The deployment of reflective mirrors on satellites and the launch of thousands more satellites into low Earth orbit could have significant consequences for human health and ecosystems. Leading sleep and circadian rhythm researchers have raised concerns about the potential disruption to natural night-time light environments.The US Federal Communications Commission (FCC) is considering plans by Reflect Orbital to illuminate parts of the Earth at night using reflective satellites, as well as applications from SpaceX that could dramatically expand satellite numbers in low Earth orbit.2,500 researchers from over 30 countries have expressed concerns that altering the light-dark cycle could disrupt biological clocks that regulate sleep and hormone secretion in humans and animals, migration in nocturnal species, seasonal cycles in plants, and the rhythms of marine phytoplankton.Prof Charalambos Kyriacou, president of the European Biological Rhythms Society (EBRS), emphasized that "plants need the night" and that eliminating it could have global implications for food security.Reflect Orbital aims to use satellites equipped with large reflective mirrors to redirect sunlight onto areas roughly 5km to 6km wide "on demand", with brightness adjustable "from full moon to full noon".Meanwhile, SpaceX has proposed launching up to 1m satellites to create a giant solar-powered computing network in orbit designed to run artificial-intelligence workloads.Ruskin Hartley, chief executive of DarkSky International, noted that scientific studies have already shown that the existing number of satellites in orbit has increased diffuse night sky brightness by roughly 10%.Experts warn that if current trends in satellite launches and debris generation continue, night sky brightness could increase substantially over the coming decade, approaching the threshold astronomers have set for preserving naturally dark skies.

The inaugural match at Inter Miami’s brand‑new Nu Stadium ended in a 2‑2 stalemate with Austin FC, but the event was a triumph for co‑owner Sir David Beckham, whose 13‑year odyssey to secure a flagship MLS venue finally reached its destination.Speaking before kickoff, Beckham reflected on his arrival in the United States two decades ago, recalling a promise to build a club that could win championships and grow the sport. “We had no name, no fans, no stadium – today we stand in our new home,” he declared to a sold‑out crowd.The stadium, a sleek bowl with a 26,700‑seat capacity and an overhanging oval canopy, blends Miami’s vibrant aesthetic – pink, white and black seats, neon lighting – with a design that keeps the atmosphere intimate despite its size. Fans were treated to a clear view of the action, and a standing section behind one goal preserved the club’s traditional, vocal support.On the pitch, Argentine legend Lionel Messi and Uruguay’s Luis Suárez each netted equalising goals, while Austin’s Guilherme Biro etched his name in MLS history as the first scorer at the venue with a sixth‑minute header. Messi’s 90th‑minute free‑kick rattled the crossbar, and Suárez’s late volley secured a point for the home side.Beyond the match, the night highlighted the stadium’s broader significance. The $1 billion development, approved in 2022, will eventually encompass a 58‑acre public park, retail, office space and a 750‑room hotel complex. Though much of the surrounding site remains under construction, the opening demonstrated that the project met its tight deadline, even as officials chased a final occupancy certificate hours before kickoff.MLS Commissioner Don Garber praised Beckham’s perseverance, noting that the journey “didn’t end when Messi arrived; it concluded with the opening of this building.” He added that the rapid progress in the final month exceeded expectations and underscored the importance of trust in ambitious projects.The event also featured a performance of the national anthem by Marc Anthony and a rally‑towel message reading “We’re home,” encapsulating the relief and pride of supporters who have long awaited a true Miami‑based home after years of travelling to Fort Lauderdale.While the match did not deliver a win, the successful launch of Nu Stadium represents a pivotal moment for Inter Miami, its ownership group, and the broader growth of soccer in South Florida.

Nasa administrator Jared Isaacman has stated that the possibility of alien life is a crucial factor in planning the agency's space missions. In a recent interview with CNN's Meet the Press, Isaacman emphasized that investigating the existence of alien life 'goes to the heart of many things that we do at Nasa.'Isaacman's comments come as Nasa's Artemis mission to circumnavigate the moon is underway, marking the first lunar mission since 1972. The mission aims to explore the moon's far side and could potentially lay the groundwork for a moon base on the south pole, equipped with telescopes to aid in the search for extraterrestrial life.While acknowledging that he has not encountered any aliens during his own space travels, Isaacman expressed optimism about the likelihood of discovering life elsewhere in the universe. 'With 2 trillion galaxies out there, who knows how many star systems within each of them? I would say the odds that we will find something at some point to suggest that we are not alone are pretty high,' he said.The Artemis mission has also faced challenges, including a malfunctioning $30 million toilet on the Orion spacecraft. However, Isaacman assured that the issue has been addressed, and the crew is prepared for any eventuality.

