Posts claim that huge crowds, in the hundreds of thousands, have filled the Champs-Elysees in Paris to see Pope Leo XIV, with an atmosphere described as electric. A widely shared post from a Catholic-focused account says the turnout is unbelievable, and the clip or claim has drawn roughly 15,000 likes. The posts describe the scale of the crowd but do not explain what the Pope is in Paris for, so the exact occasion is not clear from the evidence.
- 2Satellite Engine That Breathes Earth's Atmosphere Proposed●New Satellite Engine Could Use Earth's Atmosphere to Stay in Orbit Indefinitely
Researchers have unveiled a concept for an air-breathing satellite engine that scoops up molecules of Earth's upper atmosphere and uses them as propellant, allowing spacecraft in very low orbit to refuel themselves and stay aloft indefinitely without carrying finite fuel. If proven, the design could enable long-lived Earth observation satellites and new very-low-orbit missions that today decay and burn up within months.
- 3Satellite data reveals boom-and-bust cycles in greening drylands▼Satellite data exposes escalating 'boom-and-bust' dynamic in greening drylands
Researchers at the University of Arizona report that satellite observations show drylands worldwide are greening, but in an increasingly volatile 'boom-and-bust' pattern: bursts of vegetation growth are followed by sharp crashes. The study suggests that rising atmospheric carbon dioxide is fuelling plant growth in arid regions, yet this greening masks growing instability, with vegetation swings becoming more extreme over time.

Paramount has won the bidding for Warner Bros., a deal that will put CNN under new ownership. According to a Variety report, staff inside the news network describe the atmosphere as 'like a funeral', with the path forward described as hazy. Employees are anxious about what Paramount's takeover will mean for CNN's editorial direction, leadership and staffing as one of America's best-known cable news operations changes hands.
- 5Astronomer turns sinking Starlink satellites into planetary barometer●Astronomer watches Starlink satellites sinking to build a 'planetary barometer'
An astronomer is tracking how Starlink satellites gradually sink in their orbits and using that data as a 'planetary barometer' to measure conditions in Earth's upper atmosphere. The idea is that changes in satellite orbital decay reveal atmospheric density, offering a novel scientific use for the thousands of SpaceX satellites in low Earth orbit.

An Irish footballer, after scoring against Israel, kissed a black armband worn in tribute to Palestinians killed in Gaza. The gesture, shared widely on social media, has drawn attention as a visible show of solidarity amid the ongoing war and the charged atmosphere surrounding matches against Israeli teams.
- 7Why AI struggles to forecast hurricane intensity●Why AI has trouble predicting the fury of hurricane intensity
AI-based forecasting has improved hurricane track predictions, but rapid intensification remains difficult to model. Phys.org reports that machine learning systems have trouble capturing the small-scale ocean and atmosphere processes that drive a storm's sudden surge in strength, which is often the most dangerous element for coastal communities. Forecasters say intensity errors can leave residents with little time to prepare.
- 8Earth's atmosphere has gotten less dusty in unexplained reversal●In a mysterious reversal, Earth’s atmosphere has gotten less dusty
Scientists have observed that the amount of dust in Earth's atmosphere has declined, reversing a previous trend. NBC News reports the shift is described as mysterious, with the cause of the reversal not yet explained. Dust in the atmosphere affects climate, air quality and weather patterns, so researchers are paying close attention to what is driving the change.
- 9MicroWatt launches first UL certified inspection robot for hazardous sites▼MicroWatt Launches North America’s First UL Certified Inspection Robot for Hazardous Locations
Canadian robotics firm MicroWatt has launched North America's first UL certified inspection robot designed for hazardous locations, such as oil, gas and chemical facilities. The certification means the robot meets strict safety standards for operating in explosive or flammable atmospheres, allowing companies to automate inspections in zones previously off-limits to robotics. Industry coverage highlights it as a milestone for industrial automation in energy and petrochemical sectors.
- 10Private spacecraft burns up after failed NASA telescope rescue●Private spacecraft burns up in Earth's atmosphere after failing to rescue aging NASA telescope
A private spacecraft has burned up in Earth's atmosphere after a mission to rescue an aging NASA telescope failed. The craft, sent to service or retrieve the telescope, did not complete its task and was destroyed on reentry. The failed effort raises questions about the fate of the decades-old observatory it was meant to save.
