Starlink’s Wi-Fi Is Faster in the Air Than on the Ground

Starlink is nearly twice as fast as any other in-flight Wi-Fi option, according to a new report by the speed test site Ookla. (Ookla is owned by the same parent company as CNET, Ziff Davis.) Starlink’s speeds in the air are faster than some internet providers on the ground. The satellite internet company from SpaceX clocked median download speeds of 152Mbps and upload speeds of 24Mbps. Those download and upload speeds were nearly twice as fast as any other in-flight internet option, but latenc

The Films and Shows You Should Be Streaming in July 2025

A new era of streaming selections is here. For the past several years, our monthly column, the Nerd’s Watch, has been the place to find out all the best genre titles coming to the biggest streaming services. It wasn’t a complete list. We just posted the titles we think you’d care about, but it was still long, and frankly, hard to pick out the best of the best. Well, over the past few months, that changed. What follows isn’t a list of all the best stuff streaming on all the big streaming service

Pentagon may put SpaceX at the center of a sensor-to-shooter targeting network

The Trump administration plans to cancel a fleet of orbiting data relay satellites managed by the Space Development Agency and replace it with a secretive network that, so far, relies primarily on SpaceX's Starlink Internet constellation, according to budget documents. The move prompted questions from lawmakers during a Senate hearing on the Space Force's budget last week. While details of the Pentagon's plan remain secret, the White House proposal would commit $277 million in funding to kick o

OpenAI Is Shutting Down for a Week

In a bid to retain its staffers amid a Meta poaching spree, OpenAI is giving them a mandatory week-long vacation. According to insiders who spoke to Wired, a cloud of anxiety is lingering over OpenAI's C-suite as leaders scramble to keep staff happy and on their side — a tall order given that employees there often work up to 80 hours a week. Over the past week, Meta has hired at least eight OpenAI researchers to work on its new "superintelligence" team. This "recruiting coup," as the Wall Stre

Tuesday Telescope: A howling wolf in the night sky

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder. In the 1800s, astronomers were mystified by the discovery of stars that displayed highly unusual emission lines. It was only after 1868, wh

Threads gets its own DMs as app distances itself from Instagram

Instagram Threads is rolling out users’ most-requested feature to date: the ability to message people directly, without having to switch to another app, like Instagram. The company said direct messages (DMs) will begin rolling out to users globally beginning on Tuesday, alongside a new visual element called highlighter. The latter will emphasize interesting perspectives and conversations, Meta says, starting with Trending Topics. At launch, Threads DMs offer a basic set of features. They’ll su

Linux's remarkable journey from one dev's hobby to 40 million lines of code - and counting

Martin Harvey/Getty Images When Linus Torvalds posted his now-legendary 1991 announcement about a "hobby" operating system kernel, no one would have predicted that Linux would become the backbone of modern computing. In a speech at the Open-Source Summit, North America, Jonathan Corbet, executive editor of LWN and longtime kernel developer, recounted the Linux kernel's remarkable journey, highlighting its disruptive beginnings, its unique development model, and the challenges that have shaped i

Kerry Wan/ZDNET The Google Pixel 9a might be the best-value phone of 2025, especially now that it brings flagship-level AI tools, a bright 120Hz display, and a massive battery into a more affordable price tier.

To be a kid in the 1980s meant absorbing the last years of the Cold War through pop culture that played into fears about a World War III everyone assumed was coming—think WarGames, Red Dawn, and “99 Luftballoons.” Somehow that script got flipped when President Ronald Reagan announced the “Strategic Defense Initiative,” a system intended to protect the U.S. from missiles that quickly acquired its own pop culture nickname: “Star Wars.” While Reagan’s Star Wars never actually got off the ground, i

White House works to ground NASA science missions before Congress can act

In another sign that the Trump White House is aggressively moving to slash NASA’s science programs, dozens of mission leaders have been asked to prepare "closeout" plans by the end of next week. The new directive came from NASA's senior leadership on Monday, which is acting on behalf of the White House Office of Management and Budget. Copies of these memos, which appear to vary a little by department, were reviewed by Ars. The detailed closeout plans called for must be prepared by as soon as Ju
