Rocky Planet Has an Atmosphere — and Solar Storms May Have No Upper Limit

Astronomers using the James Webb Space Telescope have confirmed the first atmosphere on a rocky planet inside the habitable zone of another star. The planet, LHS 1140b, is a super-Earth approximately forty-nine light-years away. What researchers detected specifically is helium escaping from the planet's atmosphere — helium escape serves as a tracer for a more substantial atmospheric envelope beneath it. A planet this size with a confirmed atmosphere in the right temperature zone could theoretically harbor liquid water on its surface. The finding challenges a prevailing hypothesis that small rocky planets orbiting red dwarf stars — the most common stellar type in the galaxy — would be stripped of their atmospheres by stellar radiation.

A NASA study released this week concluded that solar storms may have no theoretical upper limit in intensity. Extrapolating from the statistical distribution of known storm events, researchers found no ceiling on how powerful a coronal mass ejection could become. The Carrington Event of 1859, which disrupted telegraph systems globally, is the historical benchmark; a comparable event striking today's satellite networks, power grids, and internet infrastructure would produce effects orders of magnitude more severe. Researchers characterized space weather hardening of critical infrastructure as a genuine national security priority.

Stanford aging researchers demonstrated that inhibiting the EP2 receptor on macrophages — specialized immune cells — restored the body's ability to clear senescent cells, the so-called 'zombie cells' that accumulate with age and contribute to inflammation, frailty, and cognitive decline. The experiment worked in older mice, reducing measurable markers of aging. The leap from mouse models to human therapies is long and uncertain, but the clean biological mechanism — targeting a specific receptor to restore a natural cellular process — is the kind of target that researchers say tends to translate better across species than more complex interventions.

Researchers using Quantinuum's fifty-four-qubit processor demonstrated non-Abelian anyons — exotic quasiparticles with a property called topological protection that exist only in two-dimensional systems. The significance lies in architecture: topological quantum computing is theoretically far more resistant to the decoherence errors that plague conventional quantum computers. Demonstrating a complete universal gate set using this approach on real hardware rather than simulation is described as a meaningful step toward practically reliable quantum systems.

A separate climate study confirmed that U.S. rain now originates from farther away geographically than historical averages — a subtle finding with real infrastructure consequences. Precipitation traveling longer atmospheric distances before falling tends to arrive in different seasonal patterns and intensities. Water managers design reservoirs, aqueducts, and flood control systems around historical precipitation norms; if those patterns have shifted systematically, the engineering assumptions embedded in decades of infrastructure may be increasingly misaligned with actual conditions.
