  From a young age, Manasvi Lingam , an assistant professor of astrobiology at Florida Tech , has been captivated by the mysteries of life's origins . As a child, he would bombard his family with questions about dinosaurs and aliens , seeking to understand how life could exist on other planets.

His latest study uses Bayesian analysis to explore the possibility of life originating on Earth from non-life, also known as abiogenesis . Collaborating with researchers from Florida Tech and the University of Rome, Lingam developed models to analyze how many sites on Earth could have been suitable for life to start and how likely life was to emerge at those sites. Surprisingly, Lingam found that having fewer suitable sites for life increased the likelihood of life's emergence. This counterintuitive finding challenges the notion that "more is better" and opens up ...

  In a breakthrough discovery, India's lunar rover " Pragyan " has unveiled evidence of the Moon's ancient global magma ocean . The findings, published in Nature by an Indian research team, mark the first-ever measurements from the Moon's polar highlands , broadening our understanding of the Moon's early history. The Pragyan rover’s wheels penetrated several centimeters into the lunar soil, allowing the rover’s APXS instrument to analyze the composition of the lunar regolith below the top surface layer. Credit: ISRO Around 4.5 billion years ago, a cataclysmic collision in the early solar system led to the formation of the Moon, which was once covered by a vast ocean of molten magma. This theory gained more robust backing after Pragyan's investigation of the rocks at the Vikram lander's site, now named "Point Shiv Shakti," located near the Moon's south pole. The rover analyzed samples using an Alpha Particle X-ray spectrometer (APXS),...
