Researchers at the University of Texas at Austin have redated a meteor impact site in Oklahoma, shifting its age from 467.5 million years ago to 370 million years ago. This discovery has significant implications for understanding ancient life and mass extinctions.
A new study reveals that Mercury's surface is 10-30% smaller than previously thought, with impact debris covering the signs of contraction. Researchers used combined maps of geologic evidence and surface roughness to estimate the planet's contraction, finding a total change of up to 14.5 miles in its diameter.
A new study reveals that the Moon's soil can be decoded to reveal history of supernova explosions. Researchers developed a mathematical model to unscramble the lunar surface, providing guidance for future core samples. The model reveals insights into the history of our Solar System's journey through the galaxy.
A Southwest Research Institute-led study proposes a connection between an asteroid collision and an inner-solar-system-wide bombardment episode 800 million years ago. The research suggests that the catastrophic breakup of the Eulalia parent body may have led to widespread impacts on Earth, coinciding with biological and geological chan...
A new study found that AI-generated lunar crater catalogs often perform poorly when evaluated using human-defined scientific standards. The research highlights the need for standardizing benchmarks and transparent reporting to ensure the accuracy of AI-generated data.
A Johns Hopkins University study finds that tiny life forms can survive extreme pressure comparable to an ejection from Mars after an asteroid hit, and may potentially move between planets. The discovery raises implications for planetary protection and space missions.
A team of researchers from Shanghai and Guangzhou, China, has discovered the Jinlin crater, a 900-meter diameter impact structure preserved within a thick granite weathering crust. The discovery provides new insights into the scale of small extraterrestrial object impacts on Earth during the Holocene epoch.
A new study of the South Pole-Aitken basin reveals clues about the moon's interior structure, crust composition, and evolutionary history. The research suggests that the moon's near side was heated by radioactive elements from a magma ocean, leading to intense volcanism.
Politecnico di Milano will contribute to the RAMSES mission, studying Apophis' physical and dynamic properties through imagery and data gathered during its flyby. The university's team developed autonomous navigation algorithms that will serve as a test platform for new technologies.
A study found that a hydrothermal system created by an asteroid impact helped marine life flourish in the Gulf of Mexico for at least 700,000 years. The system generated and circulated nutrients, supporting high-nutrient environments that favored certain types of plankton.
Scientists precisely dated the formation of the Moon's largest impact crater, the South Pole-Aitken Basin, to 4.25 billion years ago using Chang'e-6 samples. The discovery provides critical insights into the early history of the Moon and the Solar System.
Researchers from Curtin University and Geological Survey of Western Australia have discovered the world's oldest known impact crater, dating back to 3.5 billion years ago. The discovery was made in the Pilbara region of Western Australia and provides new insights into the origins of life on Earth.
Scientists found evidence of relatively recent geological activity on the moon's far side, contradicting previous assumptions about its 'geological dead' status. The team used advanced dating methods to track changes and found small ridges formed within the last 200 million years.
Researchers discovered organic molecules on Ceres' surface but found no evidence of volcanic or tectonic activity. The deposits are thought to have originated from impacts by outer asteroid belt bodies, which could have introduced building blocks of life.
A new study by UCL researchers found no lasting changes in the Earth's climate after two massive asteroid impacts around 35.65 million years ago. The impact craters left behind no evidence of a shift in climate over 150,000 years.
Researchers at University of Maryland have discovered that the South Pole-Aitken basin, the moon's oldest and largest visible crater, is more circular than previously believed. The team used high-resolution data to analyze mountain formations around the basin, revealing a rounder shape indicating a more vertical impact angle.
Researchers discovered that Titan's icy surface is warmed by an insulating layer of methane clathrate ice, which relaxes the impact craters' shape. This finding helps explain Titan's unique hydrological cycle and climate.
Researchers at Heriot-Watt University have captured high-resolution images of a five-mile asteroid impact crater buried deep beneath the Atlantic Ocean. The data reveals minute-by-minute chaos after collision, including rocks flowing upwards to the crater floor and an 800-metre-plus high tsunami. The findings confirm the Nadir Crater w...
Researchers at Purdue University and NASA believe Ceres has a dirty ice crust and was once a muddy ocean world. The team used computer simulations to show that ice can be much stronger than previously predicted, contradicting the previous belief that Ceres was relatively dry.
