NASA Mission to Map Sun’s Protective Bubble Could Help Better Predict Dangerous Space Weather

gizmodo.com Passant Rabie 2025-09-19 01:38:43

The Sun is an energetic star, constantly radiating energy and pumping streams of charged particles out into space. And while this solar wind can be dangerous in itself, without it, Earth and all the other members of our planetary system would be at constant risk of threats from outer space. Our host star creates a protective bubble called the heliosphere that extends far beyond the orbit of Neptune, shielding the planets from the interstellar medium. Yet though we may owe our existence to this b

Adjacency Matrix and std:mdspan, C++23

news.ycombinator.com Unknown 2025-09-26 10:14:20

In graph theory, an adjacency matrix is a square matrix used to represent a finite (and usually dense) graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not, and in weighted graphs, they store the edge weights. In many beginner-level tutorials, adjacency matrices are implemented using vector of vectors (nested dynamic arrays), but this approach has inefficiencies due to multiple memory allocations. C++23 introduces std::mdspan , which provides a more efficient

Altered states of consciousness induced by breathwork accompanied by music

The popularity of breathwork as a therapeutic tool for psychological distress is rapidly expanding.

A Physicist Wants to Turn Jupiter’s Largest Moon Into a Gigantic Dark Matter Detector

When searching for the unknown, classic physics wisdom holds that a bigger detector boosts the chances of discovery. A physicist is taking that advice to heart, advancing a bold plan to use none other than Ganymede—Jupiter’s largest moon—as a dark matter detector on an astronomical scale. Dark matter refers to the “invisible” mass that supposedly constitutes 85% of the universe. There’s considerable evidence that dark matter exists, but it’s “dark,” meaning it doesn’t respond to light and very
