asteroid detection

South Africa's Vredefort crater, the Earth's largest proven meteorite impact site, defies the typical circular depression image. Formed 2 billion years ago, its immense initial size has been eroded, revealing a damaged core. This weathering, however, has made it a crucial geological site, offering a unique profile to study the crust's response to giant impacts.

The Green Bank Telescope recently captured a groundbreaking image of NASA's Artemis 2 spacecraft orbiting the Moon, marking a significant advancement in deep-space human exploration. This achievement demonstrates the power of radio astronomy to precisely track spacecraft, providing crucial situational awareness for future lunar missions and highlighting a new era of cosmic transparency.

Scientists have confirmed a massive impact crater, Nadir Crater, hidden beneath the Atlantic Ocean off West Africa using advanced 3D seismic technology. Estimated to be 9.2 km wide and formed around 66 million years ago, it offers crucial insights into Earth's ancient history. This discovery highlights the potential for uncovering more hidden geological events with modern imaging.

Beneath the serene Chesapeake Bay lies a hidden secret: a massive impact crater, nearly 53 miles wide, formed by a mountain-sized object over 35 million years ago. This ancient wound, buried under thousands of feet of sediment, continues to influence water flow and land subsidence in the region, revealing the enduring power of a cataclysmic event.

US authorities are investigating a concerning pattern of American scientists, with access to sensitive research, going missing or dying since mid-2024. The White House, FBI, and Congress are collaborating to uncover potential links, including foreign actor involvement. Multiple agencies are reviewing at least eleven cases, some dating back to 2022, to assess national security implications.

Analysis of samples from the asteroid Ryugu has revealed all five nucleobases essential to DNA and RNA, strengthening evidence that life’s chemical building blocks are widespread in space. While not proof of extraterrestrial life, the finding suggests asteroids could have delivered key ingredients to early Earth, offering new insight into how life’s fundamental chemistry may emerge across the universe.

A series of disappearances and deaths involving individuals linked to sensitive US nuclear and aerospace programs between July 2024 and February 2026 has sparked speculation. While some cases remain baffling mysteries, others have clear explanations, suggesting a complex mix of events rather than a single conspiracy. The article explores these incidents, highlighting the real overlaps and the rampant speculation.

The James Webb Space Telescope has found many small asteroids. Some are heading towards Earth. These asteroids are smaller than the dinosaur-killing ones. But they are still dangerous. A small asteroid exploded over Russia a decade ago. Scientists have new methods to track these asteroids. This helps protect Earth from impacts.

Earth faces a significant threat from thousands of undetected asteroids capable of destroying cities. NASA's planetary defence chief warns that current systems cannot reliably stop these 'city-killers'. While progress is being made with new telescopes and international efforts, a substantial gap remains in our ability to detect and deflect such objects before they impact our planet.

A 70 cm asteroid is expected to enter Earth's atmosphere over northern Siberia tonight around 9:45 pm IST. Experts predict it will burn up, creating a stunning fireball, posing no danger to Earth. This event highlights the advancements in asteroid tracking technology by NASA and ESA and the importance of monitoring near-Earth objects for planetary defense.

A small asteroid named C0WEPC5, about 70 cm in diameter, will collide with Earth over Northern Siberia, creating a harmless fireball. The impact is predicted at 9:45 PM IST. This marks the fourth predicted asteroid impact this year. The asteroid was discovered by Kitt Peak National Observatory and poses no significant threat.

A new threat looms as scientists warn of dangerous asteroids near Venus, hidden from Earth's telescopes by the Sun's glare. These Venus co-orbitals, including asteroids like 2020 SB, pose a collision risk due to their unstable orbits. Experts urge for dedicated space missions to monitor this blind spot and enhance planetary defence, safeguarding Earth from potential catastrophic impacts.

Extensive monitoring systems and an Armageddon-style protocol is needed to save the Earth from a potentially hazardous asteroid, expected to fly by our planet in 2029, experts say.

A small asteroid, C0WEPC5, entered Earth's atmosphere and burned up over Siberia on December 4, 2024, producing a bright fireball. Detected just hours prior, it highlighted advancements in monitoring techniques. This marks the fourth imminent impactor detected this year, demonstrating improved observational capabilities.

The discovery of an asteroid the size of a small shipping truck mere days before it passed Earth on Thursday, albeit one that posed no threat to humans, highlights a blind spot in our ability to predict those that could actually cause damage, astronomers say.

A newly discovered asteroid, 2025 SC79, is drawing global attention due to its unusual orbit inside Venus's path and its rapid 128-day solar circuit. This 'twilight' asteroid, roughly 700 meters across, is difficult to detect due to the Sun's glare, highlighting the challenges of monitoring near-Sun objects and their potential impact risks.
