Meta’s Quest for Night‑Time Renewable Power via Space‑Based Infrared BeamsIn a bold move to decouple data‑center operations from the limits of daylight, Meta signed a capacity‑reservation deal with Overview Energy. The agreement envisions a constellation of satellites that will transmit infrared light to terrestrial solar farms, enabling continuous renewable generation for AI‑heavy workloads.Overview Energy’s Satellite‑to‑Solar‑Farm Infrared Transmission PlanOverview, a four‑year‑old venture out of Ashburn, Virginia, proposes to harvest solar energy in orbit, convert it to near‑infrared, and beam it to large‑scale solar installations (hundreds of megawatts). Unlike high‑power laser or microwave concepts, the wide infrared beam is claimed to be safe for direct observation.Spacecraft collect solar power in low Earth orbit.Energy is converted to infrared and directed at ground‑based solar farms.Initial satellite launch slated for January 2028, with full deployment targeted for 2030.Scale of Meta’s Energy Use and the 1‑GW Capacity ReservationIn 2024, Meta’s data centers consumed more than 18,000 gigawatt‑hours of electricity—enough to power 1.7 million American homes for a year. The company has pledged to build 30 gigawatts of renewable capacity, focusing on industrial‑scale solar. Under the new contract, Meta can draw up to 1 gigawatt of power from Overview’s satellite fleet, measured in a novel unit called “megawatt photons.”Potential Disruption to Data‑Center Energy Models and Regulatory LandscapeBy beaming power directly to existing solar farms, Overview aims to sidestep the costly battery storage and grid‑integration challenges that currently limit night‑time solar use. If successful, the model could:Boost return on investment for solar‑farm owners.Reduce reliance on fossil‑fuel peaker plants.Introduce a new regulatory category for space‑to‑ground infrared transmission.CEO Marc Berte emphasizes that the beam is safe to look at, potentially easing public‑safety concerns that have hampered laser‑based proposals.Roadmap to 1,000 Satellites and What It Means for the Future of Renewable PowerOverview plans to launch 1,000 spacecraft into geosynchronous orbit, each with a design life of over ten years. Once a third of the planet is covered, the constellation could illuminate solar farms from the West Coast of the United States to Western Europe as the Earth rotates, delivering power precisely when it is most needed.2028: First satellite test flight.2030: Commence deployment of the full fleet.Long‑term: Enable flexible, on‑demand renewable power for global data‑center clusters.Should the technology scale, it may set a precedent for other high‑compute firms seeking sustainable, 24/7 power, and could spark a new market for space‑based energy services.

The northern hemisphere is currently treated to a spectacular view of the constellation Leo, dominating the spring night sky. The Sickle Asterism and Regulus Leo is most easily identified by its distinctive "backwards" question mark, referred to by astronomers as the "sickle" asterism and representing the head of the lion. The constellation's brightest star is Regulus, a brilliant blue-white star that sits almost exactly on the ecliptic, the path traced by the sun, moon and planets across the sky. Historical and Astronomical Significance Antiquity: Recognized since antiquity, it is one of the original 48 constellations listed by Ptolemy in the second century. Star Data: Regulus' position on the ecliptic makes it a critical marker for tracking planetary movements. Visibility: While visible from the southern hemisphere in the northern sky, it is currently the dominant feature in the northern hemisphere's spring evenings. Cultural Legacy Across Civilizations The constellation has a rich mythological tradition that spans thousands of years. In Mesopotamia, it was associated with the lion ridden by the goddess Ishtar, while the ancient Egyptians linked it to the annual flooding of the Nile River, which occurred when the sun passed through this region of the sky. Best Viewing Times for 2026 For optimal viewing, look high in the southern sky. The chart shows the view looking high in the southern sky from London on 27 April at 22:00 BST, although the view will be essentially the same all week.

