A planetary defense system would blunt solar storms with hundreds of tons of gas. Emerging heavy-lift rockets could deploy it in under two months.

Extreme space weather could wreak havoc on the satellites, communications networks, and electrical grids that modern society depends on. Researchers have now proposed an ambitious space-based planetary defense system that would weaken solar storms before they hit Earth.

The sun regularly emits massive pulses of radiation, energetic particles, and magnetic fields that interact with the Earth’s own magnetic field. This activity is the source of auroras like the northern lights, but the most violent eruptions can cause geomagnetic storms with the power to disrupt GPS and radio communications and fry electrical equipment.

While the impact of most of these events is limited, there is precedent for more catastrophic outcomes. In 1859, the Carrington Event, the most powerful solar storm ever recorded, knocked out telegraph lines across North America and Europe. In today’s highly electrified world, a similar event could cause between $2.4 and $3.4 trillion in damage to the power grid alone.

Now, researchers at Boston University and the University of Michigan have come up with a potential solution. In a paper published in Space Weather, they propose a constellation of satellites called StormWall that would release hundreds of tons of gas into orbit to blunt the force of an incoming solar storm.

“It’s as if you could install an airbag in the magnetosphere,” co-author Daniel Welling, a space physicist from the University of Michigan, told Science.

Solar storms have the potential to sow chaos because they weaken the magnetic shield protecting Earth from space radiation. Powerful enough storms disrupt the Earth’s magnetic field and cause it to reconnect to the sun’s, allowing energy from the solar storm to pour into the magnetosphere.

The Earth already has a natural defense against this—a doughnut-shaped reservoir of ionized gas, or plasma, sitting just above the atmosphere. When the planet’s magnetic field is disturbed, a plume of this plasma flows toward the sun and slows the rate at which the magnetic fields reconnect.

StormWall would turbocharge this process by releasing massive amounts of artificial plasma into the outer atmosphere. The researchers sketch out a system involving a constellation of satellites orbiting about 22,000 miles from Earth. The satellites would carry canisters of lithium, barium, or sodium gases to be ejected when a large solar storm is inbound. The gases, rapidly ionized by solar radiation, would add to the planet’s natural plasma shield.

Based on simulations, the researchers estimate that releasing around 400 tons of gas could reduce the strength of a major geomagnetic storm by over 50 percent. Crucially, the intervention would be swift and reversible. The plasma cloud could be in position by the time a storm hits, and it would dissipate just a few hours later.

Launching this much material into orbit would be a big undertaking, but the researchers say it could be within reach of emerging heavy-lift vehicles like SpaceX’s Starship or China’s Long March 9 rocket. They calculate that six launches could deploy the full constellation in under two months.

Outside experts have been broadly positive. Allison Jaynes, a space physicist at the University of Iowa, told Science the idea was “highly innovative and appears to be quite feasible in the near term.”

But getting the satellites into orbit is only part of the puzzle. Accurate and timely space weather forecasts would also be a prerequisite. And gaining international buy-in for a system that would drastically alter the near-Earth space environment, even if only temporarily, could be challenging.

The researchers flag potential side effects that need more study, including the generation of electromagnetic waves as the released material ionizes. Still, given the devastation a Carrington-sized event could unleash on the modern world, the potential downsides may be worth the risk.

There were several key components to emerge from Apple’s developer conference Monday as the company sought to reassure users (and investors) that it has met the existential challenge represented by AI. Aside from a serious focus on Siri AI and embedded Apple Intelligence across its varied platforms, officials also hailed a slew of performance/usability tweaks, described new child safety tools, gave macOS 27 a real name, “Golden Gate” — and offered a standing ovation in farewell to outgoing CEO Tim Cook.

Before the Worldwide Developer Conference (WWDC), analysts seemed optimistic about the company’s plans, most of which had already leaked. Analysts didn’t expect Apple to announce anything that would transform the AI industry (it didn’t), but they did hope the company would introduce tools to keep it competitive with rivals (it did). That’s assuming all the demos at the event were live, actual feature demos, rather than faked set-ups as seen before.

Hard, hard work

Apple’s teams have evidently worked incredibly hard to come this far, and execs did introduce truly impressive new AI features focused on what customers and developers actually need. The company also played to its strengths, particularly around vision intelligence; private-by-design (large language models) LLMs; highly useful contextual awareness; and Siri AI, which works as an app and lets you carry on conversational quests securely across all your Apple devices.

As anticipated, Apple also introduced APIs developers will be able to use to provide new AI features in their apps.

Among the many individual tools most of us can expect to use this fall, are:

• Siri AI, which can help users search for information across their messages, emails, photos, and more; answer questions about virtually any topic; and take action in apps. 
• Apple Passwords, which now automatically fix weak and compromised passwords with agentic AI.
• Spatial reframing, which lets users recompose a photo after it’s been taken by dragging to shift perspective, as if repositioning the camera in the original scene.
• A new Extend Tool, which expands the edges of an image to add breathing room, fix a crooked horizon, or change aspect ratio without losing the original subject.
• A Notify Me tool that monitors web pages for changes such as price drops or restocks and sends a notification when something changes.
• Photorealistic image generation, which supports the creation of high-quality photo-realistic images via a new generative model running on Private Cloud Compute.
• One-tap contextual suggestions in Messages, which surface actions such as creating reminders and notes, or finding relevant photos based on conversation context.
• And Describe a Shortcut, which means users can describe an automation they want in plain language and Shortcuts assembles the required steps automatically.

