New Satellite Data Confirms Greenland's Mega-Tsunami That Shook Earth For 9 Days
A powerful tsunami caused by a massive rockslide in Greenland in 2023 shook the Earth for nine and new satellite data has now confirmed the full extent of its impact. The rare event, which took place in a remote sea valley, sent waves bouncing back and forth within steep cliffs, creating seismic tremors detected thousands of miles away.
The international Surface Water and Ocean Topography (SWOT) satellite, operated by NASA and France's CNES, detected the movement of water in Dickson Fjord, located on Greenland's eastern coast.

How will Earth take its last breath? New research gives a detailed description of how life on planet will meet its end
A new study, employing NASA's planetary modeling, predicts Earth's oxygen will vanish in roughly one billion years, much sooner than previously thought. Led by Toho University, the research highlights the sun's aging process as a key factor, causing increased water evaporation, rising temperatures, and a failing carbon cycle. Tired of too many ads? Remove Ads What has the research revealed? Tired of too many ads? Remove Ads Researchers shorten Earth's lifeline A groundbreaking study by researchers at Toho University, using NASA's advanced planetary modeling, has predicted a major shift in Earth's atmosphere that could make life as we know it in Nature Geoscience, the research suggests that Earth's oxygen could vanish in about one billion years—shedding new light on the long-term evolution of our planet's team ran 400,000 simulations to model how Earth's atmosphere might change as the sun grows hotter with age. While the predicted changes lie far in the future, the findings offer critical insights into planetary science and the eventual fate of Earth's study titled "The Future Lifespan of Earth's Oxygenated Atmosphere" explores a future in which oxygen becomes increasingly scarce due to natural changes in the planet's systems. Led by Kazumi Ozaki, an assistant professor at Toho University in Tokyo, the research examines the geological and astronomical factors influencing long-term shifts in Earth's role of the Sun One of the core factors leading to oxygen depletion is the sun's inevitable aging process. As the sun ages, it will gradually become hotter and brighter. This increase in solar radiation will significantly impact Earth's climate, leading to a series of irreversible changes:As temperatures rise, Earth's water bodies will evaporate more rapidly, increasing atmospheric water vapor levels. This warming will also cause surface temperatures to escalate, gradually creating conditions unsuitable for sustaining life. The heat will disrupt the carbon cycle—a crucial process that regulates atmospheric carbon dioxide—weakening its ability to maintain balance. As a result, plant life will begin to die off, stopping the production of oxygen through photosynthesis. Over time, these cascading effects will lead to a dramatic loss of oxygen in Earth's atmosphere, rendering the planet increasingly research revealed that as the carbon cycle deteriorates, the atmosphere will revert to a composition reminiscent of early Earth, characterized by high levels of methane and low oxygen. This transformation mirrors the state before the Great Oxidation Event—a period when Earth's atmosphere became rich in oxygen due to the proliferation of photosynthetic scientific models suggested that Earth's biosphere would last up to two billion years, primarily due to overheating and the eventual depletion of CO₂ necessary for photosynthesis. However, this new research narrows the timeframe, suggesting a much earlier end to oxygen Ozaki emphasized that while the eventual demise of Earth's biosphere was acknowledged, pinpointing the timing and the precise process of deoxygenation remained elusive. This study, using advanced supercomputer simulations, provides a clearer understanding by simulating numerous potential scenarios.

Indian astronaut Shubhanshu Shukla's launch, arrival details at ISS out by NASA; Check how to stream, date, time, other key details here
NASA , Axiom Space, and SpaceX are targeting 8:22 a.m. EDT, Tuesday, June 10, for launch of the fourth private astronaut mission to the International Space Station , Axiom Mission 4 , according to a recent press statement of US space agency. For India, 8:22 a.m. EDT translates to 5:52 pm IST. The mission will lift off from Launch Complex 39A at NASA's Kennedy Space Center in Florida. The crew will travel to the orbiting laboratory on a new SpaceX Dragon spacecraft after launching on the company's Falcon 9 rocket. The targeted docking time is approximately 12:30 p.m., Wednesday, June 11. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 2024-2025 Models: Small SUVs Are Turning Heads (Take A Look) FrequentSearches | Search Ads Learn More Undo How to stream the launch and arrival activities? NASA will stream live coverage of launch and arrival activities on NASA+. What is the role of Shukla? Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, will command the commercial mission, while ISRO ( Indian Space Research Organisation ) astronaut Shubhanshu Shukla will serve as pilot. The two mission specialists are ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland and Tibor Kapu of Hungary. Live Events As part of a collaboration between NASA and ISRO, Axiom Mission 4 delivers on a commitment highlighted by President Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies are participating in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration. The private mission also carries the first astronauts from Poland and Hungary to stay aboard the space station. NASA's mission coverage is as follows (all times Eastern and subject to change based on real-time operations): Check full schedule Tuesday, June 10 6:15 a.m. – Axiom Space and SpaceX launch coverage begins. 7:25 a.m. – NASA joins the launch coverage on NASA+. 8:22 a.m. – Launch NASA will end coverage following orbital insertion, which is approximately 15 minutes after launch. As it is a commercial launch, NASA will not provide a clean launch feed on its channels. Wednesday, June 11 10:30 a.m. – Arrival coverage begins on NASA+, Axiom Space, and SpaceX channels. 12:30 p.m. – Targeted docking to the space-facing port of the station's Harmony module. Arrival coverage will continue through hatch opening and welcome remarks. Astronaut Shubhanshu Shukla blasts off into space next week as the first Indian to join the International Space Station (ISS), bearing with him New Delhi's dreams of its own manned space flight. An airforce fighter pilot, 39-year-old Shukla is joining a four-crew mission launching from the United States with private company Axiom Space, aboard a SpaceX Crew Dragon capsule. He will become the first Indian to join the ISS, and only the second ever in orbit -- an achievement that the world's most populous nation hopes will be a stepping stone for its own human flight.
