:08

The MPTCP protocol is complex, mainly to be able to survive on the Internet where middleboxes such as NATs, firewalls, IDS or proxies can modify parts of the TCP packets. Worst case scenario, an MPTCP connection should fallback to “plain” TCP. Today, such fallbacks are rarer than before – probably because MPTCP has been used since 2013 on millions of Apple smartphones worldwide – but they can still exist, e.g. on some mobile networks using Performance Enhancing Proxies (PEPs) where MPTCP connect

A gritty Pac-Man reboot makes for surprisingly solid Metroid-style action

Shadow Labyrinth didn’t make the best first impression, though I’m not talking about the game itself. The concept of a gritty reboot of Pac-Man first reared its strange head in Secret Level, an anthology that turned notable video games into animated shorts that mostly felt like extended commercials. And that’s exactly what the episode “Circle,” which reimagined Pac-Man as a blood-soaked survival story, turned out to be.

A Meteor Impact May Have Caused a Giant Landslide in the Grand Canyon

How could the material possibly have reached that height?
