A new study highlights the critical role of the Irminger Sea, located off southeastern Greenland, in maintaining the strength of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC, a global ocean conveyor belt, is crucial for regulating Earth’s climate, particularly in the Northern Hemisphere. According to research led by Dr Qiyun Ma, a postdoctoral researcher

NASA‘s Perseverance rover, currently exploring Mars’ Jezero Crater, has detected carbon-based molecules that may hint at ancient life on the Red Planet. These findings, reported last summer, were made using SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals), an advanced instrument capable of identifying potential organic compounds. While the discovery has

A 2,600-year-old inscription engraved on a monument in Turkey, known as Arslan Kaya or “lion rock,” has been deciphered, according to research by Professor Mark Munn of Pennsylvania State University. This ancient carving, which has endured significant damage from weathering and looting, contains references to Materan, a goddess revered by the Phrygians, an ancient civilisation

A new artificial intelligence (AI) tool, Earth Copilot, has been introduced by NASA in collaboration with Microsoft to make Earth-related scientific data more accessible. Designed to summarise NASA’s extensive geospatial information, the AI-powered chatbot aims to simplify complex datasets and answer user queries with ease. By addressing questions like the environmental impact of events or

A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This survey, conducted with the Dark Energy Spectroscopic Instrument (DESI) at the Mayall Telescope in Arizona, identified over 2,500 black holes in dwarf galaxies—more than triple

A study by the European Synchrotron Radiation Facility (ESRF) suggests that early Homo species may have experienced extended childhoods well before significant brain enlargement, challenging longstanding evolutionary assumptions. The findings are based on the dental development of a nearly complete sub-adult Homo skull, unearthed at the Dmanisi site in Georgia and dated to 1.77 million

New research on unique sandstone formations in the Colorado Rocky Mountains may confirm that Earth experienced a massive, planet-wide freeze known as “Snowball Earth.” About 700 million years ago, Earth’s surface was encased in ice, creating an extreme climate where early life not only survived but later evolved into complex multicellular organisms. For decades, the

A faint electric field has been detected in Earth’s atmosphere, confirming a theory that scientists have held for decades. This ambipolar electric field, though weak at just 0.55 volts, could play a vital role in shaping Earth’s atmospheric evolution and its ability to support life, according to recent findings. Glyn Collinson, an atmospheric scientist at

Evidence of an ancient ocean on Mars has been potentially uncovered by China’s Zhurong rover, scientists report. Data gathered by the now-defunct rover indicates a possible ancient shoreline in Mars’ northern hemisphere. Researchers at Hong Kong Polytechnic University, including lead scientist Bo Wu, believe these findings support long-standing theories of a large Martian ocean that

A recent study of black hole jets from NASA’s Chandra X-ray Observatory has identified bright formations or “knots” in these jets, with each showing unexpected variations in speed. This analysis, led by David Bogensberger, an astrophysicist at the University of Michigan, examined decades-old Chandra data on the supermassive black hole at the heart of the
