The European Space Agency (ESA) together with NASA is gearing up for the launch of the Solar Orbiter spacecraft a 3,975-lb. (1,800 kg) sun-observing satellite.

Designed to study the sun up close, Solar Orbiter will take the first photos of the sun’s pole as well as provide scientists with crucial data to help guarantee against space weather.

Most of us look up at the sun and think of it as just a glowing orb in the sky, bathing the Earth in light, but our star has a darker, violent side. (Please do not stare directly at the sun, only Solar Orbiter is equipped to do so. Here are some safe ways to look at our host star.)

The sun regularly produces massive solar flares, which erupt on its surface, spewing X-rays and high-energy particles everywhere. Just eight minutes after the violent outburst, those same X-rays can slam into the Earth’s magnetic field. Most of the time, our protective shield keeps us protected from the sun, but it can be overwhelmed at times.

High energy particles from the sun run along magnetic field lines, like electric currents run through wires, looking for a release. Most often we see the lighter side of the sun’s wrath, in the form of auroras.

But really powerful ones can cripple communication systems and power grids. Radio signals, like the ones we use to communicate, are able to travel great distances through a section of the atmosphere known as the ionosphere. However, when a powerful solar storm is raging, those signals are cut off by the X-rays emitted by the sun and are ultimately drowned out by crackling static.

A recent study, published in the journal Geophysical Research Letters, indicates that the most powerful solar storms can hit once every 25 years, with less intense ones battering the Earth about once every three years.

The team, led by Dr. S.C. Chapman from the University of Warwick, identifies two types of powerful magnetic storms: ‘great super storms’ and ‘severe super storms.’ These two types are both considered dangerous and capable of causing damage to our valuable infrastructure here on Earth.

Also called geomagnetic storms, these cosmic tempests are caused by disturbances inside the sun that send particles streaming out into space. When they slam against our planet’s magnetosphere, they generate space weather, which can be very catastrophic to our sensitive electronics and power grids.

The most famous of these solar storms occurred in 1859. The Carrington Event is the most powerful geomagnetic storm ever recorded. It knocked out telegraph systems around the world, started a few fires, and even shocked some of the telegraph operators.

In 1989, a similar outburst caused issues in Canada. In Quebec, the province’s power supply station was disrupted and incredible auroras filled the sky with light when a wave of solar particles came in contact with the Earth. People as far south as Texas could see the dazzling light display.

These disturbances look to be increasingly more common and can disrupt all sorts of technology from satellites to global communications systems and more.

The world relies heavily on satellites, which are incredibly vulnerable due to their sensitive parts. Scientists theorize that if a modern-day Carrington event were to happen, it could cost trillions of dollars worth of damages. This is why scientists are using spacecraft, like Solar Orbiter and its counterpart the Parker Solar Probe, to really understand the processes that are taking place.

Tesla to improve one of its best features, coding shows

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.

The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.

Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.

There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.

Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.

Tesla’s revolutionary Matrix headlights are coming to the U.S.

This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.

xAI’s Grok approved for Pentagon classified systems: report

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.

Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.

Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations. 

The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.

Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards. 

Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD. 

Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible. 

The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.

Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.

In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”

The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.

In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide. 

Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.

Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.

In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.