Lead: A Guardian Country Diary entry captures a crisp Northumberland morning where hares, pheasants and migrating fieldfares share the landscape with an increasingly crowded night sky, now home to roughly 15,000 satellites, including Elon Musk's Starlink constellation.Morning on Alnwick Moor: Wildlife Meets HistoryThe red sun rises over the radar station, illuminating a hare, a pheasant and a red‑legged partridge—species re‑introduced by gamekeepers and native wildlife that have roamed Britain since Roman times. The nearby Roman road network, still evident in the straight, well‑kept lanes, reminds us of the region’s ancient connections.Satellite Surge: 15,000 Objects Crowding the Night SkyAt any moment, dozens of bright dots race across the heavens, disrupting the traditional constellations. Current estimates place the total in orbit at about 15,000 satellites, a figure that has risen sharply in the past five years.Starlink fleet: >3,000 operational satellitesOther commercial constellations: ~5,000 satellitesGovernment and scientific satellites: ~2,000Dark Sky Parks Under Threat: Light Pollution and Satellite GlareThe Northumberland International Dark Sky Park, renowned for its crystal‑clear night views, now faces dual pressures: ground‑based light pollution and the reflective glare of low‑orbit satellites, which can obscure faint stars and affect astronomical research.Future of Rural Nightscapes: Balancing Connectivity and ConservationAs demand for global broadband grows, policymakers must weigh rural connectivity benefits against the loss of pristine night skies. Potential solutions include stricter orbital altitude regulations, satellite de‑orbiting plans, and community‑led dark‑sky initiatives.

The Lyrid meteor shower, active since 16 April, reaches its zenith on the late evening of Wednesday 22 April and the early hours of Thursday 23 April, providing a spectacular display for sky‑watchers across the northern hemisphere. The Lyrid Meteor Shower Peaks This Week Viewing from London, the radiant sits in the constellation Lyra, near the bright star Vega. At 00:01 BST on 23 April the radiant will be visible low in the east, with meteors fanning out in all directions. Viewing Numbers and Timing Maximum rate: ~18 meteors per hour Peak window: late evening of 22 April through the early morning of 23 April Optimal viewing: after midnight, once eyes have adapted for 20‑30 minutes Why the Lyrids Matter to Astronomers Records of the Lyrids date back to 687 BC. Modern science links the shower to comet Thatcher, discovered in 1861. The meteoroids are remnants of the comet’s dust tail, offering a natural laboratory for studying cometary material and atmospheric entry dynamics. What to Expect for Future Lyrid Observations Because the radiant lies low in the northern sky, observers in the southern hemisphere will see a truncated display. In upcoming years, the shower’s intensity is expected to remain steady, but variations in comet Thatcher’s orbit could alter peak rates, making each season a unique observation opportunity.

Amazon disclosed on Tuesday that it will acquire satellite operator Globalstar for $11.57 billion, a strategic step to expand its fledgling Kuiper broadband system and directly confront Elon Musk’s Starlink network. The transaction grants Amazon immediate control of Globalstar’s low‑Earth‑orbit constellation of roughly two dozen satellites, bolstering a platform that currently competes with Starlink’s fleet of about 10,000 satellites in orbit. Under the agreement, Globalstar shareholders may elect to receive either $90 in cash per share or 0.3210 shares of Amazon common stock for each share they own. Amazon aims to launch about 3,200 Kuiper satellites by 2029, with roughly half required to be operational by the July 2026 regulatory deadline. The company already manages a network of more than 200 satellites and plans to roll out its satellite‑internet service later this year. In contrast, Starlink presently serves over 9 million customers worldwide. Louisiana‑based Globalstar, known for powering Apple’s “Emergency SOS” feature, operates the current constellation and expects to expand to 54 satellites under an Apple‑backed development program that includes a few backup units. Beyond voice and data, Globalstar provides asset‑tracking solutions to enterprise, government and consumer markets. Simultaneously, Apple—having invested roughly $1.5 billion in Globalstar—has signed an agreement with Amazon to continue supporting satellite‑based safety functions such as Emergency SOS and Find My for iPhone and Apple Watch users. The acquisition is slated to close in 2027, subject to regulatory approval and the achievement of specific satellite‑deployment milestones by Globalstar.

As the northern hemisphere welcomes spring, the constellation of Boötes, the herdsman, is rising to prominence in the eastern sky after dusk. This celestial display is a treat for stargazers, with the constellation's brightest star, Arcturus, shining brightly.A chart showing the view looking east from London at 21:00 BST on 6 April illustrates the optimal viewing conditions. By this time, the darkness is complete, and Arcturus, the fourth-brightest star in the night sky, is easily visible.To locate Boötes, start with the familiar shape of the Plough and follow the curve of its handle downwards in an arc until you reach the orange glow of Arcturus. This method makes it easy to find the constellation in the night sky.Boötes is one of the original 48 constellations defined by Ptolemy in the second century. However, its origins date back thousands of years to ancient Babylon, where it was associated with the god Enlil. In Greek tradition, Boötes is often identified as a herdsman or ploughman, with various mythic tales surrounding his role as a protector of rural life.During this time of year in the northern hemisphere, Boötes rises during twilight and becomes well-placed for observation by late evening. Conversely, from the southern hemisphere, Boötes appears low in the northern sky.

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.
