Webb telescope reveals most detailed dark matter map ever created
Published in Nature Astronomy, the study details how Webb’s infrared instruments charted nearly 800,000 galaxies in the COSMOS field. The data reveal how dark matter – undetectable by light but dominant in mass – has shaped the universe’s structure from its earliest epochs.
Nvidia launches official GeForce Now client for Linux in beta
Nvidia announced plans to bring GeForce Now to Linux at CES 2026 a few weeks ago. The service was already available on Linux-powered handhelds like the Steam Deck, but it is now also supported on general Linux distributions for desktops and laptops.
Tesla Robotaxis are crashing more often than human drivers, data shows
Human drivers in the United States, according to NHTSA data, average a police-reported crash roughly once every 500,000 miles. Even after adjusting for underreporting to a more realistic estimate of once per 200,000 miles, people still outperform Tesla’s autonomous system by a wide margin, according to data originally surfaced by Electrek.
NASA's new Athena supercomputer delivers 20 petaflops while cutting energy consumption
Athena, NASA’s latest supercomputer, went online in January following a beta testing period. The US space agency says the new high-performance computing system can deliver more than 20 petaflops of peak performance while significantly reducing the energy required to run the extreme workloads needed to support its mission.
