The deep ocean, covering most of Earth, remains largely unexplored, with only 0.001% visually studied. It regulates climate, harbors unique ecosystems, and holds potential resources. However, human activities like climate change, pollution, and overfishing threaten this vital environment before its true value is understood, necessitating urgent conservation efforts and sustainable practices.

Scientists are using satellite data to monitor tree health near volcanoes. Trees absorb volcanic carbon dioxide, which makes them greener. NASA's AVUELO project and other satellites track these changes. This helps detect early signs of volcanic activity. The goal is to improve volcano early warning systems, especially in remote areas. Ground observations are crucial for verifying satellite data.
SpaceX's Starship rocket exploded during a test. The issue was a fuel reaction in an engine. The company made fixes, including better insulation. The Federal Aviation Administration approved the changes. A new test flight is set for May 27. This flight will reuse a Super Heavy booster. SpaceX aims to use Starship for Moon and Mars missions.
ISRO Chairman Dr. N. Narayanan declared 2025 as 'Gaganyaan Year,' highlighting India's ambitious human spaceflight program. The uncrewed Gaganyaan mission, featuring the Vyommitra robot, is set for December 2025, paving the way for a manned mission in early 2027. ISRO is also advancing lunar exploration with Chandrayaan-4, aiming to return lunar samples, and Chandrayaan-5, a collaborative mission with Japan.
A recent Virginia Tech study reveals that the Pacific Northwest faces a heightened risk of catastrophic flooding and mega-tsunamis, potentially reaching 1,000 feet. The Cascadia Subduction Zone's inactivity since 1700, coupled with climate change, intensifies the threat. Coastal land subsidence and rising sea levels could overwhelm communities, impacting thousands and vital infrastructure.

His work with Dr. Homi Bhabha on the Apsara reactor and his leadership in building Pressurized Heavy Water Reactors were crucial.
Recent intense solar flares, originating from sunspot AR4087, have triggered global concerns about potential space weather impacts. A FEMA-led drill simulating a solar superstorm exposed critical preparedness gaps across agencies. Recommendations from SWORM emphasize enhanced monitoring, interagency cooperation, and public education to bolster resilience against future solar events, safeguarding essential infrastructure and national security.
Asteroid 2003 MH4, a large space rock about three football fields in length, will make a close approach to Earth around May 24, 2025. While not an immediate threat, its size and speed have prompted NASA to closely monitor its trajectory. This event highlights the importance of ongoing planetary defense efforts and the need for vigilance in tracking near-Earth objects.
A large asteroid, 2003 MH4, will pass by Earth on May 24. It is about the size of the Eiffel Tower. The asteroid will travel at 30,060 kilometers per hour. NASA considers this a close encounter. Continuous monitoring of near-Earth objects is important. Even small gravitational changes can alter an asteroid's path.
Scientists have identified *Ikaria wariootia*, a tiny wormlike creature from 555 million years ago, as the earliest known bilaterian. This discovery from South Australia reveals the origin of bilateral body structure, a key feature in most animals today. The fossil's characteristics and burrowing behavior provide insights into early animal evolution and locomotion.
