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.
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.
New research challenges the long-held belief that asteroid Vesta is a protoplanet. Scientists at Michigan State University suggest Vesta is a fragment of a larger, extinct planet shattered in a massive collision 4.5 billion years ago. Gravity data from NASA's Dawn mission reveals no metal-rich core, contradicting earlier assumptions and redefining planetary evolution.
Researchers propose a lunar space elevator using existing materials, potentially revolutionizing space travel within decades. Anchored on the moon and extending to Earth's orbit, this "spaceline" could drastically cut mission costs and fuel needs. It would also enable a sustainable human presence in space, facilitating lunar bases and interplanetary missions.
Astronaut Nichole Ayers, aboard the International Space Station, captured a stunning display of the Northern Lights over North America. While photographing severe storms, Ayers unexpectedly witnessed the vibrant green and purple aurora, triggered by heightened geomagnetic activity. The NOAA reported a Kp index of 6, enhancing visibility from space and Earth.
President Trump unveiled the Golden Dome, a $175 billion missile defense program integrating ground- and space-based technologies. Led by General Michael Guetlein, the system aims to neutralize threats at all stages, offering unprecedented security. While initial costs range from $25 billion to $35 billion, long-term expenses could reach $831 billion, potentially nearing $1 trillion within two decades.
Space advocates, including those from Mississippi's Stennis Space Center and Louisiana's Michoud Assembly Facility, rallied in Washington, D.C., to protect NASA programs amid proposed budget cuts. They emphasized the importance of continued funding for the Artemis program, which is vital for America's space ambitions and supports thousands of jobs in the Gulf Coast region.
Mega tsunamis are colossal waves triggered by geological events. Lituya Bay saw the tallest tsunami ever recorded. Hawaii faces threat from volcanic landslides. Cumbre Vieja volcano poses Atlantic tsunami risk. Cascadia subduction zone is a ticking time bomb. Melting glaciers increase landslide risks. Early warning systems and preparedness are crucial. These events highlight nature's power and the need for vigilance.
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.
