British composer George Fenton has died at the age of 76. He was known for scores to films including The Fisher King, Groundhog Day and Dangerous Liaisons, and for landmark natural history series such as Planet Earth and Blue Planet. Fenton was one of Britain's most respected film and television composers, with a career spanning decades and numerous award nominations.

Japanese media are reporting on Nagae Tsuruno Geito (alligator weed), described as one of the worst invasive plants on Earth. It has been confirmed in Oita, and new research from Fukui and Ibaraki shows the plant has exceptionally high photosynthetic capacity that drives rapid stem growth. Scientists say identifying this weakness could lead to more effective control methods as the weed spreads along rivers.

Tenzin Seldon is calling for a shift in how economic success is measured, arguing that national and corporate metrics should account for what the economy restores — such as ecosystems and communities — rather than focusing solely on production and growth. The argument is being aired in an interview published by One Earth, adding to ongoing debate about moving beyond GDP as the main yardstick of prosperity.

Scientists are still puzzling over an ultra-high-energy particle that struck Earth's atmosphere in 2023, and one new proposal offers an exotic answer: cosmic strings, hypothetical wrinkles in spacetime left over from the early universe. Making the idea work would require a lot of cosmic strings, but researchers argue wild events may demand wild explanations, and the debate is drawing attention across physics circles.

Researchers say Saturn's moon Enceladus, long considered one of the most promising places to look for alien life, could plausibly support extraterrestrial organisms. The icy moon is known to have a subsurface ocean beneath its frozen shell, and the new findings strengthen the case that its environment may be habitable, keeping it high on the list of targets in the search for life beyond Earth.

The four astronauts of SpaceX's Crew-12 mission have undocked from the International Space Station to begin their journey back to Earth after spending nearly ten months in orbit. Their extended stay made the mission one of the longer crewed rotations to the station, and their return via a SpaceX Crew Dragon capsule is drawing broad attention.

NASA is highlighting research into persistent drought across the Texas cotton belt, where farmers face shrinking yields and depleted soil moisture. The agency's earth science work uses satellite data to track drought conditions and water use in one of the world's most important cotton-growing regions. The reporting comes as prolonged dry conditions continue to strain agriculture across the southern Plains, drawing attention to how growers and scientists are responding.

NASA's Voyager 1, now 25.78 billion kilometers (16.02 billion miles) from Earth, is on track to become the first human-made object to sit a full light-day away — meaning a radio signal would take 24 hours each way — in about 42 days and 18 hours. Voyager 2 trails at 21.57 billion kilometers. Space watchers are marking the milestone as a striking measure of how far the 1977 probes have traveled.

NASA's Voyager 1, now about 25.78 billion km (16.02 billion miles) from Earth, is on track to reach a distance of one light-day — the distance light travels in a day — in roughly 41 days and 18 hours. Its twin Voyager 2 sits closer, at about 21.57 billion km (13.41 billion miles). Space enthusiasts are marking the milestone, noting the spacecraft launched in 1977 remains the farthest human-made object from Earth.

Scientists have floated a new, unconventional explanation for an ultra-high-energy cosmic ray detected in 2023, one of the most powerful particles ever recorded striking Earth's atmosphere. The particle, nicknamed the Amaterasu particle, appeared to come from empty space with no obvious source, puzzling physicists. The latest proposal is described as among the strangest explanations offered so far for where it could have originated.

NASA's Voyager 1, launched in 1977 and now the most distant human-made object, is about 25.78 billion km (16.02 billion miles) from Earth. At its current distance, a radio signal takes nearly a full day each way, and the probe is set to cross the one-light-day mark in roughly 42 days. Voyager 2 trails at about 21.57 billion km. Space watchers are marking the milestone as a symbolic moment in interstellar exploration.

NASA's Voyager 1, now 25.79 billion kilometres from Earth, is on track to reach a distance of one light-day — the distance light travels in a day — in roughly 40 days. Voyager 2, its twin, sits at 21.58 billion kilometres. The milestone is being noted as a striking measure of how far the 1977-launched probes have travelled into interstellar space.

NASA's Voyager 1, humanity's farthest spacecraft, is currently about 25.77 billion kilometers (16.01 billion miles) from Earth and is on track to reach a distance of one light-day within roughly 45 days. Its twin Voyager 2 trails at about 21.56 billion kilometers (13.4 billion miles). Space enthusiasts are tracking the milestone, which would mark the first time a human-made object is a full light-day away from our planet.

Milt Windler, one of NASA's flight directors during the Apollo era, has died at the age of 94. Windler was part of the team of flight directors credited with helping bring the crew of Apollo 13 safely back to Earth in 1970 after an explosion crippled the spacecraft on its way to the Moon. Tributes are circulating among space enthusiasts recalling his role in one of NASA's finest hours.

Antarctica remains one of the most important regions on Earth for predicting future sea-level rise. It contains enough ice to raise global mean sea levels by an estimated 3 to 4 meters (10–13 feet). A recent review concludes that major gaps in observations mean scientists still cannot accurately forecast how quickly that ice will be lost, underscoring the urgency of expanded polar research and monitoring.

NASA's Voyager 1 probe is now 25.78 billion kilometres (16.02 billion miles) from Earth and is set to reach a distance of one light-day — the distance light travels in a full day — in roughly 43 days and 18 hours. Its twin, Voyager 2, trails behind at 21.57 billion kilometres. Space watchers are marking the milestone as the farthest human-made object edges further into interstellar space.

Scientists say an elongated cloud stretching some 1,100 miles over Mars operates on atmospheric physics that has never been observed before. The cloud, which repeatedly forms near a giant volcano on the Red Planet, cannot be fully explained by existing models, prompting researchers to reconsider how Martian weather works. The finding is drawing attention for what it may reveal about atmospheres beyond Earth.

Voyager 1, NASA's most distant spacecraft, is now 25.78 billion kilometres (16.02 billion miles) from Earth and is on course to reach a distance of one light-day within roughly 44 days. Its twin, Voyager 2, sits closer at 21.57 billion kilometres. Reaching one light-day would be a symbolic milestone for the nearly 50-year-old mission, meaning even light takes a full day to travel between the probe and Earth.
