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.

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.
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.
A vibrant blue poison dart frog, *Ranitomeya aetherea*, has been identified as a new species in the western Amazon. Discovered near the Juruá River, this frog boasts striking copper highlights on its limbs and distinctive pale blue stripes. Its unique call patterns and specific habitat preferences make it a significant find, highlighting the vulnerability of such species to environmental changes.
NASA and SpaceX have rescheduled the undocking of the Dragon cargo capsule from the ISS to May 23 due to adverse weather. Part of the CRS-32 mission, the Dragon will return scientific experiments and supplies to Earth. The mission delivered 6,700 pounds of cargo to the ISS. NASA will livestream the undocking, but the splashdown will not be webcast.
Scientists have made a surprising discovery: penguin droppings in Antarctica may contribute to cooling the continent. Ammonia released from penguin guano combines with compounds from phytoplankton, boosting the formation of cloud-seeding aerosols. These aerosols then create low-lying clouds that reflect sunlight, potentially offsetting some warming effects, highlighting the intricate link between ecosystems and climate.
In a global scientific race, US and Japan are exploring the universe's existence mystery. The US-led Deep Underground Neutrino Experiment (DUNE) in South Dakota and Japan's Hyper-Kamiokande are constructing detectors to study neutrinos. These elusive particles may explain why matter exists despite the theoretical annihilation with antimatter after the Big Bang.
Group Captain Shubhanshu Shukla is preparing for the Axiom-4 mission to the ISS, now launching no sooner than June 8, 2025. This joint ISRO, NASA, and ESA mission marks a significant step for India's space program. Shukla will conduct experiments, including space agriculture research, and engage with Indian students via live broadcast.
For Narlikar, it was his way of saying that the universe couldn’t have appeared all at once. The Big Bang theory, he felt, was too sudden, too convenient—and too close to the idea of a divine creation. He also pointed out that the theory had strong support from the Church: after all, it was first proposed by a Catholic priest, Georges Lemaître, and even endorsed by the Pope.
A major solar storm is approaching Earth. NASA and other agencies issued warnings. This storm may cause radio blackouts and GPS issues. Vivid auroras are expected. The Sun's activity is increasing. Scientists are monitoring sunspot regions. The storm might affect power grids and satellites. The UK and Ireland could see Northern Lights. People should prepare for communication disruptions.
Scientists have engineered innovative contact lenses that grant humans the ability to see in the dark by converting infrared light into visible images. These nanoparticle-infused lenses offer potential applications in rescue operations, security, and medicine, eliminating the need for bulky, powered goggles.
