New close‑up of asteroid Kamoʻoalewa shows its unique shape as scientists plan detailed studies and future sample missions to uncover its origins. China’s Tianwen‑2 probe has snapped the inaugural close‑up photograph of Kamoʻoalewa, a diminutive...

Five years after launch, NASA’s Lucy mission has uncovered unexpected asteroid structures as it gears up to explore Jupiter’s ancient Trojan swarms. Five years after its departure, NASA’s Lucy spacecraft is already rewriting our understanding of solar...

NASA uncovers a hidden comet, previously misidentified as an asteroid for 30 years, after spotting a subtle orbital anomaly. Astronomers have re‑identified a long‑known near‑Earth object as a faint, active comet after more than two decades of tracking....

Analysis of new samples from asteroid Bennu reveals a surprising origin story that challenges our current understanding of the solar system’s history. Deep-Space Samples Rewrite the Origin Story of Asteroid Bennu New geochemical analysis of material...

A University of Helsinki student has identified a previously unknown comet in Euclid telescope images, marking a milestone for future space exploration. Europe’s Euclid space telescope has unexpectedly captured its first-ever sighting of a previously...

China’s Tianwen-2 probe reaches asteroid 2016 HO3, launching a scientific campaign that could reshape our understanding of near‑Earth objects. China’s Tianwen-2 probe has closed to within 20 km of the near‑Earth asteroid 2016 HO3, marking the start of...

See the 1873 comet as it swings close to Earth, giving binoculars a rare view and marking 150 years of scientific observations. Comet 10P/Tempel 2, discovered in the 19th century, will swing through the inner Solar System this summer under one of the...

bolsters the notion that key ingredients for early biology may have been forged in space and later incorporated into comets and asteroids. Interstellar Cloud Yields First Genuine Sugar An international collaboration headed by astronomer Izaskun...

A new computer model reveals when Earth became habitable, suggesting that the very asteroid impacts once thought to destroy life may have actually enabled it. New three-dimensional computer simulations suggest that the conditions necessary for the...

part 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...

Moonquakes may pinpoint hidden lunar ice, offering a breakthrough that could reshape Artemis mission planning. A novel approach that listens to the Moon’s own tremors could soon reveal hidden stores of water ice at the lunar south pole, offering a...

Get ready for a spectacular autumn in 2026, featuring frequent meteor showers, brilliant planetary alignments, and must-see celestial events. As the Northern Hemisphere shifts into the final quarter of 2026, the night sky is set to host a vibrant...

Scientists find raspberry‑linked sugar near the Milky Way’s core, revealing a surprising interstellar chemical trail. A team of astronomers has reported the first unequivocal identification of a sugar molecule, erythrulose, inside a dense cloud of gas...

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...

Scientists have spotted an unusually large sulfur-containing ring molecule inside a dense cloud near the Milky Way’s center, giving new clues about how complex chemistry may develop long before planets or life appear. Sulfur plays a quiet but crucial...

New research suggests an icy ’Oumuamua lost massive amounts of material over millions of years, revealing a cosmic filter shaping interstellar visitors. Interstellar space might appear to be a vast, empty void, but for frozen objects drifting between...

NASA shares a rare sky photo of a vaporizing meteor streaking across the distant Lacerta nebula, highlighting an unexpected cosmic alignment. A brief meteor blaze cut across the view of the Lacerta nebula, producing a striking juxtaposition of a...
