Ancient Asteroid Impact Supercharged Earth's Evolution 3.2 Billion Years Ago

A recent study published in the Proceedings of the National Academy of Sciences reveals the catastrophic impact of the S2 asteroid, which struck Earth 3.2 billion years ago. With a diameter between 40 and 60 kilometers, the asteroid caused massive shockwaves, ocean boiling, and mega tsunamis, creating apocalyptic conditions. Despite these challenges, life on Earth, particularly non-photosynthetic microorganisms, thrived due to the release of nutrients like phosphorus and iron. This event highlights the resilience of life and offers insights into the potential for life in extreme conditions on other planets.

"NASA Confirms 'Lost' Asteroid Poses No Threat to Earth in 2024"

NASA has confirmed that the "lost" asteroid 2007 FT3, which was initially thought to have a slim chance of impacting Earth in 2024, poses no threat. Despite earlier concerns based on a British news report, NASA's tracking and analysis indicate there are no known asteroid threats to Earth for the next century. The agency continues to monitor near-Earth objects (NEOs) as part of its planetary defense strategy. While 2007 FT3 is not a concern, NASA has noted a 1 in 2,700 chance of asteroid Bennu impacting Earth in 2182. NASA's recent mission to collect samples from Bennu aims to further our understanding of the origins of life, and its successful test of an asteroid-deflecting spacecraft in 2022 demonstrates ongoing preparedness for potential future threats.

"NASA Debunks Viral Doomsday Claims, Confirms No Asteroid Threat in 2024"

The asteroid 2007 FT3, lost after a brief observation period in 2007, has a small chance of impacting Earth on October 3, 2024, with NASA estimating the odds at about one in 11.5 million. Despite being fourth on NASA's list of potential impactors, there is no significant concern among astronomers, as even the most likely candidates are not expected to hit Earth in the next century. The potential impact would not be catastrophic to human existence but would still result in a very bad day.

"NASA Debunks Fears, Confirms 'Lost' Asteroid 2007 FT3 Harmless to Earth"

NASA has reassured the public that the 'lost' asteroid 2007 FT3, which briefly caused concern over a potential impact on October 5, 2024, poses no threat to Earth. Despite the asteroid's size and the initial 89 potential impact scenarios, updated calculations and continuous monitoring have confirmed that there are no known asteroid threats to Earth for the next century. NASA's ongoing efforts in tracking near-Earth objects (NEOs) and improving planetary defense capabilities, including the successful test of a defense strategy last year, contribute to the agency's confidence in mitigating any potential asteroid collision risks.

"NASA Addresses Concerns Over Potential 2024 Impact of 'Lost' Asteroid with Catastrophic Force"

A simulation video by MetaBallStudios, which has gone viral, illustrates the catastrophic effects of various sized asteroids hitting Earth, with the smallest creating a 1.16km crater in New York City. The largest asteroid in the simulation causes a colossal 840km crater, affecting the whole of Europe. The video has sparked discussions online, with many expressing concern over the potential real-life impact of Asteroid 2007 FT3, which could release the energy equivalent to 2.6 billion tons of TNT, though it's not large enough to cause an extinction-level event.

"NASA Addresses Fate of 'Lost' Asteroid Potentially Striking Earth in 2024"

NASA has addressed concerns about the "lost" asteroid 2007 FT3 potentially impacting Earth on October 5, 2024. The asteroid, which was observed briefly in 2007, is on NASA's Sentry Risk Table but has not been seen since its initial sighting. Despite 89 potential impacts identified, including the one in 2024, NASA has stated there are no known asteroid threats to Earth in the next century. The agency continues to monitor near-Earth objects (NEOs) and has a good track record of predicting their orbits. If 2007 FT3 is observed again, more accurate predictions can be made, and if necessary, a deflection mission could be prepared.

NASA Confirms Potential 2024 Impact of Rediscovered Asteroid

NASA has re-identified Asteroid 2007 FT3, which was lost after its discovery in 2007, and predicts it could potentially hit Earth next year with a chance of one in 11 million. The impact, expected on October 5, 2024, could release energy equivalent to 2.6 billion tons of TNT, but is not considered an extinction-level threat. The asteroid is one of many Near Earth Asteroids (NEAs) tracked by NASA, with larger asteroids like 29075 (1950 DA) posing a more significant risk. Jupiter is theorized to act as a shield for Earth by attracting some impacts that could otherwise threaten our planet.