The historic Artemis II mission is on track to reach the far side of the moon on Monday, with NASA reporting satisfaction with the progress made since the team's launch on Wednesday. The crew, comprising three Americans and one Canadian, will break the record for maximum range from Earth.The astronauts, Victor Glover, Christina Koch, Reid Wiseman, and Jeremy Hansen, are the first to bound for the moon in over half a century, picking up where the Apollo program left off in 1972. The mission aims to establish a permanent lunar base, with NASA targeting a landing by two crew members near the lunar south pole in 2028.During their journey, the crew has reported persistent issues with the Orion capsule's toilet, which has been malfunctioning since liftoff. Despite this, morale remains high, with the astronauts describing their experiences and sharing images of the moon's surface.The next significant milestone is expected overnight Sunday into Monday, when the astronauts will enter the lunar sphere of influence, where the moon's gravity will have a stronger pull on the spacecraft than Earth's. If successful, the Artemis II crew will have traveled further from Earth than any human before.The mission promises breathtaking views of the moon's far side, which was too dark or difficult to see for the 24 Apollo astronauts who preceded them. The crew will observe the celestial body with their naked eyes and cameras onboard during the flyby, which will last approximately six hours.

NASA has unveiled a series of photographs documenting the Orion spacecraft as it reaches the four‑day mark of the Artemis II mission.The images, released by the agency, capture key phases of the flight, offering a visual update on the vehicle’s trajectory and system performance as it continues its historic test flight around the Moon.While the photo set provides a rare glimpse into the mission’s progress, NASA has not disclosed additional technical details beyond the visual record at this stage.

When Corentin Roudaut arrived in Paris a decade ago, he swapped his student‑era bike for a car, daunted by the city’s traffic and lack of cyclist protection. After a protected lane opened on Boulevard Voltaire in the 11th arrondissement, he reclaimed his two‑wheel commute and now volunteers with the cycling advocacy group Paris en Selle, witnessing a city that has shed its car‑centric image.Roudaut notes that the shift “started slowly but really accelerated in the last ten years,” with a growing network of bike routes that is becoming safe and nearly complete in many districts.Mayor Anne Hidalgo’s 12‑year agenda reshaped Paris’s urban fabric. Since taking office in 2014, her administration planted 155,000 trees, created several hundred kilometres of segregated bike lanes, pedestrianised 300 school streets, and banned cars from the banks of the Seine. Former parking spaces have been turned into green plazas and café terraces, reducing the risk of children being hit while walking to school.As Hidalgo departs on Sunday, her legacy is touted as a blueprint for progressive European cities, especially as some national governments retreat from green initiatives.Nevertheless, the reforms have sparked pushback. Motorists object to the loss of road space, and recent referendums on higher parking charges for SUVs and further school‑street pedestrianisation suffered low voter turnouts. Right‑wing mayoral candidate Rachida Dati described the new public‑space regime as “anxiety‑inducing,” though she stopped short of promising a reversal.In a candid interview, Hidalgo described the Seine‑bank pedestrianisation as “a tough battle” that, once won, left residents reluctant to revert to car traffic. She highlighted a generation of children who have never known cars on those riverbanks, prompting awe‑filled reactions from visitors.Urban scholars attribute the rapid change to Paris’s tight administrative boundaries, which limit suburban influence on city transport decisions, and to groundwork laid by previous mayors. Yet they stress that political courage was essential to implement measures that inconvenienced drivers while delivering social and environmental benefits.Environmental epidemiologist Audrey de Nazelle of Imperial College London, a Paris native, praised the transformation as “fabulous” and warned that many cities lack the bravery to pursue similar legacies.A recent report placed Paris among 19 global cities that cut two major toxic air pollutants between 2010 and 2024. While Brussels and Warsaw saw faster declines in fine‑particle matter, London outpaced Paris in reducing nitrogen‑dioxide levels.By contrast, Berlin—despite opening a new inner‑city motorway and scrapping 30 km/h speed limits on key streets—still records a higher share of cyclists than Paris.Transport researcher Giulio Mattioli argues that Paris simply needed to add bike lanes to unlock latent demand, noting that the city started from a lower baseline but quickly caught up with peers.However, the transformation remains uneven. The extensive suburbs continue to be dominated by cars, hemmed in by the 35 km Boulevard Périphérique ring road. Analyst Jean‑Louis Missika of think‑tank Terra Nova stresses that “as long as this motorway encircles Paris, the Greater Paris metropolis will remain an administrative construct devoid of urban reality.” He calls for dismantling or repurposing the ring road to achieve a truly post‑car metropolis.

