Magnetic Wave Detection Uncovers Elusive Lithium in Mercury’s Thin Exosphere

Magnetic Wave Detection Uncovers Elusive Lithium in Mercury’s Thin Exosphere

Using a new technique based on magnetic-wave analysis, scientists have, for the first time, discovered lithium in the atmosphere of Mercury. Published in Nature Communications, the study constitutes the first detection of lithium around the smallest planet in our solar system. The exosphere of Mercury, Unlike thickened atmospheres, the thin shell of particles that constitutes Mercury’s exosphere can render direct searching methods inadequate. Instead of searching for atoms, scientists analysed pick-up ion cyclotron waves—an electromagnetic fingerprint left behind when solar wind interacts with freshly ionised lithium. These faint signals finally confirmed lithium’s long-speculated presence.

MESSENGER Data Reveals Lithium Traces from Meteoroid Impacts in Mercury’s Exosphere

As per the Austrian Academy of Sciences, the research team led by Daniel Schmid reviewed four years of magnetic field data collected by NASA’s MESSENGER spacecraft. Twelve short-lived events—each lasting mere minutes—revealed these lithium-specific wave signatures.

The waves are generated when solar ultraviolet radiation ionises lithium atoms, and temporary lithium wind blows the ionised atoms into space, which increases the speed of the formation of electromagnetic instabilities. These perturbations induce oscillations at a single cyclotron frequency, determined by the mass and charge of lithium (such that it is identified as lithium indirectly by magnetic measurements).

Lithium has been difficult to find, as the rare alkali metal is thinly scattered. The traditional particle detectors on Mariner 10 and MESSENGER couldn’t directly capture it. The most likely candidate is meteoroid impacts, which would cause heated vapour clouds in the collision and throw lithium into the exosphere.

Mercury’s surface is continuously replenished by extraterrestrial bombardment, according to a study linking detected events to meteoroid strikes by objects 13-21 centimetres in radius. These high-speed collisions can vaporise up to 150 times their own mass, endowing the atmosphere with volatiles such as lithium.

Schmid’s study reveals that such processes could also account for the retention or acquisition of volatile elements in other airless bodies, which would transform our understanding of the geochemical story of Mercury and open up new steps in exosphere exploration.

There’s many uncertainties in this world, but apparently the future of Prime Video’s Lord of the Rings: The Rings of Power may not be one of them.

According to a source speaking to The Ankler’s Lesley Goldberg, the show’s considered a “magical halo” by Amazon CEO Jeff Bezos. As such, it’s “proteced for its run” and likely to finish out the five-season arc Amazon pitched back when it first secured the rights. Getting those rights and making the show has been pretty pricey for the company, and the first two seasons had a two-year release gap. At time of writing, the show’s third season doesn’t have a firm date beyond “sometime in 2026,” and some have generally wondered how much more life Rings of Power had left in it.

Goldberg’s report also mentions a tradeoff to this five-season plan: for Rings of Power to live on, a spinoff that’d been planned for it has gotten axed. Major Prime Video shows like The Boys and Invincible have become small franchises unto themselves, and it makes sense the streamer would want to repeat that for its remaining big fantasy series. While Amazon may not get to build on Middle-earth after the show ends, Warner Bros. is determined to keep the Lord of the Rings train going with two new films: a Gollum prequel, and an interquel that also reunites the Hobbits after the events of Return of the King.

Apple Watches are smart little gadgets, but they don’t always fit the vibe. There were plenty of nights and dressier events when I left mine at home because—as much as I wanted to check my notifications discreetly—it didn’t match my outfit. I’ve also had my fair share of faux pas and just let the neon orange sport band clash with my neutral ensemble.

Fortunately, Apple Watch bands are a simple and relatively affordable way to zhuzh up the look of your wearable. Beyond aesthetics, different styles also impact performance and functionality. For example, I don’t want a heavy stainless steel or high-quality leather band weighing me down during a sweaty workout, just as I wouldn’t wear a flimsy silicone band to a dinner party.

At WIRED, we’ve been testing bands since the very first Apple Watch launched in 2015. After years of wearing and swapping, I’ve rounded up the best bands for every occasion. Be sure to check out our related product guides, including the Best Apple Watch Accessories, Best Apple Watch, and Best Smartwatches for more recommendations.

Best Band for Everyday Wear

The Nike Sport Loop has been my everyday band since 2020. I bought another in 2023 because I wanted to swap colors, and I figured after three years, I should buy a brand-new one, but it has held up remarkably well. Made from a blend of recycled polyester, spandex, and nylon, it’s breathable and lightweight. The double-layered nylon weave is designed with dense loops that help prevent moisture from getting trapped against your skin. As long as you regularly hand-wash it to rid it of sweat buildup and dirt, it stays odor-free.

The hook-and-loop fastener and pull tab make it easy to adjust with one hand. It is Velcro, so beware, it can snag on softer fabrics. Still, for a band designed with sports in mind, it’s understated enough to wear almost anywhere. I wouldn’t wear it to a formal event, but for the office or casual social events, it’s perfect.

Nomad originally designed the Stratos Band for the Apple Watch Ultra, but it fits just as well with the SE and Series 1 through 11. It’s easy to adjust, refined enough for the office, and backed by Grade 4 titanium hardware with a scratch-resistant DLC coating. FKM rubber links (PFA-free and antimicrobial, according to Nomad) add flexibility, durability, and water-resistance. The clasp is made with corrosion-resistant N52 magnets, which make it effortless to snap on, and it’s designed with a manual release button, so you don’t have to worry about it accidentally falling off. It’s technically suited for workouts and outdoor use, but it is a hefty band that I personally prefer for casual everyday wear.
