New research modeling the aftermath of nuclear winter identifies seven nations with unique geographical advantages that could ensure food security and survival. In the event of a catastrophic global collapse, where technological and social...

New chemical analysis reveals that Earth and Mars followed drastically different evolutionary paths during the earliest stages of their formation. Earth and Mars, while sharing a common birthplace in the early solar system roughly 4.5 billion years...

of a broader summer display. Between July and August, Earth traverses several trails of dust left by long‑dead comets and asteroids, producing a series of lesser‑known showers that deliver bright fireballs, slower meteors, and distinct viewing windows....

of years. Since many lunar rocks date to the Moon’s formation era, analyzing this ice could illuminate how water‑bearing asteroids and comets delivered volatiles to the inner Solar System, including the nascent Earth. “The moon witnessed some of the...

continuously refreshed cosmic map will supply researchers with fresh insights into galaxies, stellar populations, asteroids, and a host of other time‑varying objects. COSMOS Field as a Critical LSST Testbed Given its rich legacy of observations, the...

exposures into a 5.6‑trillion‑pixel mosaic that records the position and brightness of galaxies, stars, black holes, asteroids and other sources across visible and near‑infrared wavelengths. A Landmark Survey for Dark Energy Research Originally...

of meteor showers. These displays occur as Earth sweeps through the orbital trails of debris left behind by passing asteroids and comets. As these particles strike the upper atmosphere at high velocities, the resulting friction creates the brilliant,...

and shared cosmic origins, the molecular overlap between the two samples was minimal. This disparity suggests that the asteroids from which these fragments originated were exposed to vastly different environmental conditions during the early stages of...

could eventually serve as a blueprint for mapping other planetary bodies, including the moon, Venus, and various asteroids. Scaling Up the Tianwen-3 Sample Return The mapping initiative is inextricably linked to China’s Tianwen-3 mission, which is...

of both forms. By measuring the ratio of these chiral molecules, scientists can identify potential biosignatures on Mars, asteroids, or icy moons. However, detecting this subtle imbalance in extraterrestrial samples is difficult, as it often requires...

decades, astronomers have debated the genesis of Phobos and Deimos. One leading hypothesis suggests the moons are captured asteroids, which would imply they contain primitive, space-faring material from the outer solar system. A competing theory posits...

Deciphering the Mystery of Martian Moons For decades, astronomers have debated whether Phobos and Deimos are captured asteroids or the result of a massive impact event that scattered debris into Martian orbit. The chemical signature of the moon’s...

A Japanese spacecraft will explore Mars’ mysterious moons and attempt a historic sample return mission in collaboration with NASA. An ambitious international space endeavor is gearing up for a historic voyage to the Martian moons, with NASA playing a...

Cambridge study finds launch costs dropped 96% from $87,000/kg in 1960 to $3,868/kg in 2025, and could fall to $273/kg by 2040. Space Launch Prices Drop Sharply, Forecasts Predict Sub‑$300 Kilograms by 2040 Researchers at the University of Cambridge...

New research analyzing decades-old NASA data has uncovered a hidden clue about Mercury’s past that could reshape our understanding of how the planet formed. New research suggests Mercury has undergone significantly more contraction than previously...

NASA’s Perseverance rover has discovered an unusually hard, light-toned Martian rock that resisted its first attempt to collect a core sample. NASA’s Rover Probes Ancient Martian Catastrophes in Rugged Frontier NASA’s Perseverance rover has ventured...

Scientists have discovered a massive lunar crater, larger than the Roman Colosseum, hidden within 17 months of detailed moon surface data. While conducting a routine examination of lunar imagery on October 24, 2025, Robert Wagner, an image-processing...

A volcanic structure on the Moon’s far side reveals evidence of an ancient magnetic dynamo, suggesting our neighbor had a magnetic field 4.2 billion years ago. Unlike Earth, which maintains a robust magnetic shield powered by the churning of its molten...

Quantum chemical models show that gas grain interactions in the early solar system naturally enriched planetary water with deuterium. The origin of our planet’s oceans remains one of the most fundamental unresolved problems in planetary science. Any...