NASA has unveiled the first photographs taken from inside the Artemis II Orion spacecraft, where a crew of four astronauts is currently circling the Moon. The images, released on Friday, were captured by mission commander Reid Wiseman through the capsule’s window, revealing a cloud‑shrouded Earth rising beyond the spacecraft. A second shot displays the full globe, complete with shimmering oceans and a faint green aurora, emphasizing the planet’s fragility from deep space. At mid‑morning on Friday, the crew was approximately 100,000 miles (160,000 km) from Earth and had another 160,000 miles (258,000 km) to travel before reaching the Moon, a milestone expected on Monday. The team—three Americans and one Canadian—will orbit the Moon in the Orion capsule before looping back to Earth without landing. The spacecraft entered its lunar trajectory after firing its main engine on Thursday night. Mission specialist Christina Koch, the first woman to travel around the Moon, told ABC News, "I knew that is what we would see, but nothing prepares you for the breathtaking view of our home planet lit up by day and the Moon’s glow at night." She added that the crew is eager to experience similar vistas of the Moon and the eventual return home. The mission is now on its third day of a planned ten‑day flight. On day six, the Orion will make its closest approach to the lunar surface, passing 4,000‑6,000 miles (6,450‑9,650 km) above the Moon. After circling the far side—the first human deep‑space journey of this magnitude in over five decades—the crew will use lunar gravity to set a course back to Earth, with a splashdown slated for April 11 at 00:06 GMT (8:06 p.m. ET on April 10) in the Pacific Ocean off San Diego. Astronaut Victor Glover reflected on the emotional impact of seeing Earth from space, saying, "From up here, you look amazing. Homo sapiens is all of us—no matter where you’re from or what you look like. We’re all one people." He called the mission a true "moonshot" that demonstrates what humanity can achieve when differences are set aside. The released images not only showcase the technical success of Artemis II but also serve as a powerful reminder of our shared planetary identity as the crew prepares for the historic lunar flyby.

Iranian officials have asserted that they successfully downed two United States warplanes in separate incidents. The first aircraft was reported to have been shot down over Kohgiluyeh and Boyer-Ahmad province, while the second went down in the Gulf region. According to Tehran’s statements, two U.S. crew members have been rescued, but at least one airman is still unaccounted for. The incident, confirmed by Iranian sources, is being presented as evidence of the country’s advancing air defense capabilities and its resolve to protect sovereign airspace. The downing of the aircraft arrives amid already strained U.S.-Iran relations, raising concerns about potential escalation. Analysts note that such incidents could prompt diplomatic protests, affect regional security calculations, and influence the operational posture of U.S. forces stationed in the Middle East. While the exact models of the downed warplanes have not been disclosed, the events underscore a broader narrative of increasing military assertiveness in the region. The loss of a U.S. crew member, if confirmed, would add a human dimension to the geopolitical fallout, potentially prompting calls for heightened caution on both sides. International observers are monitoring the situation closely, as the incident may impact ongoing negotiations, trade routes through the Gulf, and the strategic balance between regional powers.

On a sun‑lit picnic beside Canberra’s Molonglo River, a tartan blanket, a bottle of wine, crusty baguette, cheese and a daring chicken‑and‑grape salad from a gourmet magazine marked the beginning of a romance that would be defined by food.Their shared appetite for culinary experimentation quickly turned into a series of kitchen showdowns—debates over meat doneness, oven temperatures, seasoning ratios and the eternal butter‑vs‑oil dilemma. While the clashes were frequent, the meals they produced together often became celebrated triumphs.Over the years, their lives were chronicled in the spines of recipe books and the aromas of countless dinners.
