The solar eclipse on September 21, 2025, a partial eclipse, will be visible in the Southern Hemisphere, including Australia, New Zealand, and Antarctica. India will miss direct visibility, but can view it via live streams. At its peak, nearly 85% of the Sun will be covered, offering a dramatic view for those within the path of visibility.

Scientists at the University of Copenhagen have developed BAETA, a new material made from upcycled PET plastic that efficiently captures CO2. This innovative solution transforms plastic waste into a valuable resource for combating climate change by absorbing CO2 from the air or industrial exhaust. BAETA offers a sustainable approach to addressing both plastic pollution and greenhouse gas emissions.

NASA's Artemis II mission offers a unique opportunity for global participation by sending names on its first crewed lunar flyby in over 50 years. Scheduled for launch no later than April 2026, the mission will carry four astronauts and a memory card containing millions of submitted names.

NASA has barred Chinese nationals from its space programs, citing security concerns and China's growing space ambitions. This decision restricts access to NASA facilities and data, intensifying the 'second space race' as both nations vie for lunar dominance. With valuable resources at stake, the US aims to prevent China from leading in lunar exploration, highlighting escalating tensions in space collaboration.

Research reveals that octopuses, unlike humans, don't favor a dominant arm. However, they exhibit a preference for using their front four arms for tasks like exploring, while the rear arms are more frequently employed for movement. This study, conducted in the wild, highlights the versatile capabilities and redundancy of octopus limbs in their natural environment.

SpaceX and Starlink are developing technology to enable mobile phones to connect directly to Starlink satellites within two years, potentially revolutionizing global telecommunications. This innovation aims to provide high-bandwidth connectivity worldwide, bypassing traditional carriers. The move involves updating phone chipsets and leverages SpaceX's $17 billion spectrum acquisition to enhance direct-to-cell capabilities, disrupting regional telecom providers.

John Burford, an 85-year-old former NASA scientist, has been imprisoned for two years for defrauding over 100 investors of $1.2 million. He misused his credibility to attract investors to his unregulated scheme, Financial Trading Strategies. Burford diverted funds for personal use, including purchasing a house, leading to his conviction for fraud and Financial Services and Markets Act offences.

Telescopefish, residing in tropical and subtropical waters at depths of 500 to 2,000 metres, possess remarkable adaptations for survival. Their tubular eyes act like binoculars, aiding in spotting prey, while expandable jaws enable them to consume fish larger than themselves. A cast-iron stomach conceals glowing prey, showcasing their unique predatory strategies in the deep sea.

Beneath eastern Africa, scientists have discovered a dramatic geological process driven by rhythmic pulses of molten rock rising from the Earth's mantle. This "geological heartbeat" weakens the crust, causing earthquakes and volcanic activity. Over millions of years, this process is expected to split Africa into two parts, creating a new ocean basin and reshaping the continent.

NASA's Perseverance rover has potentially discovered the strongest evidence yet of ancient life on Mars. The Cheyava Falls rock sample, collected from Jezero Crater, exhibits unusual leopard spot markings and contains organic compounds. Scientists believe these features could represent biosignatures resulting from microbial activity billions of years ago, though further research is needed to confirm this groundbreaking possibility.

A partial solar eclipse will occur on September 21, 2025. It will be visible in the Southern Hemisphere. Key locations include New Zealand and eastern Australia. The Moon will partially block the Sun. Observers in India cannot view this eclipse. Safe viewing practices are essential. The event offers scientific study opportunities. It highlights orbital mechanics and shadow geometry.

New research from NASA's InSight lander, which recorded over 1,300 Marsquakes between 2018 and 2022, suggests Mars possesses a solid inner core, approximately 600 kilometers in radius, surrounded by a liquid outer core. This discovery challenges previous assumptions of a fully liquid core and could reshape our understanding of Mars' past magnetic field and planetary evolution.
