Every day, Earth is bombarded by cosmic rays—mysterious and powerful particles that travel across the Universe. While these high-energy entities come primarily from distant regions, recent findings circle back to our cosmic neighborhood. The detection of extremely high-energy cosmic-ray electrons and positrons—collectively known as cosmic ray electrons (CRe)—by the H.E.S.S. Observatory in Namibia has provided

In a remarkable twist of fate during its explorations, NASA’s Curiosity rover unearthed a striking surprise on the surface of Mars: pure elemental sulfur. The event occurred when the rover, weighing 899 kilograms, inadvertently cracked open an unassuming rock in the Gediz Vallis Channel, revealing brilliant yellow crystals of brimstone. This accidental encounter marks a

Albert Einstein’s theory of general relativity fundamentally altered our understanding of gravity and its role in shaping the cosmos in the early 20th century. It provided a mathematical framework that describes how massive objects warp the fabric of space-time, effectively influencing the movement of other objects. This groundbreaking theory, which has withstood the test of

In recent times, astronomers have honed their techniques to determine the metallicity of stars with precision, shedding light on an intriguing phenomenon observed among sibling stars, known as co-natal stars. Classically, these stars, born from the same molecular cloud, are expected to maintain similar metal content. Yet, studies increasingly reveal significant disparities in metallicity that

The quest for extraterrestrial life has long fascinated humanity, and Mars, often considered our neighboring lab for exploration, remains at the forefront of this inquiry. Despite extensive investigations, conclusive evidence of life on the Red Planet has yet to be unearthed. However, the Viking landers’ missions of the 1970s sparked excitement and hope—a potential glimpse