All about you, not AI

Apple did not seek to introduce AI features for their own sake; instead, it remains deeply focused on how to make its devices more useful to customers. As Craig Federighi, Apple’s senior vice president of software engineering, said: 

“Truly helpful AI must be centered on our users’ needs, deeply integrated into the products they rely on every day, grounded in personal context, and built with privacy at every step. That is our vision for Apple Intelligence. With useful features for browsing the web, expressing creativity, editing photos, and so much more, today marks a big step forward on our journey to integrate powerful AI into the core of our platforms and make our products even more personal and useful.”

Apple is not Gemini

Apple confirmed that it worked with Google Gemini to create some of the AI models highlighted today. This led some analysts before the event to say: “For Apple, the bull case is that a working Siri reframes it as an AI winner; the bear case is that paying a rival for core intelligence caps the premium investors assign to the stock.”

Perhaps they need not worry, as what we now seem to have is a far more solid base from which to continue to develop AI services and tools that compete against others in the space. Not only that, but Apple is not using rebranded Gemini — it simply worked with Google to build its own models, as Federighi insisted. In meetings at the show, Apple explained the full extent of the work it did with Google, stressing that none of the new features should be considered white label versions of Google’s LLMs. 

(Even Apple’s new search tools are based on its own search database, rather than anybody else’s. And when advanced searches are shared with Google-hosted Nvidia processors, Apple puts privacy protection in place.)

In the end, the most important consideration — for customers and developers — is that Apple seems to have succeeded in bringing dozens and dozens of powerful new on-device AI tools to its customers, giving it a firmer, more impressive peer position in the business. (It’s also true that investors were disappointed that the new AI features won’t be made available in Europe or China due to regulatory challenges, putting developers in both nations at a disadvantage.) Developers elsewhere will be able to explore Apple’s Foundation Models and its new Core AI APIs to their heart’s content. 

First reactions to Apple’s news

While Apple’s stock value dipped as investors sold on the news and invested into the speculation, I do think Apple successfully turned this corner — though it will need to continue to invest heavily in AI across its platforms. The work is far from over.

“It is great to see Apple continue to pursue a vision of AI that leverages local systems, preserves privacy, and integrates with third party tools,” Ken Case, CEO of the Omni Group, told me. “A lot of our work around the Apple Foundation Models and automation, App Intents, and adopting Swift look to be fruitful investments, but it’s clear there’s more to do starting this summer.”

Creative Strategies President and Principal Analyst Carolina Milanesi explained why it matters Apple is deploying these capabilities across its ecosystem, as it gives the company a unique market position. “Where Apple Intelligence is today is different than what Claude or ChatGPT are because is it really embedded in the devices, and we need to remember that Apple sells devices,” she said.

Apple did also note that the new Siri AI will be available in beta this year. “Investors wanted it in September. That means the real version is likely early to mid 2027,” said Gene Munster at Deepwater Asset Management. “Funny that the stock actually ticked up 0.5% on the “beta later this year” update given [that] while it’s later than what they wanted, it is at least a date that investors can focus on.”

It is also true that what Apple did achieve this year at WWDC is to offer up a set of new AI features that investors already see as having significant value.

Dozens of cryptographically verified open source packages from Microsoft were compromised late last week to add advanced credential-stealing code that was triggered when developers opened them in AI coding agents.

In all, multiple researchers said, 73 packages were flagged as malicious when automated systems on GitHub blocked them on the platform. Rather than noting they are malicious—and that developers who used AI agents to work with them should assume their systems are compromised—the Microsoft-owned GitHub said it disabled the packages “due to a violation of GitHub's terms of service.” The text went on to encourage the package owner to contact GitHub.

Devs: Assume compromise and proceed accordingly

It wasn’t until Monday that Microsoft even raised the possibility the packages were infected. In an email, the company stated: “We have temporarily removed some repositories as we investigate potential malicious content.”

Check Point released an emergency fix on Monday for a critical authentication bypass vulnerability affecting its Remote Access VPN and Mobile Access deployments - but attackers, including ransomware criminals, got a month-long head start. Attacks against the bug, tracked as CVE-2026-50751, began on May 7, according to Check Point VP of research Lotem Finkelstein, and picked up in early June. The security software vendor spotted suspicious activity and began investigating the zero-day on June 4, Finkelstein said in a Monday blog. “We have observed indications that exploitation has been limited to a relatively small number of targeted organizations (several dozen globally), primarily over the past few days,” Finkelstein wrote, adding that, in at least one case, investigators observed post-compromise activity associated with a Qilin ransomware affiliate. This same ransomware scum is also likely exploiting other VPN-related vulnerabilities in Palo Alto Networks, Fortinet, and F5 products, Finkelstein said. CVE-2026-50751 is due to a logic-flow weakness in the Remote Access and Mobile Access certificate validation process, and it allows remote attackers to bypass authentication and establish a remote access VPN connection without a user password. It affects Mobile Access/SSL VPNs, Remote Access VPNs, and Spark Firewalls configured to use the deprecated IKEv1 key exchange protocol. While investigating CVE-2026-50751 and affected VPN components, Check Point found another vulnerability, CVE-2026-50752, in its Security Gateways and Spark Firewall products. It’s due to a bug in the certificate validation logic of the deprecated IKEv1 key exchange method, and can lead to man-in-the-middle attacks on the VPN site-to-site configuration. Check Point says that it hasn’t received any reports of in-the-wild exploitation of CVE-2026-50752. Check Point urges customers running vulnerable gateways and firewalls to apply the hotfixes, and the vendor also provided alternative mitigation options with instructions in the security advisories. The software provider also published a list of indicators of compromise, including attacker IPs, and recommends customers search Check Point SmartConsole logs for possible VPN certificate authentication attempts associated with observed attacker infrastructure and certificate subject names for at least May 7 through June 5. ®
