Astronomers using JWST have captured the clearest view yet of a doomed red supergiant star just before it exploded, solving a decades-old mystery about why such stars rarely appear to go supernova.
Duplicating expensive resources is expensive and wasteful, and most people would agree it's unnecessary. However, the planned increase in major satellite constellations is currently causing a massive duplication of resources as individual companies and even countries try to set up their own infrastructure in space. What’s more, there is a relatively limited amount of space in Low Earth Orbit (LEO), where many of these satellites are supposed to go - any more than that and a single collision could cause Kessler Syndrome, where many of the ones already in orbit would be destroyed and we wouldn’t be able to launch any more for a long time. A new paper from researchers at the National University of Defense Technology in China suggests an alternative to these multiple megaconstellations - a single, modular system similar to how cloud computing works on the current internet.
