Nearly 49 years after its launch, NASA's Voyager 1 continues to send data from around 25 billion kilometres away, making it the most distant human-made object in space. As its power supply slowly declines, NASA is carefully switching off onboard systems to keep the spacecraft operational. Voyager 1 is also expected to reach another milestone in 2026, when a signal from Earth will take a full 24 hours to reach it.

Despite the vastness of Earth's oceans, only about thirty percent of the seafloor is charted to modern specifications, revealing a stark difference with Mars, whose surface boasts complete mapping. The Seabed 2030 initiative has dramatically improved ocean coverage from six to nearly twenty-nine percent. This meticulous mapping relies on ships and sonar, a time-intensive endeavor crucial for effective tsunami predictions and maintaining submarine cables.

In a radical move, Ignaz Semmelweis mandated handwashing in hospitals, drastically reducing maternal mortality rates. Despite evidence supporting his approach, he faced fierce opposition from fellow medical professionals, as he couldn't provide a scientific rationale for his findings. Much later, the establishment of germ theory validated his revolutionary work, leading to fundamental changes in medical practices that ultimately saved innumerable lives.

California's coast is witnessing a heartbreaking seabird crisis, with thousands of emaciated birds washing ashore. This alarming trend, driven by a prolonged marine heatwave and El Nio, is disrupting the ocean's food web. Scientists warn this could be a clear sign of climate change's severe impact on marine ecosystems, with potential long-term consequences for biodiversity and coastal economies.

In an extraordinary breakthrough, researchers have isolated ancient human DNA from prehistoric cave paintings found in Spain and Portugal. Published in Nature Communications, this pioneering work opens doors to identifying the creators of these works, including their gender and lineage. The DNA seems to have seeped through bodily fluids, giving us a fascinating link to the artists who crafted these enduring relics thousands of years ago.

Recent research has unveiled that giant ocean whirlpools, also termed mesoscale eddies, play a crucial role in transporting freshwater from the Congo River into the Atlantic Ocean. These dynamic currents, characterized by their power and fleeting existence, can capture substantial volumes of river water and transport it hundreds of kilometers away.

Microscopic nanobubbles are being tested at Washington D.C.'s Lincoln Memorial Reflecting Pool to combat algal blooms. This innovative technology, injecting ozone nanobubbles, effectively cleans water and holds promise for restoring oxygen-starved lakes and seas suffering from eutrophication. Scientists are exploring methods to deliver these oxygen-carrying bubbles directly to the sediment layer, where critical environmental issues begin, offering a potential solution for vast polluted water bod

A colossal 11-foot king cobra, seeking a nap, became dangerously ensnared in a truck's bumper in Thailand. Rescuers endured a tense four-hour ordeal, skillfully extracting the agitated reptile. This incident mirrors a similar rescue in India last year, highlighting the increasing overlap between wildlife and human spaces and the vital role of trained responders in ensuring safety for both.

India's space agency, ISRO, has successfully tested the solid motor for its new SOLVE launch vehicle, a crucial step for the Gaganyaan human spaceflight program. This test platform will aid in validating the crew module's parachute system for safe return. SOLVE, adapted from PSLV technology, will offer flexibility in simulating mission conditions, paving the way for upcoming uncrewed Gaganyaan flights.

Astronomers have spotted a remarkably small yet potent galaxy, MXDFz4. 4, from the universe's nascent stages. This galaxy, observed by Hubble and confirmed by other powerful telescopes, is emitting energetic ultraviolet light, a phenomenon previously thought impossible for its era. This discovery offers an unprecedented glimpse into how early galaxies began to clear the cosmic fog, paving the way for light to travel freely.

Scientists have uncovered evidence of a massive magma system beneath Mars' surface, challenging the long-held belief that such complex geological activity requires tectonic plates. NASA's InSight lander data revealed a distinct boundary deep within the Martian crust, suggesting a vast, ancient magma chamber that cooled and crystallized. This discovery hints that the ingredients for life might be more common on Mars than previously thought, prompting a re-evaluation of planetary habitability.

Vincent van Gogh's iconic The Starry Night has revealed a scientific secret. Physicists analyzing the painting's swirling patterns discovered they closely resemble the statistical models of turbulence, a complex natural phenomenon. This suggests Van Gogh, through his keen observation, captured the visual essence of fluid motion over a century before scientists could mathematically describe it, making his masterpiece a surprising echo of nature's mysteries
