Notes:
Preliminary data from NASA’s James Webb Space Telescope (JWST) suggests a more than 50% likelihood of dimethyl sulfide (DMS) gas on the exoplanet K2-18b. However, further analysis is required before a definitive conclusion can be reached. DMS is a gas that is only produced by living beings on Earth, primarily by phytoplankton in marine environments. The presence of DMS in K2-18b’s atmosphere could be a groundbreaking discovery, as the planet is believed to be ocean-covered and 2.6 times larger than Earth. K2-18b, discovered in 2015, is a super Earth exoplanet orbiting an M-type star. M stars, smaller and cooler than the sun, comprise the Red Dwarf category. K2-18b resides in the Goldilocks zone, where temperatures sustain liquid water.

Notes:
Scientists continue to explore Mexico’s Taam Ja’ Blue Hole in Chetumal Bay, hinting at a connection to a complex network of underwater caves. Blue holes, like Taam Ja’, are sinkholes formed by the dissolution of soluble rock, such as limestone. Taam Ja’ is the world’s deepest known underwater sinkhole, plunging at least 1,380 feet below sea level. It surpasses the previous record holder, the Sansha Yongle Blue Hole, by 390 feet.

The Supreme Court ordered an end to illegal mining in the Aravalli Range in Rajasthan. Stretching 692 kilometers across Gujarat, Rajasthan, and Haryana, the Aravallis are India’s oldest mountain range, vital for ecology and hydrology. They prevent desertification, regulate climate, and support diverse ecosystems and rivers like Sabarmati and Luni. Abundant in biodiversity, the range hosts dry deciduous forests, scrublands, and numerous species of mammals, birds, reptiles, and insects.

Notes:
The Aeronautical Development Establishment, a Bengaluru-based Defence Research and Development Organisation (DRDO) lab, creator of Lakshya aircraft, is under CBI scrutiny. Lakshya, a micro-light, pilot-less aircraft, was developed by ADE for Indian Armed Forces, inducted in 2000 (IAF), 2001 (IN), and 2003 (IA). Cost-effective, reusable, with HAL-manufactured engine, it aids weapon system trials, carries tow targets for training, and launches from land or sea.
